x264 encoding error.

[Selur]

PS.: And maybe a feature request worth thinking, related to this kind of issues (unless there already is something like it?):
"Retry CRASHED jobs X times" and/or "Continue to other WAITING jobs after a job has CRASHED", as for some reason the other jobs in the list remain WAITING.

The number of parallel jobs is 1, so if that one crashes, Hybrid stops.
"Retry CRASHED jobs X times" that sounds like insanity.
"Continue to other WAITING jobs after a job has CRASHED", that could make sense, but since a crash often has a reason that could potentially influence other jobs too, I'm not going to implement it.

Looking at the debug output:

looks fine to me, source is trimmed to 27977 frames and boobed, so the output should be 55954 frames.
The decoder call:

"C:\Program Files\Hybrid\64bit\Vapoursynth\vspipe.exe" "C:\Users\hjatsu\AppData\Local\Temp\encodingTempSynthSkript_2024-08-15@21_47_56_3910_0.vpy" - -c y4m

looks fine.
then encoding call:

"C:\Program Files\Hybrid\64bit\x264.exe" --preset veryslow --crf 14.50 --profile high --level 5.1 --sync-lookahead 120 --rc-lookahead 120 --no-fast-pskip --vbv-maxrate 300000 --vbv-bufsize 300000 --deadzone-inter 6 --deadzone-intra 6 --sar 16:15 --non-deterministic --range tv --colormatrix bt470bg --demuxer y4m --input-range tv --fps 50/1 --output-depth 8 --output "C:\Users\hjatsu\AppData\Local\Temp\2024-08-15@21_47_56_3910_06.264" -

looks fine and starts without a problem.
Encoding looks fine:

But then the decoder crashes " Helper(1) finished with exitCode: -1073741819 and exitStatus: 1"
-1073741819 indicates an access violation in the helper, so somewhere in the Vapoursynth processing.
This is usually caused by one of these things:

• a glitch in the source => check whether you can navigate in the Vapoursynth Preview around frame 55698.
  
• heat issues
  
• memory issues
  
• some driver issues (unlikely since it worked for 55698 frames)
  
• overclocking of cpu/gpu/ram (yes, even when every other test seems fine; encoding and intense filtering is really sensitive)
  
• a bug in a filter (unlikely since it worked for 55698 frames)
  
• some antivirus tool (or the os) interfering (especially mcafee and nortons live scanning stuff can cause problems)
  
• runnning out of ram (there isn't always an out-of-memory error is memory gets spars)
