Audio Sync Issue after Deinterlacing and Converting to MP4

[cholla]

I'm believe Sharc gave me the MCDegrainSharp.avsi or a link to it.
Mine is for 32-bit avisynth plus.

It goes in the "plugins+" folder.

So I made a few changes to your script. I could not find the SmoothLevels on the avisynth website so I used SmoothAdjust instead - seems to do the exact same thing. I also set the QTGMC preset to slower. Otherwise I kept everything as per your script and the result is fantastic I must say. Thanks a lot! See video attached.

AviSource("Beethoven_Klaviersonate-short.avi").trim(5,0).converttoYV16(interlaced=true)
assumeTFF()
assumefps(25)
QTGMC(preset="Slower", EdiThreads=2)
crop(12,0,-12,-8)
SmoothAdjust_SmoothLevels(16,1.0,235,0,235)
bilinearresize(width/2,height).bicubicresize(width,height)
MCDegrainSharp()
converttoYV12()
#now encode x264 using -SAR 12/11
Prefetch(2)

Use AviSource() for .avi files, not FFMPEGSource2

Eventualy use the original audio (which is untouched anyhow) in the final output, with AudioDub() command

ffms2 works great with DV-AVI. Better than LibavVideoSource, but I don't remember what was wrong with the latter.

Not as good as installing a DV codec and using AviSource() in my experience

As you can see from this thread -- not necessarily.
And I've already converted a lot of DV-AVI tapes using ffms2.

Just to mention a difference: For no obvious reason your variant (left) denoises more but blurs more than mine (right) of post#29. See for example the plants in the background. The compromise is a matter of personal preference though, not to argue.

Edit: I see you were using a different (blurrier?) source file. That may be the reason for the difference in sharpness/details.

Where did you see in this thread that ffms2 is better? Did I miss something?

Sure. I just dislike its many versions around, leading different results.
