Editing GoPro 1080P 60 in 1080P 30 timeline VP10

kplo wrote on 11/14/2014, 4:20 PM

In a 1080P 30 project, if I drop a GoPro 108060p file on the timeline, will Vegas automatically use every other frame and play back at the correct speed?
And/or should I set the undersample rate to .500 (1/2) in the media property tab?
The output file in either case will be rendered to the Cineform codec at 30P.

Thanks for your advice.

Setting the undersample rate to .5 is what you want, otherwise, if you just drop 60p footage into a 30p timeline, Vegas will smart resample the footage, each 30p frame will be a blend of two 60p frames and that isn't what you usually want.

If you disable smart resample, Vegas will just drop every alternate frame from the 60p footage.

That part of the beauty of Vegas, there is often more than one way to accomplish something, either set the undersample rate to .5 or turn of smart resampling, both will work.

Thank you both.
I'm thinking that checking "do not resample" might take a bit less processing power than setting the undersample rate and letting Vegas "smart resample". Or not
Best,

This topic makes me wonder if I got this correctly... if I shoot at 60p for slow motion, I'd want Vegas to use every frame but at 30p framerate, right? Wouldthat mean using a 30p timeline/project setting AND turn off smart resample?

I understood that the previous posts involved retaining the original playback speed. If you want to play a 60p video at half speed as a 30p video, use the old control-drag trick:

Set project Properties to 60fps. Change the timeline ruler to Absolute Frames. Note exactly how many frames long your movie is. Change Properties to 30fps. Ctl+Drag the end of the movie so it is now the exact same number of frames long.

Voila!

Or just set project property to 30p and rate to .5 in event properties, and click drag the right edge to its new length.

If the OP wants slow motion from 60p in a 30p timeline I would do as TeeTime suggests.

When you set the playback rate to .5 and drag the video to its new doubled length it will snap to the new length indicated by a small gray triangle.

Thanks for the answers!
