Music / video playing:

Question 1: Why can’t I play my music, and its file format is one of those file formats that you claims in the description that can be compatible with the device.
Answer:
Laboratory tests show that the device is compatible with common audio format files, including MP3, OGG, APE, FLAC, WAV, AAC-LC, ACELP, M4A, etc. However, it does not support any format music with a bit rate higher than 3000kbps. That is to say,
whether it is WAV, FLA Cor APE format, as long as its bit rate exceeds 3000kbps, it cannot be played. And show “Invalid file format”. It depends on the hardware performance of the device.

How to calculating the bit rate:
Bit Rate (Kbps) = File size (GB) 1024 1024 8 / playback time (S)Bit Rate (Kbps) = File size (MB) 1024 8 / playback time (S)
For example: The size of your music file is 669.3MB, and the play time is 66 minutes, and the bit rate is: 669.3 1024 8 / (66 60) ≈1385 Kbps.

If your music is out of the acceptable bitrate range above, please lower it with a conversion tool before playing. If not, please contact us for further assistance or return. Also, if convenient, please send us a copy of the music file so we can investigate.

How to calculating the bit rate: confirmation page that pops up.
Bit Rate (Kbps) = File size (GB) 102410248 / playback time (S)Bit Rate (Kbps) = File size (MB) 10248 / playback time (S)
For example: The size of your video file is 8.96GB, and the play time is 125 minutes, and the bit rate is: 8.96102410248/(12560)≈10022 Kbps
