White Bar over half my renders

[Arie Stavchansky]

I’m not totally sure, but it looks like it might be an artifact that was left from your keying process. You may want to play around with the parameters for adjusting the screen matte view of your keyer. Were you using keylight that shipped with AE? You may just need to clean up the noise left by the key.

Is that edge part of the blue streak layer that appears over the man? If so, mask off the layer with a feathered edge so the white is not such a harsh edge. Or try a different blending mode to get the white out.

No its not…the reason it is only on there when we have shots rendered from after effects. We have many other shots in our video that are done in after effects scenes with a white room but when elements pass from left to right you see the white bar. Is there any other reason for this…if more screen shots are needed ito figure out the problem. I can deliver

[Kyle Brodeur]

I see where you are going but we use keylight on only one scene… everyone of our ae scenes have this annoying white bar and we don’t know why. The screenshot above is made using a plate behind it and the man being wiped up with a cc particle layer over it

This is only happening when you view the rendered quicktime in movieplayer ?
Not when you’re viewing the comp at best quality in After Effects ?

If only in the final QT, try rendering with a different codec or exporting a still.

[Kyle Brodeur]

Yes, Exactly…

When we render stills it looks fine. When we render quicktime in Premier Pro or any other adobe software other than After Effects it looks great.

Quicktime has been the best quality setting we’ve used so far.

AVIs have been very bad looking with all the grain and lines.

Do you happen to know why the quicktime setting is doing this?

is there any other render setting you could suggest that would give us the quality equal to quicktime?

I have found issues also with rendering out quicktime files in after effects. My avid does not like bringing in quicktime that have been rendered in after effects so i render out PNG of TARGA sequences for all my projects.

[Kyle Brodeur]

premier has no problem bringing them in its just for some reason after effects is leaving a huge artifact over my comps when i render quicktime…. if i use a tarfa sequence wouldnt that have a really big file size? i would like to use something equivilent to quicktime but be one file not many

[Kyle Brodeur]

we use a sony hdr fx1 on the dv setting and import through realtime capturing with premiere pro cs3. it comes in to the computer as avi… not only does this white bar problem happen when we composite with film, it happens when we make things from scratch in after effects we have several scenes that do not have any film from a camera just elements brought into ae and manipulated and the white bar still happens

Are you on a PC ?
I’m suspecting this is a Quicktime problem,
try any other codec and check if the problem persists.

By using another codec, I don’t mean switching to AVI,
but choose a different output codec in the “Format Options”
