TIP - Maintaining audio sync in multicam editing

Saw a post in another topic about problems maintaining audio sync in multicam editing.

I had a HELLACIOUS problem with in my first multicam project.

My error?

Not making sure that video and audio events on the timeline were UNLOCKED.

So, when I dragged video event edges to create auto crossfaces, I was accidentally dragging audio audio events around as well.

Later when looking at the audio events, and finding undesired audio crossfades, I manually uncrossfaded them, and thus leaving many audio clips out of position.

SHEESH! Took DAYS to resolve!

Cheers,

XOG

XOG, check out Excalibur for multi-cam editing and syncing. As a bonus, several other tools are also included including one that will take a selected audio and video clip and re-sync them.

Here's a tip that I find very useful. Immediately after capture, I establish sync with my 3 or 4 different angles. Each camera to its own track. Save the .veg, then render each track to new .avi files. This gives each file the same time stamp (starting at 00:00:00:00). It does nothing to the video, thus no quality loss. Then if you accidentally move a clip while editing, it is very easy to re-establish sync. Just zoom all the way in and line up the numbers!

This method does require a heap of hard drive but after you have rendered your new tracks with matching timecode, you can delete the originals.

thats how I usually do it, I have done 5 or 6 cameras this way.
