Introduction
The MedeaWiz® model DV-S4 Sprite® 4K is an Ultra High-Definition digital video
repeater capable of up to 4k @60 fps HDMI output with high quality stereo
audio and Dolby and DTS surround sound with firmware version 20240620 or
later.
It has a direct trigger input and a 2-way communications serial port. The
Sprite® 4K will play a video or audio file in a circular loop, repeating, when
power is applied. It will play different video or audio files by a trigger
input or serial command, and then return to the looping file.
The Sprite® 4K has no black space when looping or changing files. It will hold
the last frame of video until the first frame quickly displays.
It is simple to set-up with an on-screen menu. No programming required. It has
multiple operating mode options to fit many needs.
In the trigger input modes, you can use a push button, other dry contact,
motion sensor or a voltage level change, with your choice of a High or a Low
transition trigger. You can also choose to allow an interrupt from a new
trigger event, or to not allow an interruption of the file playing. You can
trigger a single file, or trigger multiple files in order. Each new trigger
plays the next file. After a triggered file ends, the looping video will play
again until a new trigger occurs.
In the Serial Control Mode you can have a looping video file and control up to
200 other video files to play on command. Once the commanded video ends, the
looping video will play again until a new command is received. Serial Control
can also be used with audio files.
The Hydra® accessory is available to use with the Sprite® 4K in Serial Control
Mode. It adds several additional modes of operation with multiple trigger
inputs, DMX 512 control, MIDI control, and 8 sinking outputs to control lamps,
relays and more.
The Sprite® 4K also has basic “play all” file modes to play all files on the
SD card or USB drive in order or randomly when power is applied. Files will
continue to play until power is removed.
A remote control is included for initial set up of the Sprite. Your settings
are retained in memory. Anytime power is applied the Sprite will automatically
play according to the settings you made.
The Sprite® 4K is one of the most energy efficient “green” video repeaters
available today. Using only 5 Volt DC power at an average of 500 mA, it takes
only about 2.5 Watts to run.
FCC, CE UKCA and RoHS certified.

Sprite® 4K Quick Start Guide
The MedeaWiz® Sprite® 4K ships with the Video Output set to HDMI and the
Control Mode set to “Trigger Low No Interrupt” to use a pushbutton trigger for
video files. Most users can simply connect their HDMI monitor and install
their SD memory card, with files named in the same way as the earlier model
MedeaWiz players. Example 1: You have file(s) that you need to run in a loop
when power is applied: Using the IR remote control, enter the on-screen menu
by pressing the Setup key, and set the Play Mode. For Video files use Video
Repeat All, for Audio use Audio Repeat All, for photos use Photo repeat all.
Do not put the files in a folder.
Example 2: You want to trigger a file with a push button or motion sensor: You
must have a looping / ambient file named 000.xxx and a trigger file named
001.xxx. If using multiple trigger files, name them in numerical order 001,
002, 003. and etc.. Using the IR remote control, enter the on-screen menu by
pressing the Setup key, and set the Control Mode to one of the Trigger Low
choices for a push button, or one of the Trigger High choices for our motion
sensor. Example 3: You want to use the TTL Serial Port to control multiple
files: You must have a looping / ambient file named 000 and name the other
files 001, 002, 003 and etc. in order, up to 200. Using the IR remote control,
enter the on-screen menu by pressing the Setup key, and set the Control Mode
to Serial Control, and set the Baud Rate to match your external controller.
For any external Trigger type or Serial Control Mode: Set the Play Mode =
Video Control Mode for video files, OR Audio Control Mode for audio files.
Always have a looping / ambient file named 000 if using any Trigger choice or
Serial Control. The 000 looping file can be a black video file if no video is
wanted until a trigger or command. For Audio files you can use a silent audio
file. We suggest the looping file be at least 30 seconds long and may be much
longer. Do not put the files in a folder. Only put media files on the SD card
or USB drive.
Please read the Trouble / FAQ section on page 38 for helpful information.

Address Mode
Select an address, if desired, for serial communications to multiple Sprites
from one control. Only applies if the setting Control Mode is set to Serial
Control.
Address is set to Do not use Address If you are using a single Sprite® on the
serial communications line, or using a Hydra® input expander, in most cases
you should choose the Do not use Address option. Address is set to 0xE1
through EF If the Sprite® 4K is set to an Address, it will only follow
commands preceded by the correct address byte. The Host can transmit commands
to many Sprites on the same serial line. This requires a 2 byte transmission:
Address, Command. i.e. 0xE1, 0x03 will play the file named 003 on any player
with an address that is set to 0xE1. All players set to any address will also
respond to the Broadcast Address 0xE0. You should only use 1 Sprite® for the
feedback to the Host to avoid data collisions. You should only connect the RX
inputs and Grounds of multiple Sprites together. See page 30 for a wiring
example. The MedeaWiz SS-38 serial splitter is available to connect several
Sprites using the standard 3.5mm 4 pole cables to one controller without
signal loss.

Serial Feedback
Select one of the serial feedback types to report status to your serial
control device. Only applies if the setting Control Mode is set to Serial
Control.
Full Reporting The Sprite® 4K will echo any command received. A single hex
byte is sent several times per second representing the file number currently
playing. When the end of a file is reached, a single Hex byte 0xEE is sent.
Minimal Reporting The Sprite® 4K will only report the file number playing once
at the start of the file. It will report 0xEE at the end of a file. It will
return data from a command request. Command Request Only The Sprite® 4K will
only report data when a request command is received. This can be useful if
multiple Sprites or other devices using Addressing are sharing a serial bus.

Firmware Revisions History
We recommend that you do not update the firmware unless you require one of the
new features or bug fixes. There is a risk, due to a few reasons, that the
firmware does not install properly and renders your Sprite useless. We do not
cover this under warranty. Version 20230728 First public release. Known bugs:
Surround Sound output not available. When power is first applied, sometimes
the Setup Menu shows for a second before the file plays. New out of the box
and after restoring default settings, and only in Audio Control Mode and using
Trigger Low no Interrupt, triggers will not respond correctly. You can change
to another setting and then back to correct the issue. Serial Control commands
0xCA and 0xC9 will not echo back the command. Command 0xCB will echo back 2x
whereas it should only be once.
Version 20231120 Second public release. Added code to allow installing a
custom boot-screen animation. Known bugs: Surround Sound output not available.
New out of the box and after restoring default settings, and only in Audio
Control Mode and using Trigger Low no Interrupt, triggers will not respond
correctly. You can change to another setting and then back, to correct the
issue. Serial Control commands 0xCA and 0xC9 will not echo back the command.
Command 0xCB will echo back 2x whereas it should only be one.

Firmware Upgrade
Do not upgrade the FW unless you absolutely need something in a newer version.
If you have a power glitch or a corrupted file, a bad USB drive or etc., you
risk “bricking” the Sprite making it useless. We do not cover this under
warranty. The firmware will be in a compressed zip folder and should be named
update.zip Place the update.zip folder on an SD or USB drive along with other
video files. Do not “Extract” the files from the update.zip folder. Insert the
SD card or USB drive into the Sprite 4K and plug in the power. The update can
take several minutes. It is recommended to use a battery backup
uninterruptable power source when performing an update. During the update you
will see the images below. Do not stop the update until after the last image
“Upgrade Completed Successfully” appears.

Trigger Choices Explained
Trigger Low requires a transition from a positive voltage down to ground.
Since the Sprite has an internal resistor holding the input at positive 3.3
Volts, you only need to provide a ground to trigger. For example if you are
using a push button wired from the input terminal 2 to ground terminal 4 as
shown on the following page, pressing the button applies the ground to the
input causing the transition and a valid trigger event.
Trigger High requires a transition from ground up to a positive voltage. Using
the example above, if the push button was held down normally, then released,
the trigger would occur on the release.
The Sprite requires a transition to occur on the input to cause a trigger.
Holding the button down or up will not cause another trigger because there
must be a transition. Trigger Low requires button up to down, and Trigger High
requires button down to up.
Trigger with interrupt will allow a new valid trigger event to interrupt a
triggered file currently playing. If there is only one trigger file 001 on the
SD, it will re-start file 001 at the beginning. If there are more trigger
files on the SD, it will start the next file playing. There is an
approximately 1 second delay built in to prevent rapid re-staring of files.
Trigger No Interrupt will NOT allow a new valid trigger event to interrupt a
triggered file currently playing. The currently playing triggered file will
play completely to the end before any new trigger is allowed.
Trigger Delayed will delay playing the triggered file until the looping file
000 has completed. When a valid trigger event occurs while file 000 is
playing, the Sprite will wait until the end of the 000 file to proceed with
the triggered file. Once the triggered file is playing, there is no
interruption. It will play to the end. The Sprite will only allow a trigger
event while the looping file 000 is playing.
This allows multiple trigger files to be used. Each new valid trigger by the rules above will cause the next file on the SD to play. After the last file has played, the next valid trigger will play file 001. The looping file 000 is not considered a trigger file. For ease of use trigger files should be named in order 001, 002, 003, and etc. up to 200. If you desire a random distribution of play, you may place multiple copies of the files on the SD and randomly assign them to the sequenced number names.

Push Button Wiring to the I/O Port
Using a pushbutton or other dry contacts
MedeaWiz® Sprite® 4K
The Control Mode should be set to Trigger Low No Interrupt or Trigger Low with
Interrupt or Trigger Low Delayed.
The screw terminal adaptor shown above on the right is included with the
Sprite® 4K. Note that the numbers near the screws match to the numbers on the
plug at the left, which is used in examples later in this manual.
You can trigger multiple Sprites from one pushbutton. Do not wire the power
(1) or TX (3) pins together between multiple units. The MedeaWiz SS-38 serial
splitter is available to connect several Sprites using the standard 3.5mm 4
pole cables to one push button.
23 | P a g e
MedeaWiz® Sprite® 4K
.
Serial Communications Wiring to the I/O Port
The Sprite® 4K can be controlled by a Show Control or micro controller like a
Basic Stamp, PIC, Atmel, Arduino, Raspberry Pi, or etc. using serial
communications at 3.3V or 5V levels. Note that RS232 levels from a PC or PLC
serial port will require a level translator like the MAX3232 series. Do not
allow negative voltage below ground to be applied to the Sprite®. The Sprite®
4K can supply 5V DC at up to 100 mA to power your micro controller.
Alternately, you can power the Sprite® 4K from your controller. You must have
a 5 volt DC regulated supply at 600mA. Use 24 AWG wire or larger. Do not use
the Sprite’s included power supply together with an external power supply.
You can also use the included AV cable in the I/O port. Use the red RCA to
send commands to the Sprite®, the yellow RCA for the Sprite® to report back to
your control, and the white RCA for 5V power from the Sprite®. We suggest you
cover the unused RCA plugs with electrical tape to avoid shorting the power
supply and burning the internal fuse.
If you get a cable elsewhere, check to see that the wiring is the same. We
have seen some cables where the red, yellow and white RCA are wired to
different poles on the 3.5mm plug.
24 | P a g e
MedeaWiz® Sprite® 4K
.
PLC Wiring to the I/O Port
The Sprite® 4K can be triggered from a Programmable Logic Controller using
relay “dry contacts” or a transistor output.
The sinking output above is the preferred method if dry contacts are not
available.
The Sprite® 4K has an internal 22K pullup so the Sourcing output requires a
low resistance from Output to Common to pull the Sprite’s internal voltage
down to a “LOW”. The 1K* shown is an example and can vary depending on the +V
voltage. Consider the Watt rating of the resistor. Do not allow a negative
voltage to be applied to the Sprite® 4K. Do not share PLC outputs with relays,
motors or solenoids /valves. These devices can produce negative voltage
spikes. Keep them on separate isolated outputs away from the Sprite® 4K.
25 | P a g e
MedeaWiz® Sprite® 4K
.
Motion Sensor Wiring to the I/O Port
There are many possibilities to add a motion sensor to the Sprite® 4K. Small
PIR motion sensors are available that use 5 Volt power and have a TTL voltage
output. These can be powered directly from the Sprite’s I/O port. Set the
Sprite’s Control Mode to Trigger High No Interrupt or Trigger High Delayed.
Note that you can’t wire multiple Sprites to one motion sensor due to the
voltage drops of the added Sprites. Use the MedeaWiz SS-38 serial splitter or
a relay or a sensor with dry contacts to trigger multiple Sprites. A relay
example is in the MSA-B manual.
Wiring a 5 Volt motion sensor
We offer the MSA-B Stealth motion sensor for a plug-and-play solution. Set the
Sprite’s Control Mode to Trigger High No Interrupt or Trigger High Delayed.
See the MSA-B manual for complete details. The MedeaWiz SS-38 serial splitter
is available to connect the MSA-B to several Sprites using the standard 3.5mm
4 pole cables without signal loss.
26 | P a g e
MedeaWiz® Sprite® 4K
.
Schematic of I/O on the Sprite® 4K Circuit Board
The Sprite is designed to work with serial data at 3 to 5 Volt TTL levels.
Trigger input can tolerate industrial 24 VDC sensors that have NPN transistor
or relay outputs. Do not allow negative voltage to be applied to the inputs.
Do not apply an AC voltage. A negative voltage applied at the input / output
may damage the Sprite and void the warranty. Many serial devices including
computers, PLC controls, building lighting controls like AMX and Crestron and
etc. have standard RS232 that will drive the output up to negative 12 volts.
You must use a level converter with these standard RS232 devices. The MAX3232
or similar will convert them to the 5 Volt TTL levels for the Sprite. Micro
controllers such as Arduino, Basic Stamp, PIC, Atmel or etc. are using serial
communications at 3.3V or 5V levels. These can be directly connected to the
Sprite. Pre-made controller boards like the Arduino and Raspberry Pi may have
both TTL level at output pins and also standard RS232 levels on a port
designed to connect to a computer. Don’t connect the RS232 port without a
level translator. Direct connection to the processor pins is fine. The Sprite®
4K trigger input can tolerate up to +24 VDC. The input blocks positive voltage
and requires a low / ground to trigger. Negative voltage will be shunted to
ground through a 22 resistor / fuse and may damage the Sprite.

Serial Port Control from your Show Controller or Micro-processor
For simple file playing, the serial codes are the same as the codes for the
earlier MedeaWiz® models. You must have a file named 000. Name others 001,
002, etc.. Set the Play Mode to Video Control Mode for video files, or Audio
Control Mode for audio files. Set the Control Mode to Serial Control. Set the
Baud Rate to match your external controller. Serial communications is on the
3.5mm 4 pole jack at 2400, 4800, 9600, 19200, 38400, 57600, 115200, 921600, or
1500000, 8N1 at 3.3 to 5 Volt TTL levels. The factory default is 9600 baud.
Lower baud rates can be more reliable if you are using relatively long serial
cables. Send one byte, Decimal 1 (Binary 0000 0001, Hex 01) to play file 001.
Send Decimal 2 (Binary 0000 0010, Hex 02) to play file 002 and etc. Do not
send any other bytes such as a line-feed or a carriage return. Send only one
byte. Make sure your program is sending the NUMERICAL value, not the character
(CHAR) value. Many programs default to sending the character unless you
specify otherwise. The number 1 sent as a CHAR is actually Decimal 49 and will
play file 049 if available. The Sprite® 4K will report back to the Host
controller according to your “Serial Feedback” setting in the Setup Menu. The
Sprite® 4K can supply 5 Volts DC on the I/O port for your micro-controller at
up to 100 mA. A short on this supply may result in the internal fuse burning
and will void the warranty. Note that true RS232 levels from computers, some
PLC’s and some other devices use negative voltages and will require a level
translator like the MAX3232 series. Do not allow negative voltage below ground
to be applied to the Sprite® 4K. This will void the warranty.
Level translator example to convert real RS232 to TTL level
The MAX3232 can be powered from the Sprite® 4K. Connect all Grounds together.

Serial Port Control Multi-Drop Addressing Wiring
Multiple Sprites may be connected to a single serial control bus. You can use
one serial output from your controller to control multiple Sprites. Connect
all of the Grounds together and connect all of the RX Inputs together, and to
your controller’s TX output. Set an address on each Sprite® 4K and it will
only respond to commands from your controller preceded by that same address.
More than one Sprite can have the same address if you want them to respond to
the same commands. All Sprites that are set to any address will also respond
to the Broadcast Address 0xE0.
Limitations on the number of Sprites on the bus include length of wire, type
of wire and baud rate. Low capacitance wire and lower baud rates will allow
longer distances and / or more Sprites on the bus. The MedeaWiz SS-38 serial
splitter is available to connect several Sprites using the standard 3.5mm 4
pole cables to one controller without signal loss. It has a buffer / driver
for each output and may be chained to add 8, 16, 24, etc. Sprites.

Further explanation of some serial commands
0xC9 Puts the Sprite 4K in low-power sleep mode. No video output and no audio
output. This allows your monitor or projector to sleep since no video is
signal is present.
0xCA Wakes the Sprite 4K and begins file play at the point of the file where
it went to sleep. Note that later firmware version 20240620 will start playing
file 000 at the beginning.
0xCB Request the total number of files on the SD card. The Sprite® will send a
feedback byte telling the total number of files on the SD card. The Sprite®
feedback will be CB, CB, xx where xx is the number of files in Hexadecimal.
0XCC Request the file number currently playing.
0xE0 to 0xEF Address numbers for the Sprite®. If the Sprite® is set to an
Address E1 to EF in the Setup Menu, then the Sprite® will only follow commands
preceded by the correct address. All players set to an address will also
respond to the Broadcast Address E0. The Host can transmit commands to many
Sprites on the same serial line. You should only use 1 Sprite® for feedback to
the Host to avoid data collisions. Note that some addresses are also used as
commands. If the Sprite is set to Do not use Address, you can use these
commands normally. If Sprites are set to an address, you can still use these
commands following the Address byte. As example, with a Sprite set to address
E9, you can still use the Volume up command E9. Transmit 2 bytes: Address,
Command as E9, E9. It is not recommended to mix Sprites set to Do not use
Address with those using an address on the same serial line as unintended
results may occur.
0xE8 Mute the audio. Mute only. Mute command does not toggle on / off.
0xE9 Increase volume one step for each command received. If the Sprite® was
Mute, the first 0xE9 command will cancel Mute and return to the previous
volume level.
0xEA Decrease volume one step for each command. If the Sprite® was Mute, the
first 0xEA command will cancel Mute and return to the previous volume level.
0xEF Play – Resume play after a Pause. Play command does not toggle Play /
Pause. A Play command will Cancel FF>>or FB<< in progress.
0xF0 Pause – Does not toggle Play / Pause. You must send 0xEF Play command to
resume. A Pause command will Cancel FF>> or FB<< in progress
33 | P a g e
MedeaWiz® Sprite® 4K
. 0xF5 Returns the current position in the file playing as the number of
milliseconds. The return will be 0xF5 followed by 4 bytes representing the
position. Low Byte is first. 0xF6 Seek to your specified position in the file
and begin playing. Example: Send 0xF6, xx, xx, xx, xx. It is not necessary to
send zero-value high bytes. 0xF7 Returns the total length of the file in
milliseconds. 0xFC Select Loop Command can make any valid file on the SD or
USB the looping file. Valid file numbers are 0x00 up to 0xC8 (files named 000
up to 200) Send 2 bytes, 0xFC, 0xXX where XX is the new file number to loop.
This file will be the looping file until a new 0xFC command is received or a
power cycle. After a power cycle, the default file 0x00 (the file named 000)
will be the looping file. It can also be combined with an address as 3 bytes
when the Sprite® 4K is set to an Address. For example 0xE3, 0xFC, 0x05 will
instruct any Sprite® 4K with address set to E3 to loop the file named 005. Or
you could use the Broadcast address 0xE0 to cause any Sprite set to any
address to follow the command.

IR Remote Control
We use a generic remote control that is used for various models of video
repeaters and DVD players. Not all buttons / functions will respond, and some
are only valid in certain modes. Most of our Customers will only use the
remote for initial setup of the Sprite® 4K. This is an IR control, and needs
to be pointed directly at the front of the Sprite. The Sprite may respond to
some other device’s IR remote in unwanted ways. You can use the blue FILE
button along with orange Arrows and green ENTER keys to manually view or play
files for testing. Using the remote to manually play a file will take the
Sprite out of automatic play modes. Remove power or go into the Setup Menu and
then exit it using the yellow Return button to resume automatic play modes.
You can also use a USB computer mouse with the Sprite 4K to enter the Setup
Menu and make changes without the remote control. Right click to enter and
exit the menu. Point and left click to make selections. If you have no video
output, use the HDMI or AV button to set the Sprite video accordingly.

Power Supply
The Sprite® 4K is one of the most energy efficient “green” video repeaters
available today. Using only 5 Volt DC power at an average of 500 mA, it takes
only about 2.5 Watts to run. The Sprite® 4K requires a regulated 5 Volt DC
power supply, which is included in the US. Sprites sold in other countries may
instead include a USB power cable to use with a customersupplied USB power
source. Verify with your local MedeaWiz® distributor. The power connection
takes a barrel plug with 1.35mm ID and 3.5mm OD, center Positive. Use of a
wrong power supply will void the warranty. The Sprite® 4K can supply 5 Volts
DC on the I/O port for your micro-controller at up to 100 mA. A short on this
supply may result in the internal fuse burning and will void the warranty.
Alternately, you can power the Sprite®4K from your controller. You must have a
5 Volt DC regulated supply with 600 mA available. Use 24 AWG wire or larger.
Do not use the Sprite’s included power supply together with an external power
supply. Multiple Sprites can be powered from a single regulated 5 Volt supply
that has ample current capacity.

Trouble FAQ
MedeaWiz® Sprite® 4K
My File will not play or will not trigger
Do not use folders. Put files directly on the root of the SD or USB.
Try playing the file using the remote control. Press the blue File button,
then navigate to the file using the green Enter key and the orange Arrow keys.
Select the file and press Enter.
If the file plays, it may not be named properly or the Sprite® is not in the
correct Control Mode. If using video files, the Sprite® must have the Play
Mode set to Video or Video Control Mode. If using audio files, set to the
Audio or Audio Control Mode. Control Modes require at least 2 files. The
looping file must be named 000 and the first trigger file named 001.
If the file will not play by using the remote control, then it may be corrupt
or made with parameters not supported by the Sprite® 4K. Make sure the pixel
size is a “television” size, 4096 x 2160, 3840 x 2160, 1920 x 1080, 1280 x
720, 720 x 480 or 640 x 480 etc. Videos made for websites at odd pixel sizes
may play on your PC but may not on the Sprite® 4K. Refer to the chart on page
37 for maximum bit rates and CODEC’s supported. Some other pixel sizes will
play with various results. For smooth transitions between files, they should
all be made the same pixel size, frame rate, bit rate, CODEC, and etc..
No video output on my monitor
If you do not see any video or the Setup Menu displayed, verify the blue power
LED is on.
Users often switch the video output by accidentally pressing a button on the
remote control. Try pressing the HDMI or AV keys on the remote to switch the
outputs. Point the IR remote directly at the front of the Sprite® 4K. Verify
your monitor is set to the input used. Verify the monitor and HDMI cable are
good by swapping or trying another device on the input.
Many computer monitors and older televisions are not capable of playing 4K
video. If unsure about your monitor / TV, find another that is rated for 4K
video. Then set the Sprite® 4K video output to a lower HDMI setting of
1920×1080 or lower and try again with your other monitor.
My Sprite® 4K feels warm to the touch
The Sprite’s aluminum housing is designed to be part of the heat management
system. The internal microprocessor has a heatsink that transfers heat to the
outside air through the housing.
While it is normal for the Sprite® 4K to feel warm, if the ambient temperature
is well over 100F (40C), extra heat management may be desired. Simply placing
the Sprite on a metal surface can reduce the temperature. A clean, unpainted
aluminum plate, at least 12 x 12 inches (30 x 30 CM) works well.

Should I use an SD card or USB drive to hold the video files? While files will
play from the USB port from a USB drive, some UHD video may not play well from
some USB drives. For high bit rate files we recommend using the SD port with
an SD card of sufficient speed to match your video file’s bit rate. For some
HD video files a Class 4 may be ok, while UHD 4K files may need a faster Class
10 at minimum. Test your video. I accidentally changed the language and now I
can’t read the Setup Menu You can reset the Sprite® to factory defaults to
display in the English language without viewing the monitor by these steps:
- Remove the power plug for 10 seconds and then restore power 2) Wait 10
seconds or longer for start-up to finish 3) Press the Setup key on the remote
control 4) Press the down arrow key 9 times 5) Press the Enter key 2 times
Do I have to name the files with those numbers or can I use names? A) For Play Mode = Video Control Mode or Audio Control Mode (any Trigger or Serial Control use): The Sprite® searches for the 000 to use as the looping file, and searches for 001 to use as the trigger. However, you can name them this way:
000.myfilename.xxx or 001.someverylongnamefile.xxx
We suggest you use the numbers 000, 001, 002, etc. to test your files as a starting point, and then add the longer names if you want them.
B) For Play Mode = Video Repeat All, Audio Repeat All, Photo Repeat All (Not Trigger or Serial Control) File play order will follow alpha-numeric sort order.
To keep it simple you can just use the numbering system 001, 002, 003, etc. to play files in order.

Can I synchronize 2 or more Sprites to play together? The Sprite® 4K has no
way to Genlock or synchronize with any external device or another Sprite at
frame accuracy, however they sync quite well for many applications. You can
start trigger files on 2 or more Sprites with a single pushbutton or serial
control. There are very slight differences in the internal oscillator
components that allow Sprites to run at slightly different frame rates. There
can be a few frames difference between players. This is much better than the
original Sprite model DV-S1. Depending on your application and video files,
the frame rate difference may be acceptable and unnoticed, or may not be
acceptable. You should use the same encoding parameters, CODEC, pixel size,
frame rate, bit rate and etc. for all files for best results. The MedeaWiz
SS-38 serial splitter is available to connect several Sprites using the
standard 3.5mm 4 pole cables to one controller without signal loss. How short
or how long can my files be? For all video and audio files: Any file under
approximately 3 to 5 seconds may be a problem. If they are too short, there
may be unwanted results in some control modes.
The 000 loop / ambient file should in most cases be longer. A longer loop file
will allow your SD card to last longer. A short file looping continuously
reads a small area on the SD card. A long file stored across more bytes of the
SD results in less reads per byte over time. All SD and USB have a MTBF rated
average number of reads. This number is very large, but in an application that
runs all day, every day, this will add up. If you make the 000 loop file 10
times longer, your SD card should last 10 times longer as well. Keep in mind
that if you are using one of the Trigger Delay settings, your trigger file
will not play until the end of your 000 loop file.
Most users will never have an issue with a file that is too long. The time
limit for the length of any file depends on the file encoding and bits used
per second. Lower bitrates, lower frame rates and reduced pixel size can
increase the time allowed. The file size is normally limited to 4 GB. Larger
files may be stored on the SD card or USB drive if it is formatted to exFAT or
NTFS.
The maximum SD card size for the Sprite 4K is 512GB. The USB port will support
a USB drive or SSD with no limit on size.
