I didn't get what is the issue. Can you please attach two pictures to
compare: one with the "pixelation" issue, another - without?

This looks like insufficient bitrate for MPEG-4 codec.
Mediainfo shows you have 768x480@30fps with bitrate ~1300Kbps, which is
~0.1 Bits/(Pixel*Frame)
Try increasing like 10x times to see if it makes difference (ex, 10Mbps).
If that helps, you will have to lower bitrate till you get accepted quality
For reference, my H264 recorded videos have Bits/(Pixel*Frame): 0.651

At the risk of sounding stupid,
I think you mean *ffmpeg_bps 1200000* to *ffmpeg_bps 12000000* to test?
If that helps how do I lower the bitrate till I get accepted quality?

Yes
First try ffmpeg_bps 12000000. No more pixelation? Try ffmpeg_bps 6000000.
Still no pixels? Try ffmpeg_bps 3000000. Pixels are back? Etc
