Eliminating random dupe frames

[LoKi128]

I have a clip a friend of mine sent me... it has a whole bunch of dupe frames. I tried using decimate, but the thing is that the dupes don't occur in cycles all the time.

Most of they time, I get 7 good frames, then 3 dupes. But sometimes I only get as little as 5 good frames, and then a series of 5 dupes. Tried using decimate(cycle=6, mode=2) and it got rid of a whole bunch, but it is still kinda jittery.

Is there a plugin that will just go thru the whole clip and if it detects a dupe, remove it, no matter where it is? I just started messing around with AviSynth today, so I'm still learning.

Thanks!

This would get you a variable fps movie, which isn't possible.

Decimate is probably the only way to go. You could try uploading a critical section of the file somewhere, for us to help you more.

You could also use the Dup-filter - that way the duplicate frames will be exactly the same, and take up almost no space when you compress them.

I've been wondering about how to implement this for some time. Is it possible to set the frame rate and count in the filter's destructor, where we know how many duplicates we have?

@neuron: I'll follow up in development.

It may be necessary to already have that info at open time for Vdub and also during processing to properly interleave audio. Imagine if all the dups were at the end of an 8 hour run.
