[HELP] Audio is ahead of video for half a second

[Selur]

A single freeze frame would create a 40ms delay not half a second (500ms).
Loading the input file in Hybrid, overwriting the scantype to tff, using QTGMC-Bob I see a small issue with frame 42.
Loading the output file in Hybrid, disabling the overwriting of the scantype to tff I too see a small issue with frame 42.
(Happens with both LWLibAVSource and FFMPEGSource2. And can be somewhat compensated using 'StabilizeIT'.)
In case you have a 64bit vfw decoder for the HuffYUV in your system, you can enable 'Filtering->Vapoursynth->Misc->Source->Prefer AviSource for .avi input' which will tell Hybrid to use AviSource if it finds a 64bit vfw decoder for the content. This was you can test whether it's an issue with the decoder.

I did a quick encode using:

and attached the result. (using QTGMC, AutoWhite, SpotLess, StabilizeIT, FFT3DFilter, mClean)

It still sounds a bit like it might be a playback issue.
AVC 4:2:2 is often not supported by Hardware decoders.

-> I also attached a YUV420 version, does the YUV420 version work better for you?
Do you see the duplicate frame if you open your reencode in Hybrid and check the Vapoursynth preview? (if yes, which frame?)

Ps.: Your system isn't overclocked, is it?
