If I check with MediaInfo, the video stream bit rate, bits/(pixel*frame) value
and stream size are smaller.

I don't think FFmpeg drops video data for your command
line and I don't think MediaInfo would be able to show
you such a drop.
Feel free to use third-party tools to extract the video

Hello,
I'm trying to remux a MXF XAVC file with the exact same video but only 2 out of
the 4 audio tracks.
For that I use this command:
ffmpeg -i INPUT_FILE -c copy -map 0:v -map 0:a:0 -map 0:a:1 OUTPUT_FILE
The thing is, some video data are lost during the remux as my file is smaller
than it s
