[RESOLVED] Method/filter to remove hard-coded repeat frames

Post by SeeMoreDigital »

Hi all,

I've probably missed something obvious but is there a method or filter that will enable me to remove "hard coded" repeat/duplicate frames from 50fps sources. Such as can be found in this sample: http://www.mediafire.com/?69xxlsttb36759g


Cheers

The obvious thing is Decimate(2) or SelectEven() in Avisynth.

Are you looking for a VirtalDub filter for that?

Ideally yes...

EDIT: Something that offers simplified options along the same lines as the IVTC plug-in would be handy.

Use this:

Video/Frame rate.../Frame rate conversion/Process every other frame (decimate by 2)

The latest filter SDK supports dropping frames so it would be possible now to make an adaptive Decimate filter, but the above built-in function should be fine for this application.

I actually tried the "Process every other frame (decimate by 2)" option but it does not seem to work with v1.10.0 (Build 33848). Are you able to make it work?

No I haven't tried 1.10.0, which is still "experimental". I suggest that you followup at the VirtualDub forum if you have found something broken in 1.10.0.

Bummer...

I've just tried VirtualDub versions 1.9.9, 1.9.10 and 1.9.11 and their decimate options don't seem to work with the sample I provided either!

How are you loading that sample into VirtualDub?

I'm dragging and dropping the elementary .M2V file directly into VirtualDub.

The .M2V file opens okay and VirtualDub correctly recognises the files properties. I'm at a loss!

You must be using fccHandler's MPEG2 plugin.

I loaded it in 1.9.11 and set decimate by 2. I did Save as AVI and reloaded the resulting AVI. It was properly decimated.

The decimation does not take effect on preview, only on Save as AVI.

I see... I was not expecting the decimate option to function like that.

I am however happy to confirm that the repeat/duplicate frames have been dropped on the "save.AVI" output.


Thanks for your help
