Remove every 5th frame?

[Morg]

Hi,

I have a movie encoded as 25 fps progressive. Watching is unbearable, it's so jumpy. When looking closer (with VirtualDub) and checking framewise, I found every 4th frame is doubled, so the movie stutters on every 4th frame (displaying it twice).

Is there any way to compensate for/remove it? And/or has anybody any idea, why the movie was encoded this way?

Regards,

Sebastian

I have a movie encoded as 25 fps progressive...has anybody any idea, why the movie was encoded this way?(cough,cough) Rule 6?

Ehhh, may I ask why?? He could be talking about how it was encoded on the DVD, which is no rule 6 violation!

You can try with the Avisynth filter:

SelectEvery(clip,5,0,1,2,3)

0.1.2.3 ... 5.6.7.8 ... 10.11.12.13 ....

But if for some reason there's a pattern break, selectevery won't work. That's why I suggested a simple decimate from the Decomb package (could also use tdecimate from the TIVTC package).

@Morg

What DVD is it? Title and region?

I own an original DVD, which is not copy protected (it's an orchestral concert). I also have a converted AVI movie of the DVD, of which I don't know any more when and how it was converted. I hope this covers rule 6 - anyway, no offence meant.

@Morg: neuron2 asks what title and what region it is and the reason is simple: if someone knows this particular release (whatever it is), they might be able to tell you: this is a release with blended fields, this is a release with PAL speed up only etc.

I also have a converted AVI movie of the DVD, of which I don't know any more when and how it was convertedJust make a new conversion from the original DVD - It will undoubtedly be of higher quality than an "adjusted" .AVI and you'll no longer have to wonder why, or how, you originally created an .AVI with "every 4th frame is doubled"...
