deinterlacing .vob file via QTGMC-still have blending

[clashradio]

Hello,

I'm somewhat green with AVISynth scripts. I'm struggling to find the best code to deinterlace and upscale a Region 2 dvd to 720p BD delivery. I'm in NTSC-land and working with a European dvd. It's frame rate is 29.97 which I thought was odd. The show was video recorded in Texas, but possibly sourced from PAL.

When I enter SRestore(), the frame rate ends up 25fps and you can definitely see missing frames during fast movement when compared to 50fps. When I use SRestore(50) it looks more smooth, but still shows what I think is called blending? (when the guitarist's hands wrap around the fret board at a fast pace).

I've rendered three different frame rates (25, 50, 59.94) and to my eyes 50 seems to give the least blending. Is there a better way determine what the frame rate should be? I'm basically guessing on the complete script (see below).

Render time is not an issue. Quality is the main concern. I can do any other restoration in my NLE so that's why there aren't any codes for noise removal, sharpening etc.

I couldn't figured out how to Mark In/Out and render a vob file. I thought Direct Stream Copy was how but I could only render in AVI.

Thanks in advance.

a = LWlibavAudioSource("input.vob")
v = LWlibavVideoSource("input.vob")
AudioDub(v,a)
AssumeTFF()
QTGMC(Preset="slower", matchpreset="slower", matchpreset2="slower", sourcematch=3)
SRestore(50)
nnedi3_rpow2(2,cshift="Spline36Resize",fwidth=960, fheight=720)

That's from a 25i to 30i conversion with field blending. You can't restore the 25i without blending because there's too much of it. You might as well leave it as it as 30i or 60p.

When I compare the two renders of 59.94 & 50 frame by frame, I see less blending of the two fields when the camera angle changes when using 50fps. But since this is going to be for BD delivery in the US, then 60p is probably best.

Thanks jababo. You've always helped out and is much appreciated!
