How to avoid clip overlap

I'm trying to get a job done quickly by selecting my clips from the project media bins in the order I want them on the timeline then dragging them to the timeline in a group.
They appear on the timeline in the proper order but the clips overlap each other so much the dialog from one overrides or mixes with the dialog from another.
I don't want these clips to overlap and I don't want to have to monkey around with each clip. I want to dump them on the timeline and not have vegas `think' for me. There is no room for trimming.
How can I do this without having to carefully adjust each clip?
The overall goal is to place several (12 or so) clips on the time line in the order they are selected from media bin. Then move to each Begining/end of the clips and insert a marker for chapters.
Finally to render out in a format DVD architect will use without rerendering.
I think I understand how to do the last part, its just Vegas' `helpfull' overlapping that is causing to much delay.

you can use the SNAP tool-this will put the clips tail to head with no dissolve.
As for a format that DVDA will take without re-rendering just render to MPG2 and AC3(audio) in the first place from the Vegas timeline.
Figure the bitrate based on the total time of the project using AC3 audio render (name both the same except for the extensions-IE mymovie.MPG,mymovie.AC3, open DVDA, drag into project prepare burn done!

[Don Bloom]"you can use the SNAP tool-this will put the clips tail to head with no dissolve"
Don, Apparently I'm too dense to see how this works.
I've enabled the snap tool, then drag a group of *.mov files to timeline, the overlap still occurs just like before.
Looking thru the help file about snap stool, the confusing mass of information about the tool, and `snapping', I wasn't able to figure out how to use this tool to prevent overlap.

Well first do what Mike suggested then when using the snap tool the clips should snap head to tail - I don't understand why they would disolve or overlap when using the sanp tool unless you have the preferences set to do something else.
The clips should just pop right into place.

Not to over do the thickness of skull factor but when you say
"when using the snap tool" do you mean something more than simply enabling it?
About Mikes advice:
Sorry, I must have not had enough restarts or something in there because now, firing up on a new project I see it works head to tail, but enabling `snap tool' apparently has nothing to do with it since it works with it disabled too.

no, simply click on the sanp arrow on the tool bar and you should e all set. The reason I suggested Mike method is just to make sure. I honestly can't remember how my preferences are set and I'm not by my edit machine so I just wanted to make sure.
You should be good by simply clicking on the snapping arrow and then bring in the clips

I guess I'm being your worst nightmare or pest...
Do you mean I have to render this out twice? I see no other way to accomplish what you suggest.
And concerning the bit rate: What does it mean to figure the bitrate according to the total time of project?
In the save dialog, after choosing AC3 and then `custom'
A number appears in the bit rate selection dialog `192' is that a default? or something left over from previous settings?
If it is a default, is there some reason for me to mess with it?
There is no reason for this kind of audio to be in stereo or at 48 khz. I see how to lower the sample rate but it appears there is no way to control stereo or mono.
It doesn't really matter that its in stereo of course but just curious how I would set mono? And I guess it might affect render time and final size somewhat.

for the AC3 you can use the setting of 192 the bitrate pertains to the video side and it is determined by the time length of the project. For example a 60 minute project using AC3 audio (DVDArch preferred type of audio and it is also a smaller file) using a variable bitrate would be set at 8,000,000-8,000,000 and for the low end I alsways set mine to 2,000,000.
For a 120minute project using AC3 audio the bitrates would be (high)8,000,000 - (average) 4,826,000 and (low) 2,000,000.
If you use the proper bitrate the video will be fine. As for rendering 2 times well you are but you're not. You are rendering twice but once for the AC3 audio and once for the video at the correct bitrate. AC3 renders very very quickly so it's not a gruesome job.
HTHs

[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."

[Mike Kujbida]"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.

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
Re: How to avoid clip overlap by Mike Kujbida on Sep 13, 2008 at 1:41:57 am
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.
