ffmpeg command line for lessless encoding

[stax76]

Is there something that can be improved in this command line? I have to admit I'm clueless about lossless encoding so I just shamelessly took the command line that megui is generating. -hide_banner and -y is from me, -sn and -an is clear but the rest? Might there be better codecs?

D:\Projekte\VS\VB\StaxRip\bin\Apps\ffmpeg\ffmpeg.exe -y -i D:\Temp\StaxRip\anamorphic_temp\anamorphic.avs -c:v ffvhuff -threads 0 -sn -an -context 1 -vstrict -2 -pred 2 -hide_banner -y D:\Temp\StaxRip\anamorphic_temp\anamorphic_lossless.avi

What do you mean with "better"?

I think "ffv1" will probably achieve significant better compression than "ffvhuff", but it's also a lot slower. And, of course, there is libx264 in "lossless" mode.

(Lagarith would be another option, but last time I checked FFmpeg only had a decoder for it)

[stax76]

I don't plan to make it configurable so it should be suitable for average users, it's for a feature to pre-render slow scripts into lossless AVI like what megui does.

[juhok]

There's encoder and decoder for utvideo also.

[Atak_Snajpera]

Yeah. I would use UTVideo. Fast , good compression ratio and easy to edit in NLE.

[Groucho2004]

+1 for UTVideo

[stax76]

I don't see utvideo with ffmpeg -formats

[poisondeathray]

I don't see utvideo with ffmpeg -formats

ffvhuff is slower but compresses better:

ffvhuff is slower but compresses better:Try "-pred median" with utvideo.

[stax76]

Try "-pred median" with utvideo.

Great, same size then ffvhuff now but 3 times faster.
