How to move video freely not frame-by-frame

Is it possible to move video and audio freely on a timeline, not frame-by-frame? I need to sync video and audio from various devices. It is not possible if I'm not able to move the video freely.
I believe there was such option, but now I can't find it.

OK. Problem solved. Alt+F8

Your video MUST be synced to frame boundaries using "Quantize to Frames" and Snapping "On" before placing video on the timeline. The result of not doing so can be black or random frames in the render.

Once done, the audio can be Ungrouped, and QTF temporarily disabled to freely drag the audio around the timeline. This is how sync is achieved. The smallest logical unit of video placement is one frame.

Hope that helps.

musicvid10, excuse me for butting in here but how to you quantize to frames before placing video on the timeline?

Make sure Quantize to Frames is already on before putting the clip on the timeline, and Vegas aligns it for you.

Of course, this assumes that the frame rate of the clip matches the frame rate of the project. Further, if you're trying to sync material from different sources and they have mismatched frame rates then you've got a bunch of other issues to worry about.

Thank you for your advice. I was planning to unsyncronise the video track.
I have a multicam shots. The cameras were not synchronised using timecode. Just two separate shots of the same object. Of course framerate was the same on the both cameras - 25fps. In this situation there is a effect of unsynchronisation becouse the frames do not start and do no end at the exatctly the same time.
Now I will sync all the video tracks quantization on. And then I will unsynchronise and move audio clip to make it sound well with both tracks.

The maximum possible error for unsynced cameras is +/- 1/2 frame relative to reference, and that can't be improved upon, nor is it evident to viewers. To be clear, QTF and snapping should be turned On before adding any media. Those controls offer no post-corrective action in themselves, but there are scripts that will do that.

If you need more control, the solution is free-run timebase sync with genlock, meaning the cameras are daisy-chained with a cable.

PluralEyes is a huge timesaver for syncing audio tracks. Having done some multicam projects with up to five audio submixes, I can;t imagine doing it by hand again.
