prerender artifacts
Here I am again . . . knowing just enough to be dangerous. I’m doing a slide show with the basic Movie Studio. As a transition between slides, I’m using the push wipe. Because I added some quick moves and video brightness/contrast and black white effects to the stills, I prerender every so often so I can make sure my edits are to the music beats. BEFORE I prerender, my push wipe showed a small clean border that I had selected. AFTER prerendering, the border was gone and there’s some funky dissolve or scan line looking thing in my 5 frame transition. Help?!?!?!

Can you post before and after screen shots?

Mike . . . thanks for responding so quickly. When I opened up Vegas this morning, the artifacts were gone. So either my computer’s processing is to blame or my 2am eyes. I read another post about prerendering that using Dynamic RAM preview is a good way to go. I tried that and it works faster and I don’t see the shmush I had before. I’ll keep watching and post screen shots if I see it again . . . I would still like to find out what’s causing it. Thanks again.

Nevermind . . . my dynamic RAM preview only does about 7 seconds so I prerendered and got it again. Here is what I want and what I get (in that order).

Nathan, what format is the source footage and what are you pre-rendering to?
-
Mike – The source footage are JPEGs and I use the prerender tool. I hit “Shift-M” to selectively prerender a section of the track and the only format choice I have is a Windows AVI file. I haven’t dug into the Custom menu/Video to change the frame rate or the field order or the interleave.

Nathan, change your Preview window to Best/Full and see if that helps.

I tried Best/Full immediately after prerendering and it was worse. Then I tried Draft/Full and it was better. Maybe it’s just a function of my desktop’s power: I have a 3Ghz processor but only 1GB of RAM. I just want to make sure that when I render my complete project, it won’t look like that. I suppose I could render it and send it to DVD Architect Studio just to see what would happen. Do you think another GB or 3 would help?

Set it to Best/Full before you prerender and see if that makes any difference.
Remember too that a computer is a progressive display while a CRT TV is always interlaced.
Try burning a short segment to a DVD RW and see how it looks on your TV set.
My guess is that it’ll look just fine.
