 '''Summary of the bug:'''

 * MKV to MOV remuxing using ProRes Proxy creates a green artifact in
 bottom right in some players such as Premiere Pro (using 13.1.4 build 2
 which is latest):

 * Artifact doesn't exist when h.264 nvenc is remuxed MKV > MOV

 * Both OBS 24 Internal Remux and Standalone FFMPEG Remux have been tested
 (using: .\ffmpeg -i "testvideo.mkv" -map 0 -c copy

 * If the video is re-encoded the green bar disappears: .\ffmpeg -i
 "testvideo.mkv" -map 0 -c:v prores -profile:v 3 -pix_fmt yuv422p10le -c:a
 copy "testvideo_reencoded_video.mov"

 * If an .MOV with same settings is written from OBS, the green bar doesn't

 * The green bar doesnt appear in the MKV or remuxed MOV in PotPlayer or

 * Thought is the header is being padded upon remux in a way certain NLE's
 don't like?

 * ProRes files are being being recorded in OBS 24 using Xaymars plugin:
