    Through trial and error of all options, select 60fps H.265 even though it's 29.97, because 30fps option didn't work:

    If the video format was H.265, 2160(x3840)p(UHD-1), 60fps: Type 3, then the "Return" key.

    This only opens in VLC and plays at 2x:

    ffmpeg -i DJI_20250602114429_0004_D-repaired3.h264 -c copy DJI_20250602114429_0004_D-repaired3.MP4

    So need to do:

    ffmpeg -r 60 -i DJI_20250602114429_0004_D-repaired3.h264 \
    -filter:v "setpts=2*PTS" \
    -c:v hevc_videotoolbox -b:v 90M -r 29.97 -pix_fmt yuv420p \
    -tag:v hvc1 -movflags +faststart \
    DJI_20250602114429_0004_D-repaired3_fixed.MP4

    Which does this:

    - Force fps and then filter to play at native 29.97fps
    - 90M bitrate option copied from ffprobe of a good file
    - -tag, movflags for Quicktime

    Or with libx265 instead of videotoolbox:

    ffmpeg -r 60 -i DJI_20250602114429_0004_D-repaired3.h264 \
    -filter:v "setpts=2*PTS" \
    -c:v libx265 -b:v 90M -r 29.97 \
    -tag:v hvc1 -movflags +faststart \
