New placement of vsViever Auto refresh button looks great!

What does the Vapoursynth script look like?
Just tried with a random source and had no problem.

Seems ResampleHQ resizer gives error only when used deinterlacer.
No error if i use progressive source.

[Selur]

I can reproduce this.
Seems like a problem with the imwri filter.

[logo, alpha] = core.imwri.Read(filename="/Users/aaa/Desktop/No name.png", alpha=True)
ValueError: not enough values to unpack (expected 2, got 1)

this happens if no alpha channel is returned.
-> added a post over at doom9 in the Vapoursynth thread (https://forum.doom9.org/showthread.php?p...ost1956378) since the filter is maintained by myrsloik.

about ResampleHQ: Try whether adding "clip = core.std.SetFieldBased(clip, 0)" before the resampleHQ line helps.
-> forget that, I overlooked the line, it's already there.

works fine here,... no clue what's causing the issue.

may be a new fmtconv is needed? Will try to look at it on Wendsday after work. No time tomorrow.
Going to bed now.

So i checked all filters for vsViewer errors. Seems all works same as before.

KNLMeansCL produce same artifacts as before. I didn't touch other KNLMeansCL settings to check if it still produce kernel panic.

Also same as before i used MVTools v21. As i noticed earlier in R54 and earlier VS versions MVTools v22 and v23 produce error on render "crashed: Helper1, exitCode: 11"
I didn't check MVTools v22 and v23 with R57 yet, but guess it will produce the same error.

ResampleHQ resizer gives error only when used deinterlacer.
No error if i use progressive source.
Maybe some conflict with resize settings in Hybrid? I will send you a debug.

[Selur]

Strange mvtools is used in tons of scripts. -> I doubt the issue is with mvtools otherwise preview wouldn't work with a ton of the scripts.
Can't check about KNLMeansCL due to lack of gpu support in my vm.

-> will look into the mvtools and resamplehq problem if you share a separate debug output for each.
(got no issues on Windows, so this might be an issue with the libraries)

Seems no more error with MVtools-v23. (it happened when use QTGMC preset "Placebo" in Hybrid. Render started, but after some short time it stopped with error. "crashed: Helper1, exitCode: 11") Problem was reported 15th August 2020 http://forum.doom9.net/showthread.php?s=...ost1921113 and also it was reported earlier by other people few times. From that time i only used MVtools-v21. As i remember last time i tested MVtools-v23 with R53 and it give me same error. So i have no idea if problem fix was in newer Hybrid or in newer Vapoursynth version.

[Selur]

What does "after some short time" mean? 1min 20min 50min ?
That sounds more like a memory, heat, problem, but could also be a bug triggered on your system.
Atm. I see no way to reproduce this.
-> can't reproduce this here. (QTGMC Placebo doesn't seem to crash in my VM, I let it run for 30min)
Also you might want to report to https://github.com/dubhater/vapoursynth-mvtools with details about your cpu&co.
