Quantize to frames

Cooldraft wrote on 10/31/2008, 4:24 PM

I was getting ready to sync these two cameras for multicam and then went to then off quantize to frames but had the thought "that might not be a good idea." Is this thought correct? I would like to turn off quantize to frames so that I can get the cameras dead on.....

only thing you could sync up with QTF off is the audio. but they shouldn't be so far off someone would notice if you used only 1 of the camera's audio: it's be off less then 1 frame.

but I'd say it's a bad idea.

Bad idea indeed. In fact, you *cannot* adjust the video sync at sub-frame levels. Say, for example, that you decide that the second camera's video needs to be moved back 1/4 frame on the timeline so you move it there. Then what happens? When Vegas previews or renders it plays the next frame available at the project's frame rate ... exactly one frame after the last frame of the previous camera. It will not and cannot have that last frame last 3/4 the duration and suddenly play the next frame 1/4 frame early. That would break almost every standard, transfer, and playback system out there.

In agreement with both responses, I would save my project (important!), then only use QTF "off" for aligning the second audio track to the master, assuming the audio wasn't multicam-edited, too.

As Kelly explained, you can't work in anything less than 1-frame increments. The solution is to genlock and timecode sync your cameras during the shoot.

Thank you all, glad I asked!
