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. 

I ran the command you gave and did all the output resolutions suggested. I also did versions of the 800 resolution converted to mkv and mp4.

In VLC and Plex on Fire 4k, all played back correctly -- black bars on all except 1056 and 1072 where I think they were cut off by overscan.

In Kodi on Fire 4k, all played back stretched, with no black bars. Since 100% of all the other hundreds of cropped MKVs in my collection play back correctly, I'm guessing there must be something different with these particular streams regardless of what container they're packaged in?

Here is the log including playback of all the files you suggested (output800.mov etc), and your cropped Pulp Fiction sync-test.mkv which displayed correctly: aduzulerim.kodi (paste)
