Quality of video in DVD-A menus
Hi… sorry if this is a real “noob” question, but it’s got me perplexed. I’ve rendered out a video that I want to use as a “motion menu” in DVD-A. I created two images in Photoshop, dropped them repeatedly into the Vegas timeline (pic1/pic2/pic1/pic2, etc), then rendered it as a DVD-A MPG2 file at the best quality. In DVD-A, I selected that MPG file to use as my menu background.
Upon viewing the DVD, the main menu looks horrible, like it is interlaced heavily. This has happened to me before, when using already-rendered MPG files as part of a menu in DVD-A.
Can someone please tell me how I can avoid this? Should I render the image sequence in Vegas as an AVI file and use THAT as my motion background? Is the problem that I’m using rendered MPG footage, and then DVD-A is rendering it AGAIN?
Help! (please?)
Thanks!

Hello, My name is Craig. I am currently creating a website that I hope will be used by Vegas Video Film Makers.

Come and check it out. It’s still very bare, but the forum is up and going and also I have created a page about the “Preset Manager”
Thanks

I think you should render your menus to DV-AVI instead. As soon as you add any buttons/titles/anything else to your menu, it will have to be re-rendered to contain those objects. Therefore your MPEG2 menu is now being re-rendered to a new MPEG2 menu containing the extra objects.

Thanks once again, Ed. I went a step further and rendered as “uncompressed” AVI and it looked MUCH better, almost crystal clear. Would I have had the same result had I rendered to the much smaller DV-AVI? I wish I could go back to my last project and fix the menu, but it’s already in the customer’s hands! Ah well…
Thanks,

I would have to give that an “it depends”. Exactly what all was part of the AVI file? Were titles part of the file or where they added in DVDA, for example? The title would probably benefit from uncompressed. The standard video probably would not (especially if it was a DV-AVI source).

The AVI file was created from two images repeated, each one slightly different so that it created movement. Other than alternating lights, the two images were exactly the same and contained the text for the DVD title. The only thing I dropped onto the menu in DVDA were couple of image buttons.
Sounds like maybe I could have gotten away with DV-AVI, but since it was only a 60-second clip, the added quality of uncompressed may have helped out with the text, without creating too huge a file…?
Thanks for your help!
