Choppy video
I’m doing a simple experiment with masking. (mpg1 29.970 fps. progressive) Trying to have my daughter sitting at both ends of the couch, waving to herself, just 8 secs. long. Either clip plays smooth by itself but when the other one is added the video becomes very choppy/stuttery – both rendered and in the timeline. I’ve matched the proj. properties to the clips. I’ve been a Vegas (Pro8) user for a very long time but this one’s got me stumped. Pro8.
BTW – first post, longtime reader.

I haven’t seen anyone use MPEG-1 in a long time. Are you sure the footage is MPEG-1? I assume you recorded this footage yourself. What camera did you use? There should be no choppiness with MPEG-1 as this is a very old format that even the weakest of PC’s can process with ease.

Clip properties in Vegas reads it as mpg1. Imported from Sony DSC-P200.

OK that explains a lot. Video from a still image camera. A quick Google search reveals that this camera shoots something Sony calls “MPEG VX”. Not sure what that is but I’ll bet it’s at the root of your problem.
You can try setting your project properties to match the footage. Go into the properties (Alt+Enter) and use the Match Media Settings button (it’s the folder icon on the top right). This will make the project settings match the MPEG VX media settings. That might eliminate some of the choppiness.
If that doesn’t work, I would seriously consider buying a “video” camera for taking videos. Still image cameras are more trouble then they are worth when it comes to video.

John,
I appreciate your help. I do have other cameras and I guess that’ll have to be the answer for now. Strange because as I said the clips play fine by themselves. Thanks for pointing out the Match Media Settings feature. I wasn’t aware of it! In this case it didn’t help but is good to know. Time to get out the “real” camera!Bill

I agree with you that it’s odd that they play fine by themselves. So let’s look at how you are doing your split screen. Are you using Pan/Crop or some other method. Maybe the way you are doing it is causing Vegas to do more work than is needed?

I’m masking off one side of one clip. I was able to make a smooth-playing version by first re-rendering the original to mpg2. An extra step but doable.

That was going to be my text suggestion but I would NOT use MPEG-2. MPEG-2 is very lossy and then you are going to render it again to DVD MPEG-2 and loose even more quality. I would render to DV AVI which will hold up much better when editing and re-rendering.
