now:
I have a video .mp4 file, it's 792,4 Mb, made with KDEnlive
with this simple command line
ffmpeg -i original_file.mp4" shrinked_file.mp4
it goes down to 186,6 Mb 😵
#video
I watched them both and I don't perceive any difference !
How is this even possible ??

•`ffmpeg -codecs`
Whatever is default for your ffmpeg I guess :)

•the viseo is h.264 in both files
BUT
the original bitrate is 3477
in the shrinked version, it's 742
Audio is mpeg-4 AAC for both
BUT
The original kbps is 241
the shrinked one os 128
But I swear I see no difference when I watch it !!

•would you paste me the command line ?
I can't figure it out myself
KDEnlive requires about 40 minutes to export in h.265/HEVC

•Also kdenlive is probably running without gpu acceleration and not multithreaded but that's another can of worms.
ffmpeg -i INPUT -c:v libx265 -an -x265-params crf=25 OUT.mp4
crf is Constant Rate Factor (basically quality) from 0 (best quality) to 51 (lowest filesize)

•the previous conversion run at 2.7 speed
this one is running at 0.31 speed !
This video thing is a black hole !! 🤐
