Render Quality
I’m on a PC with After Effects Pro 7.0
I have a large (5000 x 5000) mosaic in After Effects and it zooms in and out on various parts. I searched the forums and after experimenting with several different rendering and export options I found that a JPEG sequence looked by far the best. Now after 60 hours of rendering I finally have what I thought would be the perfect file to put into Premiere Pro. However, I had forgotten that there is a part of the file that has a transparent area that shows up as orange in the JPEG file.
Is there a way to render as a JPEG sequence if there is a transparent area in the file?
Thanks to everyone in the forum. You are life savers.

I suppose you could render a custom alpha channel (used as a luminance matte in your compositing/nle app.
Try this:
1. precompose your final comp.
2. apply => effect => generate => fill. fill new precomp with white.
3. create a black solid (comp size). place this layer underneath the first.
4. render this file for use in your nle.
5. apply this new file as a luma matte/key to your jpeg sequence.This is of course assuming that you want this area of transparency. Considering this is probably going to be a lengthy render you should probably wait to try this until someone else verifies that this is your best option. There are probably plenty other options out there. Hope this helps.

have you tried a quicktime with the animation setting? This always works for me. looks great and supports straight and premultiplied alphas.ian

I have tried Quicktime with animation settings but when the camera moves there is a lot more blurring than there is with the JPEG sequence.
I’m not sure why.
