[HELP] Output to mp4/x264 very slow
Is there something I can do to speed the encoder up? It seems to get to 100%, then starts again. So far it has taken over 24 hours, now it says there's another 62 hours remaining.

If I set the x264 preset to "fast" or "faster" would that help, without reducing the quality too much? It is currently set to "none", which I guess is "medium" by default?
Since you did not care to share what settings you are using, it's hard to tell what changes will speed up things.
Especially without knowing the bitrate/crf and the content type you use. With a really high bit rate (compored to the content) faster settings don't hurt, with low bit rates they do. Wink
The defaults Hybrid uses are not the same as the 'medium' defaults of x264.

I just noticed this: interlaced=False, interlacedd=False)

Could this be causing any issues?
Quote:interlaced=False, interlacedd=False
first specifies input, the other output interlaced handling

You didn't share your encoding settings, but you want advice on your encoding settings.
If you used for example 2-pass encoding, this could be normal seeing your script.
Since your aim for YUV420P8 output, enabling 'Filtering->Vapoursynth->Misc->Source->Convert to target color space after source filter' might speed up the Vapoursynth script.
