Getting rid of copyframes for true VFR?

[slavik]

I have a clip that was recorded at 120fps (119.88 to be exact) and has many duped frames (sometimes there are single frame parts that are true 119.88fps)

I was wondering if there is a way to remove all duplicate frames and create a vfr film with only the unique frames. (according to my own C program, the source I have has only 21.43% of unique frames).

EDIT: just found MultiDecimate. Please delete/lock this thread.

There are a tool which named "vfrtool" in this forum could finds the true frame and writes files for multidecimate, and writes a timecode text for vfr-mkv. You should search in forum. Goodluck.

I found and used it, but this time I need it for AVI.

Use FDecimate()


From Donald's web page (http://neuron2.net/):
"Fourth, sometimes clips are rendered at 120 fps to properly present hybrids of film and video. if we wish to return to normal frame rates, we need to remove multiple duplicates.

The FDecimate() filter helps in these situations. An earlier filter, MultiDecimate(), also attempted to help but it is a two-pass implementation that requires an additional external program, and is therefore cumbersome. It also could produce audio desynchronization if not used very carefully. I consider FDecimate() to be a superior approach."

wolfsoft - I've not been able to find the tool (vfrtool) you mention - can you please post a link?

I have to try it myself too.

I wonder if there's a tool to remove all dups and turn it into a true 6/8/12fps-VFR clip....
since vfrtool is only able to remove N-vops inserted by the 120fps-tools if I remember it correctly...

Never tried it myself, so I can't help you any further.

No, that's false. Simply read my second link. It works, since i checked it.

[darkavatar1470]

I mean if I feed some tool regular 24fps anime, (or any FPS) the tool should drop all dups (8fps low-mo , Stills & ect.), and give a working timecode file for mkv muxing...

@Wilbert:
sorry, I read about that before, so I didn't notice he updated to make it easier....
I'll find some time to try it myself...

I'd be interested in that too, but it may only be easy to do with modern digitally-rendered anime, as with the filmed stuff you're still going to get noise and camera movement at 24fps.

remux the .avi to .mp4 with mp4box and it will automatically drop the n-vops (copyframes) during muxing and will create a variable framerate stream instead

[Wilbert]

bond, i don't think the clips here have n-vops.
