QTGMC Deinterlacing Script (v3.384) - Page 28

heartagram · 5th June 2018, 11:25

can you suggest me any free avi video cutter to give you the sample!?

LigH · 5th June 2018, 11:41

VirtualDub2; select a range from one keyframe to another, to possibly avoid recompresion (using "Video - Direct Stream Copy" mode). BTW, which video format is contained? (File - Information)

Music Fan · 5th June 2018, 11:45

Or MKVMerge or tsMuxer.

avi format. the videos are not captured by me from VHS, and there is something wrong with them....i just want to encode them, to fix the picture if i can and make them with smaller size.

VirtualDubMod 1.5.10.2 says:

Code:

VirtualDub cannot decode 4:2:2 Motion JPEG frames with image widths or heights  that are not multiples by 16.

So we have also wrong resolution i guess..

EDIT:
video sample 3sec

VirtualDub2 is not VirtualDubMod...
_

Frequently asked question: smart deinterlacers with motion prediction (like QTGMC) need steady and continuous motion; cartoons have discrete motion (a.k.a. "Stop Motion"). QTGMC is not suitable for this kind of material because it will predict motion wrong.

Well, in this special case, one frame would have told us enough... it just had to be visible.

Unfortunately, I don't know a "cartoon-safe" deinterlacer right now...

i got it thanks...

I believe cartoons may get an advantage from a specific kind of decimation (forcing the TV-common frame rates down to cartoon-original low frame rates by combining and averaging the most similar fields). Such issues will have their own topics already.

That's not a video.

And it's not field blended, only phase shifted. You could try this:

AssumeTFF()
tdeintted = QTGMC(FPSDivisor=2)#or a different deinterlacer, if you prefer
tfm(CThresh=5,clip2=tdeintted)

i did you scipt and here is the result -

- source

-with tfm, assumetff,tdeint

LigH · 6th June 2018, 10:39

Looks like this video was scaled vertically before trying to deinterlace. That's deadly.

Please post the complete script. I saw nothing like that when using this script:

AVISource("balu-clips-no-deinterlace.avi")
AssumeTFF()
tdeintted = QTGMC(FPSDivisor=2)
tfm(CThresh=5,clip2=tdeintted)
return last

your sample looks great!

This is the script i tried

Code:

LoadPlugin("C:\Program Files (x86)\AviSynth\plugins\TIVTC\x86\TIVTC.dll")
DirectShowSource("D:\anime\A Bad Reflection on You 2.avi") # 
Crop(20, 2, -22, -10).LanczosResize(720,576)

AssumeTFF()
tdeintted = QTGMC(FPSDivisor=2)
tfm(CThresh=5,clip2=tdeintted)
return last

it seems that im doing something wrong with the crop&resize function. Should i leave the resolution to 720x540?

Yes. Never resize before IVTC / deinterlacing. You'll get extremely bad results as you've now experienced.

heartagram · 6th June 2018, 20:21

thanks

this seems to work fine now. what do you think? i had to add converttorgb32 because there was issue with the colors... in that case crop function seems to be the problem, adding converttorgb32 fix the problem. i dont know if this is ok.

Code:

LoadPlugin("C:\Program Files (x86)\AviSynth\plugins\TIVTC\x86\TIVTC.dll")
DirectShowSource("D:\anime\A Bad Reflection on You 2.avi") # 

AssumeTFF()
tdeintted = QTGMC(FPSDivisor=2)
tfm(CThresh=5,clip2=tdeintted)
Crop(20, 2, -22, -10).LanczosResize(720,576)
ConverttoRgb32
return last

neah...my mistake...removed converttorgb line...everything looks fine.

manono · 7th June 2018, 19:56

Don't use DirectShowSource as your source filter if you can avoid it. In your case, the built-in AviSource is much better.

Why was the video 720x540 if the source was a VHS tape? Why wasn't it captured as 720x576 to begin with? I think you said earlier you didn't capture the tape? If you know the capper, you should advise him.

By cropping and resizing as you did (for DVD, I presume?), you've changed the aspect ratio. Maybe you don't consider that a problem, not sure.

heartagram · 7th June 2018, 20:21

AviSource gives an error. something like "Avisource couldnt locate a decompressor for fourcc mjpg". (using virtualdubmod 1.5.10 to load and preview)
I'll check google/doom9 and try to solve it.

Yeah i met the guy on the internet, we shared some anime videos at that time. I told him that this captures could be done much better. ALso i asked him if its possible to send me the tapes because I had VHS recorder with internal TBC plus i was looking to buy external tbc, but he refused my offer...

No i'm not planning to make dvd. Some of the series has 2gb filesize... as i said i'll just try to make them smaller and keep the quality or make it better! Thanks to you it will work out!

btw should i leave it 720x540? I was thinking it is good idea to fix the resolution, nothing more.... ALso i'm using Megui loaded with x264 profiles, there is anime toons profile which im planing to give a try! any ideas for the encoding option?

LigH · 7th June 2018, 21:40

Frequently asked question all over the internet: "couldn't locate a decompressor for FourCC 'MJPG'" => you have to install an MJPG VfW codec, e.g. Cedocida.

Cedocida is a DV codec. Wrong example.

LigH · 7th June 2018, 22:13

Sorry, I had in mind that it is a combined codec... sieve mind.

Well, a quite good and free MJPG VfW codec would be part of ffvfw in ffdshow; but in general, ffdshow is obsolete as DirectShow filters. Maybe via custom installation.
