I used Handbrake with default settings and transformed previous AVI video recordsdata to MP4.
The dimensions may be very lowered:
Dimension:
80M new.mp4
116M previous.avi
I ponder if there’s a high quality distinction. With my “dangerous” eyes I can’t see the lowered high quality. Learn how to technicaly confirm that?
What actual output I want to check (apart from my eyes with play the film)?
ffmpeg
and mediainfo
output for each the unique file and the brand new file in MP4
