Curious to see, then we can compare. We tried your mov sample on Shield and -> all fine, therefore I don't think it's something in our ffmpeg demuxer.

Yeah, it's strictly a problem with the combination of Fire TV 4k and Kodi and cropped MOVs -- the cropped MOVs display correctly in Kodi on Windows, in Kodi on Android phone, and in Plex on the same Fire TV 4k. Someone even said they display correctly in Kodi on 2nd gen Fire TV (not 4k) although I haven't verified that. Meanwhile, there is no problem with cropped MKVs.

I should be able to post logs with the converted vid tonight, thank you for your time. If there are any other players you'd like me to test them with on the fire4k, let me know if that would be helpful.
