Prefs: "Do not Quantize to frames . . "

I've noticed this in Options|Preferences|Editing . ..

"Do not quantize to frames for audio-only edits"

Where and why would I want to force this as a Preference? As it says "audio-only edits" - but I suspect this will trip others over - if engaged - is it by default? Yes?

Maybe this is the issue with the other thread today with synch issues? Is this the default option? Seems like it? Hmmmm....

Grazie

This is a great new feature. It means your video clips will be quantized to frames, but your audio clips will not.

I've run into situations in V8 where I needed to move or trim an audio clip in between frames, so I would turn off quantize, but forget to turn it back on before messing up a video clip that needed to be quantized.

Now I just need V9 to run smoothly. :(

Thanks jp. Does this mean that the VIDEO is quantized but NOT the AUDIO?

Grazie

That's it.

Soooo, does this also mean that I could edit a vocal part of a video (interview) and the vocal/voice would also be un-quantized too? See my point here . . ?

Grazie

It says "audio only edits". If your audio is grouped to your video then the QTF setting of the video locks the audio to frame boundaries.

Not certain what'll happen if you Ungroup the two tracks though.

Guess that's correct. However generally audio and video cuts are not coincident and there may be advantages in being able to select "quantize video only". It is common (usual?) for audio cuts to lead the video cut by several frames (obviously sync maintained) and making that audio cut within the space of a frame might be needed. Of course that can be done anyway by disengaging/re-engaging "quantize".

I can see this capability to be very useful in editing music videos like the one I did recently (the Marcin Dylla DVD).

Having to cut the audio with millisecond precision, I was in constant fear of the video not being QTF'ed. I got away with it, but hopefully my next similar project will be more relaxed.

Yes, find myself doing this a lot. However first you have to select Ignore Even Grouping. That'll let you edit the audio separately to the vision but the cuts will still be on frame boundaries. If you need finer edits then you also need to disable QTF.

The best thing about this is that I won't ever have to remember to turn "quantize to frames" back on after turning it off for some audio synching. I've screwed up a few projects like that. Now I'll just be able to leave it on for video and off for audio.

Yes, several opportunities for making an error. Initially I thought V9 was offering a simplified process, but guess it isn't possible.

I should do a search and link a bunch of posts throughout the years, but I'll just state it.

There has been a pretty consistent recommendation that Quantize to Frames be left on for video editing and turned off for audio editing. That is for all versions of Vegas.

By audio editing, the recommendation (as I recall) has been for audio only editing as in making a music CD, for example. Redbook audio compliance requires a 2 second pause between tracks that can easily be thrown off by frame quantization.
It is easy to forget to turn Quantize to Frames on or off so the new preference (I believe) is designed to avoid having to remember once you select it.
