IVTCing this Video...

[Alwyn]

Attached is a video that's had a very hard life, finally ending up as a DVD. It appears to have a PPIII pattern. I've tried a default TFM() and TDecimate(), but have occasional ghosting (hand at frame 18, fingers at 46 and 50). Can anybody do any better?

Code I used:

aud=ffaudiosource("H:\VTS_01_1.mpg",track=-1)
vid=ffvideosource("H:\VTS_01_1.mpg", track=-1,  seekmode=1,fpsnum=30000,fpsden=1001)
audiodub(vid,aud)
tfm().tdecimate()

Please ignore the aspect ratio and borders.

Try

LWLibavVideoSource("VTS_01_1.mpg")
QTGMC(preset="fast")
srestore(frate=23.976)

Thanks Sharc, very nice. Big improvement on the TFM version. I "no comprehendi" but it works!

The film source wasn't properly 2:3 telecined but framerate converted by field blending (inserting blended fields), or some weird mix of interlacing, telecine and field blending as I see it. Therefore TFM().TDecimate() can't reverse the odd process.
SRestore needs a few "training" frames at the beginning to lock into the blend pattern.

Another approach using TFM() and SelectEvery():

LWLibavVideoSource("CVTS_01_1.mpg")
TFM()
SelectEvery(5, 0,1,3,4)

Unfortunately, if there are any breaks in the telecine/blending pattern you will have to work in sections.

Sorry for the late reply, thanks Jagabo!
