Vegas Duplicating Frames

[darmanb]

Please help!

I am working on a 3 minute 24P project in Vegas 5.
After rendering to an uncompressed avi file, I notice that on some parts of rendered (new) clip a lot of frames have been duplicated (for example: 2 identical frames are in sequence, then next 3 frames are good then 2 frames are the same etc). On these parts of the clip, footage looks unsmooth and not good.

What am I doing wrong?
In rendering window I set it to: avi, uncompressed, progressive, best quality, NTSC 24P.

I thought this had something to do with keyframe interpolation in pan-crop window (I have a lot of keyframe animation in this project) - so I set the smoothnes value to "0" instead of "1" (by default).
Nothing changed!!!

I also tried turning off the "interleave" function in rendering window.
No change also!!!

I would really appreciate your help with this one.

Thanks

What frame rate did you pick? Sounds like it's inserting 2:3 pulldown, so you must be rendering at 29.97.

My project properties are NTSC 24P (23,976 IVTC) with Pulldown Removal "on". I finish my transitions, effects etc., then "render as" - windows avi, uncompressed, best, size: ntsc dv, field order "none - progressive", codec - uncompressed.

When I import uncompressed avi file into this project, and double check with scrolling frame by frame on a timeline - it has duplicate frames.

But what's your frame rate when you render uncompressed? You can check that in your render settings.

Oh. The frame rate in render window is 23,976 IVTC (same as project).

did you change the speed ( slo-mo or fast mo) of those sections ?

 

[darmanb]

For some of the video events, yes I did.
But I also went in their properties/switches and changed sampling to "disable resample".
