Comment (by Balling):

 > The result you achieve with FFmpeg 5.0.1 differs from that you achieve
 with the FFmpeg git head

 Because of e645a1ddb90a863e129108aad9aa7e2d417f3615, your original file is
 full range. This was just a bug in ffmpeg, see #9576 (full range of a file
 was being recognized as limited in some cases). Compare your original file
 with ffplay before and after that commit:

 ffplay.exe CAM1_20220823_2907.MP4

 This can also make it obvious:

 ffmpeg -i CAM1_20220823_2907.MP4  -map 0:0 -map 0:1 -c:a aac -ab 320k -c:v
 libx264 -crf 15 -s 960x540 -vf scale=in_range=tv:out_range=pc -pix_fmt
 yuv422p10le -profile:v high422 -preset fast -g 1 -color_trc log_sqrt
 -color_range jpeg output1.mp4
