Problem with Avisynth - frames

[Colek]

Hello,

I am having problems with my Avisynth script or maybe the encoding - I am not sure at all and I don't even know how to describe the issue, that's why I am including sample below.

I am using VirtualDub x86 1.10.4 with lastest Avisynth MT. I am encoding with Lagarith's codec with multithreading, prevented umsampling and RGB mode.

Here is the script and here is the sample of the issue (Youtube mirror).

I would be thankful for your help on this issue.

Are you talking about the jerky out of order frames? Try SetMtMode(5,1) instead of 3,4. If that works try this:

SetMTMode(5, 4)
SetMemoryMax(1000)
AviSource("Upscaled 720p WEB-DL.avi")
grain = AviSource("J:\Projekty\Island of Fire\35mm Grainplate.avi").loop(framecount(last))
SetMtMode(2)
MosquitoNR()
QTGMC(InputType=1, Preset="Fast", EZDenoise=3.0, Sharpness=1.1)
Overlay(last,grain,mode="SoftLight",opacity=0.6)

Thanks for help!

The problem was with QTGMC filter, so I simply used different one and it works just fine now

Setting MTMode to 5,1 helped it as well, but it would take 4x as much time to render. So I decided to use power of my GPU and used OpenCL denoiser.

The problem wasn't with QTGMC() directly. But when using QTGMC() frames were requested from AviSource() out of order. That was causing AviSource() to deliver the wrong frame on occasion -- probably because you have h.264 in the AVI file. VFW's one-in-one-out model is not good at retrieving the correct frame from codecs that store frames out of order.

You could try using ffVideoSource or DirectShowSource() instead, though the latter will probably screw up even more.
