FFMPeg Video Conversion Options?
Not too shy to talk
Not too shy to talk


See User information
Hi guys,

I updated to the new FFMPeg and noticed that my old command line for converting videos doesn't work anymore...

FFmpeg_ppc -sameq -i

I was under the impression it caused FFMpeg to keep the quality of the videos the same.

So now I get a message telling me to use a new argument...

FFmpeg_ppc -qscale 0 -i

But I'm now seeing much more grainy/chunky/blocky videos. Not good.

I'm still delving into the docs on FFMpeg.

I was wondering what you guys are using for converting Youtube vids to more Amiga-friendly (aka DVP-friendly) formats?

Thanks,

PJS

Replying to myself.... but here's what I found... The devs
repeat over and over that the "-sameq" argument didn't do
what appeared to do, except by pure happenstance, so they
removed it... or something like that. ;)

Instead, they suggest you should become an expert in video
codecs and find/use only the arguments that suite the exact
formats of video you are going to and from.

A bit beyond my desire.... ;)

Anyway, I did find the "-qscale" option with the "best" (1)
setting seems to keep the quality of video conversions up.

For my purposes of converting YT .mp4 videos to .avi's, I'm
finding this syntax yields high quality results that work
well in DVPlayer:

ffmpeg -i ram:input.mp4 -qscale 1 ram:output.avi

OTOH, the files get rather large... ;)

Good luck,

PJS
