QTGMC won't open a video

[Alwyn]

I tried and then I cried. I've had (another) crack at getting QTGMC up and running but have failed and I would be grateful for any help you can give me.

I'm on a Win 10 machine, and I've been following Andrew's Blog guide

I got AVISynth (linked from his blog) from here: https://github.com/AviSynth/AviSynthPlus/releases

I tripped up badly on the various NNEDI3 versions and the FFTW files into Sys32 and WOW64, but have eventually got AVISynth installed and working.

For 64 bit, the infotool shows this (the 32 bit report shows no issues at all):

I have no idea how to correct the two errors.

My plugins 64+ folder looks like this:

I can open a video in VDub using a simple "AVISource=" command with no problems.

But when I try to open a video with QTGMC with this:

AviSource("710USB Kempsey.avi")
QTGMC(Preset="Fast")
SelectEven()

I get varying error messages from VDub, as follows:

VDub 1.10.4:

VDub 2 32bit:

and VDub 2 64bit:

Any help will be greatly appreciated.

Thanks, Al

Seeing that you use 64bit Avisynth you need to use 64bit VirtualDub(2).
The problem you encounter happens since you try to feed QTGMC with content that uses a color space which QTGMC does not support, adding:

ConvertToYV24(interlaced=true, matrix="XXX")

with XXX one of these:

• "Rec601" : Uses Rec.601 coefficients; scale full range [0d..255d] RGB ↔ TV range [16d..235d] YUV.
• "Rec709" : Uses Rec.709 (HD) coefficients; scale full range RGB ↔ TV range YUV.
• "Rec2020" : Uses Rec.2020 (UHD) coefficients; scale full range RGB ↔ TV range YUV. AVS+
• "PC.601" : Uses Rec.601 coefficients; keep range unchanged.
• "PC.709" : Uses Rec.709 (HD) coefficients; keep range unchanged.

before the QTGMC call should help.

Selur, success! Thanks very much, that worked.

A question on that though, I have been capturing my VHS in YUY2 (Lagarith). Should I perhaps be capturing in some other colour format (it appears that Lagarith can only capture up to YV16?).

Do you have any thoughts on my two AVISynthInfo Tool errors:

[Plugin errors/warnings]
__________________________________________________ ______________________________

Function duplicates:

"undefined" : "[InternalFunction]"
"Undefined" : "C:\Program Files (x86)\AviSynth+\plugins64+\Zs_RF_Shared.avsi"

or can I ignore them (everything is running OK by the looks of it).

[Selur]

"undefined" : "[InternalFunction]"

-> no clue

"Undefined" : "C:\Program Files (x86)\AviSynth+\plugins64+\Zs_RF_Shared.avsi"

File probably doesn't exist, probably should come from: https://github.com/realfinder/AVS-Stuff

Cu Selur

The "Undefined" warnings are due to the fact that the AviSynth core defines it first, and it is redefined in Zs_RF_Shared.avsi for its special needs. No reason to worry.

[Alwyn]

Thank you @LigH.de.

I shall put that message from AVISynth Info on my Ignore list.

To answer my own question, LAGS YUY2 is ok for AVISynth; the file that wouldn't open had already been re-encoded into something else.

[Sach3932]

Can anyone help me I don't understand whether my QTGMC AviSynth+ is working or not in Windows 11 because i don't see any difference in the video using QTGMC.

[LigH.de]

If you don't see any difference, then maybe your original video was not interlaced at all?

How shall we know if we don't see your video before and after filtering, so we can't compare?

[Sach3932]

Do you have any sample video which is interlaced so i can give try in my system.
