Forcing Vegas to do 24P PullDown Removal ?

TheDingo wrote on 10/19/2009, 4:18 PM
I am trying to import some .M2TS files shot with a Canon HG21 camera into a Vegas 1080 24P timeline, but I can't get Vegas to recognize that it needs to do the pulldown removal for the clips I am editing.

The option flag has been checked for "Allow pulldown removal when opening 24P DV", but Vegas is not doing any pulldown removal at all.

The clip properties in Vegas show the clips as 1920x1080 29.970 fps, and I can see the pulldown ghost images on the timeline when anything in the frame moves quickly.

How can I fix this pulldown problem ?

Thanks in advance.

You need a program that will detect and remove pulldown. Cineform has products that do this as do some others. Your clip is technically 29.97 but if you go through it frame by frame you will find duplicate frames added to the 23.98 content in order to make it 29.97 fps. I didn't notice this at first when I first used the 24p mode. It was supposed to look different and it did, I just didn't realize what I was seeing till was stepping through something frame by frame.

I think it is actually duplicate fields, not frames. AFIK, Vegas does not have any facility to remove pulldown from 29.97 video in order to recover the original 23.976 progressive footage. Cineform can do this, and there are some free plugins for AVISynth which do it extremely well.

You ALWAYS want to edit and encode using the native 24p footage. Encoding 29.97 which includes pulldown results in very poor results because the encoder goes nuts (technical term) when it tries to make sense of complete absence of motion between some fields, but not others.

Can't you manually remove the pulldown? (This would be a tedious manual process though. I believe that Cineform can do it in an automated fashion.)

In Project Media, right click the clip and go into File Format properties.
Enable pulldown removal.
You'll have to figure out which of the 5 options is correct....
