MKV video is not supported by most portable devices including Galaxy Tab 3, so the transcode to mp4 is necessary and should be able to play on Galaxy Tab 3. Many users complained that, after a video conversion from mkv to mp4 and when trying to transfer it to Samsung Galaxy Tab 3, it keeps coming up with some kind of error, saying the file is not playable. What’s the problem?
While this error I encountered before, a friend indicated it was about file size. Most android tablets including Samsung Galaxy Tab 3 only recognize SD cards formatted in FAT 32, this limits a single file size less than 4GB, if your movie or video is larger than 4GB, same error would appear. There are two ways to to avoid this situation. The first method, compress the MKV file to the greatest extent, but doing so may affect video quality, the greater the compression ratio, the poorer the video quality. The second method, split large video files into smaller pieces.
