FFmpeg H.264/265 lossless

How do you convert videos into the H.264 and H.265 lossless video codecs using ffmpeg and Shutter Encoder?

You really should start reading and not ask to be spoon-fed on any thing that takes your fancy.

And the other day you asked how to make videos smaller. Encoding h264/265 as 'lossless' uses an encoding crf setting of 0. And then you actually end up with, probably, a much larger file than you started with.

for ffmpeg

x264

-c:v libx264 -qp 0

x265

-c:v libx265 -x265-params lossless=1

The filesize for lossless will usually be several times larger than the original , if you started with lossy compression , because video gets uncompressed / decoded first, then re-compressed

What my video has more than one audio track (like 8 or even 25) and I want to keep all audio?
