Locking off video track

Michael Robotham · Post by **Michael Robotham** » Thu Sep 28, 2006 9:53 pm

Getting to like VS10+ more and more but have two questions:
1. Having split the audio track, can I lock off the video track and then run the audio track on it's own?
2. If I can do this, can I then use the time code readings on both the video and audio tracks to restore sync?

Are you saying that your audio and video are out of synch?
If so a couple of posts for you to peruse:

Steve, I'm a little annoyed with myself for sending in that posting.

To clarify: I am putting together a wedding that was shot by three different people and is in a bit of a mess. I have deliberately split the sound tracks off so that I can cut the picture mute and then shift theaudio track about to provide clean background sound (differing bits of chatter with a guitar plunking away).

During this it crossed my mind what I would do if I came across a useful bit of chatter that needed it's original picture? My first thought was to lay down the original clip again and edit in the relevent section (with a suitable cutaway shot to cover) but then I wondered if the sound track carried the timecode as well as the picture and if so, could I not match the time codes to regain sync. In other words it was something of an academic exercise.

My only excuse was that it was late, I was about to go to bed and I sent in the posting without much thought. A bit of a waste of the forum for which I apologises.

Do the files from which you extracted the audio now appear in the timeline with the little speaker showing Mute? (They should.) If so, simply un-mute them and you should still have the original audio attached to them. As I understand it, extracting the audio is a bit of sleight of hand. You get a separate copy, but the original is still hiding there...

Ah, that's what the little speaker is all about - you can tell that I am still on a learning curve - thanks, that will do fine and I will forget about trying to match time code numbers,(it's a left over from a previous existence).

Hi

If you wish to copy the audio you could Share Create Sound File, this will make a Wav of the project.
OR
When you Split Audio a copy of the audio is placed in the voice timeline

You can cut the audio timeline into sections using the scissors.

Use the library to save a copy of the sections, drag the audio sections to the timeline where required.

For background sound there is no problems with audio sync’
For lip sync’ you will have to be accurate.

Thanks for the tips Trevor, I like the idea of storing my audio tracks in the library. Memo: must suss out 'Library' properly. Got Georgie Hill's book yesterday, very interesting and well worth getting. It, together with Ulead's User Guide plus this forum, combine to offer first class help - better than I got with Pinnacle. Non linear editing is definitely where it is at - although there are still times, on quiet nights, when I miss those strips of images that made people laught and cry, not to mention the smell of film cement but that is going back much too far.

I shall have to do an article on this sometime in the future, just too many projects on the go at the moment.

There are some links here:

http://phpbb.ulead.com.tw/EN/viewtopic.php?t=2096

Firstly - if you wish to do a lot of Multi Camera work then MediaStudio is the way to go. MediaStudio enables you to cut and splice clips on the overlay tracks. This isn't possible with videoStudio - it's a pity - but then that is one of the reasons why you pay more for MediaStudio.

OK lets not get put off - lets see what we CAN do with VideoStudio.

Step 1. Create a new Video Library in the Library Manager to store your clips.

Step 2. Place one of the MINOR videos onto the video track, go through the video and select bits you wish to KEEP using the scissors tool. Each segment that you wish to KEEP - drag its thumbnail to the library above. Rename the Thumbnail for easy Identification.

Step 2. Clear the Video track.

Step 4. Place you MAIN video onto the video track. this video will form the anchor for the rest of the project. We will be using the soundtrack from this track only.

Step 5. Drag the thumbnails one at a time from the library onto an overlay track and position it where you wish it to appear. You do NOT have to be too concerned about audio/video synchronisation - unless it is a close up of someone speaking (Choose your clips carefully.)

Step 6. Mute the audio of the overlay clip(s)

The overall effect is that you have the main video playing complete with sound. You have cuts to another camera angle wherever you have selected them to occur. You keep the sound of the Main Video Track, therefore it should all appear quite natural and co-ordinated.

Hopefully when I get more time I will create a tutorial in a bit more depth.

Steve.
Thank you for your comprehensive offering on this subject, I like your suggestion and will try it out. The other links you suggested were also most interesting. Regarding sync: one useful feature of my material is the number of guests taking pictures and the resulting flashes which provide a visual clapper board to achieve pretty good sync between the three cameras.

One reason (among several) that made me switch from Pinnacle to Ulead is the image correction feature that VS10+ offers; all the actual wedding scenes and the folowing dinner/speeches were shoot under very poor light conditions and while I don't mind my speech to be lost in gloom, I have to try and improve the picture quatity generally. I found some useful stuff on this in the forum.
