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.

[mattv51698573]

Yes it was already unchecked thanks.

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

[mattv51698573]

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

The only times I have had that happen is when there are some rogue keyframes on the opacity effect at the end of the clip - generated by me accidentally!

Hsve you checked each clip for bad keyframes in the effects panel ?

Curious why you are using both Opacity keyframes and dissolves? Does it fix issue if you only use one or the other?

[mattv51698573]

Yeah that sounded confusing. I meant that I tried them both, not at the
same time, to see if one or the other worked, but they both have the same
problem.

Right-click on the 0% keyframe and set it to "Ease In", see if it helps smoothen it out.

Usually, Dissolves with Opacity keyframes don't play nice, try to avoid it, speaking from experience, keyframes are so much better than dissolves if you can get what you want with only keyframes.

I figured it out! I was layering many clips and had all of them at 50% opacity. As long as the bottom clip was at 100%, I wouldn't get the weird flash at the end of the fade.
