Avisynth - fix/decimate another bad DVD.

[maudit]

Hi, I've a PAL DVD that it seems to have 1 double frame every 24 frames.
I've tried this command:

TDecimate(Cycle=24, CycleR=1)

But it is not correct, what command and parameters should I use with this 1m sample?

edit: adding "Mode=7", somehow makes the sync correct, anyway it does not delete the duplicates but others.

If the repeated frame is always in the same place, you can use SelectEvery instead.

SelectEvery(which parameters)?

It's 1 in 25, not 24

TDecimate(cycler=1, cycle=25)

thx, but I've already tried 25,1 and I don't see duplicates, but the sync with the BD is lost. about 145 frames.
I now upload a new sample starting from the begin.

TDecimate(cycler=1, cycle=25) gives you 24/1 FPS . If your BD 24/1 FPS , or 24000/ 1001 (ie. "23.976") ?

yes I see it gives 24p, anyway
I've noticed the DVD is labeled as CUSTOM, so I think the audio has been probably manipulated.
The DVD has no ENG audio, chapters every 10min, and first of all, If I mux the audio with the BD(24000/1001), it matches.
I don't even understand how, as the VOB is at 25fps.

I have no idea from where the audio come from, maybe from a VHS or DVB, but it's the only one I have.
so, sorry for the useless thread, I will mux it as it is even if the DVD audio is crap.

SelectEvery(which parameters)?

SelectEvery(clip, 25, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 17, 18, 19, 20, 21, 22, 23, 24)

would remove frame 16 from each 25 frame large chunk,...
see: http://avisynth.nl/index.php/Select#SelectEvery
=> you need to adjust the call to leave out the frames it should remove. (like I wrote this only makes sense if it's a fixed pattern)

Why would you expect the DVD and BD to match? In my experience that's rarely the case. Different speeds, different cuts, different studio logos, etc.

By the way, TDecimate() and SelectEvery() change the frame rate to compensate for the number of frames removed. So the running time is the same as the original.
