Smooth Playback issues
Originally posted on the Vegas Basics Forum;
We’ve been using Vegas since version 5 here at our studios for audio and audio post to video. We’ve always had the same issue. Playback of video is almost always jumpy. We are using Vegas Pro 8.0b on all of the machines and they are fairly up to date. The machine in my stdio is a Rain Recording Labs Element witha core2duo 2.13 and 4 gig of RAM. It has an Nvidia GeForce 7900GS video card and I’m outputting to the monitor with a Blackmagic SP card. I’ve also tried output through a Canopus box with the same results. Our clients will usually send us a Quicktime to work with and usually it’s fairly low res. I know that’s part of the problem. I had also had this issue with completely uncompressed video but not nearly as bad. Would a stronger video card help. (512mb or larger) Is there anything else I can do. It’s embarrasing trying to play these things back with clients in the room sometimes. When I’m using Nuendo on my movie projects with the same hardware I don’t get these issues. And yes I get the same crappy quicktimes from the movie studios usually.
Thanks for any help you can provide.

Vegas does not use your graphics card for playback so buying a new one won’t help. Vegas uses pure CPU power and a 2.13Ghz is at the low end of the scale. If these files are highly compressed that could contribute to the problem.
Your two options are to get a more powerful computer or render the video to a format that Vegas can preview faster. If these are SD quality files, rendering them to DV AVI would be the fastest format for playback.
If the customer brings the file with them and expects to see it immediately (i.e., there is no time to transcode) then your only option is to get a more powerful PC. 🙁

Could you give me more specifics on the DV AVI format. Which settings would work best?

Select AVI as the format and use the NTSC DV or PAL DV template depending on what country you are in.
