x264 keeps crashing, here's error messages and logs

[florinandrei]

Trying to encode a video, using the AVCHD (DVD5/9) preset in MeGUI, mode Automated 2pass, 5885 kb/s. It seems to always crash at the same point, about 40% into the first pass. Source is 1080p30 VC-1. x264 version according to MeGUI: 1649

Windows error message:

Let me know if I need to do anything to help you troubleshoot it.

[Sharktooth]

the x264 crash is probably due to an avisynth crash (due to a plugin or some other factor). post your avs script.

[kemuri-_9]

since the scenario is
A) an invalid access exception
B) you have a 1080p source
C) are using a 32bit x264 with avisynth
you're probably running out of memory with hitting the 2GB process limit.

[florinandrei]

the x264 crash is probably due to an avisynth crash (due to a plugin or some other factor). post your avs script.

Here it is:

DirectShowSource("C:\hd\universe\video.mkv", fps=29.970, audio=false, convertfps=true)
#deinterlace
#crop
#resize
#denoise

you're probably running out of memory with hitting the 2GB process limit.

Interesting. I've been doing this for quite some time and:


in the overwhelming majority of cases it's fine
on those very rare occasions when it does crash, trying again usually solves it


But this is different for some reason.

What can I do to troubleshoot it? I could try a few different things to get more info out of it, just let me know what should I try.

I used x264 32bit 1804 and memory using over 2GB is All Right complete.
