Trying to deinterlace and encode to mp4.
Inputting DV50 mov files, but always get a crash with exit status 0. (Other files work fine, Prores, DV25 in mxf wrappers).
Tried multiple files.
Anyone have a clue why or how to fix?
Thanks!

script seems fine on first view, I would guess that the decoder has an issue with the inpu.
=> Does the Vaoursysnteh Preview show an error?

Even running the VapourSynth Viewer, without opening a file, I get an error:
Quote:Failed to open the file C:/Users/USER/AppData/Local/Temp/tempPreviewVapoursynthFile09_13_24_852.vpy.
There is no such file, but also don't know why it's looking for it before I load a video....
Thanks!
No clue how that could happen.
When I start Hybrid and press the Vapoursynth Preview button I get
---------------------------
Info
---------------------------
Current source has no video!
---------------------------
OK
---------------------------
same when I open a source, press the input button to load a new source, don't select a file (thus clearing the source) and then pressing the button.
But unless you try to encode non existing files that probably has nothing to do with the error.
Cu Selur
Ah, I was trying to use the Tools/vsViewer to open (or opening vsViewer.exe directly from the folder).
Using the preview button, the video plays fine. (But I didn't know for sure it was using the VapourSynth Viewer.) Alas, it still does not deinterlace or encode.
It is crashing on the encode step:
09_video CRASHED encoding video to MPEG-4 AVC with x264 (2pass 1st pass)
Thanks!
The Vapoursynth Preview is under Filtering in the right lower corner.
I know where it crashes from the debut output. I crashes when calling:
Code:

x264 returns:
Quote:x264 [error]: could not open input file `-'
y4m [error]: bad sequence header magic
as error message which happens if:
a. there is a problem with the Vapoursynth script
b. the decoder can't access the Vapoursynth script properly (which usually only happens if some over reating virus scanner or similar is actively interfering)
-> I suspect there is an issue with the source filter. Try whether it helps to disable 'Filtering->Vapoursynth->Misc->Source->Prefer LSMASHSource voer LWLibAVSourcec for mp4/mov'.
(jobs&co naturally have to be recreated)
Cu Selur
Ps.: disabling 'Filtering->Vapoursynth->Misc->Source->Prefer LWLibAVSource over FFMpegSource2' might also help.
Deselecting 'Filtering->Vapoursynth->Misc->Source->Prefer LSMASHSource over LWLibAVSourcec for mp4/mov' works!
Is this a good option? I'm assuming LSMASHSource is usually better?
(I think that Windows Security is running its realtime protection, but I can't disable that.)
When I do the VapourSynth Preview with that option selected, I do get an error:
Quote:Failed to evaluate the script:
Python exception: lsmas: failed to get video track.
Traceback (most recent call last):

Thanks much!
Windows Defender should cause no issues.
Qualitywise there should be no difference between the source filters, it's mainly about speed and that some filters do not suppport each content. LSMASHSource is basically a specialized version of LWLibAVSource which is meant to better deal with mov and mp4 files, but depending on the input it might fail. Whenever I find a clear relation I adjust Hybrid to not use LSMASHSource,...
-> if you can share a small sample (a few seconds is enough) I can test it here an when I can reproduce the issue I'll adjust Hybrid to automatically not use LSMASHSource for such content. Till then disabling 'Prefer LSMASHSource over LWLibAVSourcec for mp4/mov' is fine.

Thanks will fix for the next release.
