M2V file encoding fails with an error
Hello Selur,

Current version Hybrid 2023.01.22.1

M2V file (extracted from DVD) encoding fails with an error. There were no errors in the previous version

If M2V is muxing in MKVToolNix as MKV and start converting with my settings - all is wel

looks fine.
Hybrid stops, since the output file is 0 bytes.

Does the Avisynth Preview work?

My guess atm. is that this is related to Avisynth and SVP.
Reinstalling the graphic card drivers might help. (using Vapoursynth instead of Avisynth probably fixes the issue too)

As a side note: That script seems wrong.
If the source is interlaced (and not telecined like most commercial DVDs) using QTGMC with Bob turned on would be the better approach.
If the source is telecined then using QTGMC is the wrong choice and TIVTC or Decomb should be used for TIVTC, then SVP makes sense.

Cu Selur
Okay, seems like the switch to Qt 6.4.2 broke Avisynth -> use Vapoursynth instead until I figure out what's causing the issue.

Crashed after warnings

if placed in a container mkv also shows an error, but the preview works and converting.
Yeah, seems like I overlooked something there and there is some issue with Qt.
-> I'll probably fix the error there and will upload a new version tomorrow. (which will use an older Qt version for the Avisynth related tools)

Cu Selur
Please, redownload Hybrid_2023.01.22.1_SETUP from
test both preview and encoding and let me know whether it works now.

Cu Selur

Ps.: Also please try whether it works when using Vapoursynth.
Not working Avisynth after redownload.

Vapoursynth - working
Strange, works fine here.
(just tested it)
Does the Avisynth Preview work?
=> Share a debug output.

Cu Selur
Might have found an issue. Seems like 32bit Avisynth uses an of DGDecode version.
(couldn't reproduce the issue since I use Avisynth 64bit)
-> send you a link to a dev version where I updated the source filter in the 32bit folder.

Cu Selur
In the test version, Avisynth does not work.

Vapoursynth - working.

To MKV Avisynth Preview does not work but encoding is successful.

Selur, is there a difference in processing for MKV and M2V ?
