ffmpeg pipe to x264, useful for .avs?

[colargol7]

Hi guys

You may find my question stupid,
I was wondering if there are somme differences (speed, quality, memory usage...) between :
- using x264 with an avisynth script
- reading .avs with ffmpeg pipe to x264

Is there a "best solution" to encode .avs into x264?

Thanks!

Loading the script directly into x264 will let it print any errors. Using ffmpeg you will get the usual error clip, which it will convert as necessary and send it on. In terms of speed, not having an overhead associated with the pipe and ffmpeg will make the direct loading faster. (This is all assuming you're on 32-bit Windows)

ok, thanks for answer :)

If you wanted to encode from avisynth (16bit source) to 10bit h264 lossless or otherwise using a 10bit build of x264, then avs2yuv or avs2pipe are pretty much the only ways.

I do not use 10bit encoders for now but thanks for the tip ;)
