dissolves and opacity changes work in Premiere but show a slight change in brightness in exports

[mattv51698573]

I am editing large PNG's in the current version of Premiere Pro. I am layering them and using both opacity changes to 0% and fade outs on the layered clips. It looks fine in Premiere, but the exports, whether they are h.264 or quicktime, show a little blip of brightness as though at the very end of the fade, it doesn't go all the way to 0% opacity. I have tried everything but nothing works. Has anyone had this problem or know how to solve it?

Thanks!

Have you tried unchecking composite in linear color? Sometimes that fixes such things.

Yes it was already unchecked thanks.

Also check your renderer in Media Encoder(if exporting there), is it set to software only?

Do you mean the encoding settings? It is set to hardware. I don't see a renderer option.
