How to avoid clip overlap

[Mike Kujbida]

[Harry Putnam] “Do you mean I have to render this out twice? I see no other way to accomplish what you suggest.”

That’s correct. Video (MPEG) and audio (AC-3) are separate renders.
This allows maximum control over everything when doing renders.
AC-3 renders fairly quickly (usually not even enough time to go get a coffee!!) so I don’t even think about it.
You can use a “batch render” script to automate this procedure. There’s one built into Vegas Pro 8.

“And concerning the bit rate: What does it mean to figure the bitrate according to the total time of project?”

If your video is over 70 min. long (and you’re burning to a single layer DVD), you’ll need to use a bitrate calculator to maximize the video.
Here’s a link to the one I use.
Note that this links to a zipped file.
Vol. 1 Issue 7 of Edward Troxel’s free newsletters takes you through the DVD authoring process. I highly recommend reading it.

“192′ is that a default?”

Yes, it is.

“If it is a default, is there some reason for me to mess with it?”

The only reason people mess with it is if they want to either change the data rate (I personally leave it at the default) or alter the playback level (the AGC option in the “Dolby Digital AC-3 Studio” handles the level control issue for you).

“It doesn’t really matter that its in stereo of course but just curious how I would set mono?”

You have to go into the “Custom” options for AC-3 and select 1/0 C in the “Audio coding mode” box.

“And I guess it might affect render time and final size somewhat.”

I’ve never tried a mono render so I have no idea.

Thanks for the links.. looks like good stuff.

It might interest you to know that when I tried setting for mono with the ac3 dialog it rejects and says DVD requires stereo only.

When I tried to get out of the dialog box it caused a full on crash. After telling me there had been an exception vegas disappeared in the blink of an eye.

Far as time goes its a little heftier than you’ve suggested.
Its been running 8.5 minutes and has 4 more to go according to the dialog. So no its not a major concern considering the video part was well over 2 hrs. If I still smoked I could of had a coffee and a smoke.. hehe.

[Don Bloom] “HTHs”

Yes, and thanks for clearing it up some more.

Is there anyway to set the length of a picture or video clip to a certain time length (seconds). I am putting pic and videos to a beat and if if every clip I drag to the timeline is the same length it would really help me out. Thanks

Start off in the same tab I referred to in my first reply above (Editing).
About 1/3 of the way down the list of boxes is one called “New still image length (seconds)”.
Make sure it’s selected and then enter the desired time.
