Text Overlay Problem

Galeng wrote on 11/19/2004, 10:57 AM

Hi,

Created a slide show with Imaginate and rendered it to AVI. The clip looks great, very crisp colors, very clear. Drop it on the Vegas timeline no problems.

Create text in the media generator to overlay on some parts of the clip. The text has alpha channel background and is placed on the upper level video track. Shows up where it is supposed to.

But, the problem is that wherever I have this text overlay the AVI goes slightly blurry. I can scrub before the overlay and after the overlay and the clip again appears very clear. Only gets slightly blurry when text is overlayed. I checked the alpha channel settings and the background is set to "0". Text is set to 235, 235, 235, 255 with a thin black outline of each letter.

I must being doing something wrong, but can't figure out what.

Any help is greatly appreciated.

Thanks,

Galen

Er . . is this in Preview? Try rendering a small piece and view on an external Monitor . . Pre-render will do . . Or even better, try a RAM render . .yeah a RAM render first . . try this!

Grazie

Hi Grazie,

Yep, did RAM render and also previewed on external monitor. Same result.
I wonder if it has something to do with Imaginate???

Perhaps you should check the properties of the AVI clip.

Also take a look at the same text laid over a Vegas rendered AVI

It will not have anything to do with Imaginate. Once it's rendered to an AVI file it shouldn't matter what created the file.
Adding to / changing any frame forces Vegas to render the frame for output so that's where things are going wrong. What qulaity setting are you using? Try Best rather than Good, might help.
Also what colors are involved? Shouldn't be an issue but worth a look into.
Is it just adding text that causes a problem?
Try say reducing the opacity to 99%, just that will force Vegas to render all frames. Work with small bits so you don't have to wait forever while you experiment.

I've had a similar problem with text overlays, for me, it's usually because the text layer is not at the same aspect ratio as the main layer or the text frame is not a multiple of 720x480.

Make sure that the text layer's aspect ratio is correct (rightclick match output aspect, in PAN/CROP) and/or if you resized the text layer with TRACK MOTION make sure that the text layer is a multiple of 720x480 (352x240, etc.).

This also usually fixes text interlacing problems too.

Good luck,
