flickering problem when adding new titles to old AVI files

[blacktooth]

A few years ago I made a video using VideoStudio 4.0. The video files were AVI files. This video project was never advanced any farther than this, as this was before DVD technology became accessible.

Now I have VideoStudio 8.0 and a DVD burner, and I decided to complete my old video project by encoding it to MPG2 and burning it to DVD.

However, I never liked the titles in VS 4.0, as they had no shadow feature. The titles just didn't show up very well. Since VS 8.0 has shadows, I decided to update the old AVI files - before I encoded and burned them - by adding shadowed titles on top of the old titles. It was tedious work, but I got it done.

I then rendered a new AVI file from the old AVI files and the new titles using VS 8.0. The newly rendered AVI file looks exactly like the old files, except that there is a slight flickering whenever the titles appear. The titles themselves don't flicker, but everything else on the screen does. It's too bad because the titles look much better with the shadows.

Can anyone offer any insight or advice on this flickering?

As some additional information, the original footage was recorded in analog 8mm. The 8mm tape was then digitized with a Digital8 camcorder and fed into the computer with a firewire as AVI files.

Thanks for any help.

Blacktooth,
No solutions, just more questions. Does the flashing occur if you put text anywhere or just where you overlaid it on the original text?
Do you have the source AVI without the original text?
Not that this will probably matter, but you said you re-rendered a new AVI from the old one. I thought you were going to MPEG-2?
You said the analog 8mm was digitized with a Digital8 camcorder.
Did you just record the video while it was playing on the screen from a 8mm projector?
I've been thinking about doing that with some of my families old 8mm.

Sorry for the confusion about 8mm. I meant 8mm videotape, the kind that was common for camcorders back in the '90s. I actually have some very old 8mm film movies myself, some of which I had converted to VHS several years ago. Anyway, the advantage of these Digital8 camcorders is that they'll play the 8mm analog videotapes, plus they'll digitize them as well. The disadvantage is that the camcorders are bigger and heavier than the other digital camcorder formats.

As for the other questions: I don't know if the flashing/flickering occurs if the new text is added elsewhere besides the old text. I'll give that a try. I don't have any source AVI without the original text. As for re-rendering a new AVI file, I would not have done that except that it was necessary (as far as I know) in order to add the new titles. Once a new AVI file is successfully rendered, I'll convert it to MPG2 with TMPGEnc.

Thanks again for any help.

Blacktooth,
Okay, my mistake about the 8mm. That's neat about the camera digitizing it for you. Didn't know they could do that.
In your reply you stated that you had to create another .avi file (from Video Studio I assume since that is where you are doing the new title work) so that you could render it to MPEG-2 with TMPGEnc.
Maybe I'm missing something again but why don't you just render to MPEG-2 from Video Studio?
Sorry, still another question that doesn't resolve your original inquery.
