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.

If MKV containers work perfectly you could always use FFmpeg to convert your MOV files to an MKV (or likely MP4 as well) container without having to re-encode.  Save the following code as a batch file, ie. FFmpeg_mov2mkv.bat, making sure your change the SET FFMPEG variable line to reflect your FFmpeg executable path.

FFmpeg_mov2mkv.bat:


@echo OFF

SET FFMPEG="C:\FFMPEG\ffmpeg.exe"

FOR %%a IN ("*.mov") DO %FFMPEG% -i "%%a" -c copy "%%~na".mkv

Then just place any MOV files to be converted to MKV container into the same folder as the batch file and double-click it.  All MOV files will be converted to MKV files in seconds without needing to re-encode.  If you'd prefer to convert to MP4 then just change the end of line 3 from .mkv to .mp4 and resave the file as FFmpeg_mov2mp4.bat.
