Hi,
I've been using After Effects to edit some green screen footage, I now want to export my files with a transparent background so I can use in Premiere. However I must be doing something wrong as it just exports with a black background rather than transparent, I've followed tutorials (exported as rgb+alpha) but it just isn't working. What's odd is it worked a few days ago. Screenshot attached can anyone advise please?
Thank you so much!
Also all tutorials say to export as Quicktime... is that correct? Which other video file formats can retain transparency?

Quicktime seems pretty much broken. Use another format like the native ProRes or DNxHD exports or an image sequence.

Does it appear with a black background within Premiere Pro, or when you export it do you reproduce it from the Finder? It might seem logical but remember that you should import it into Premiere Pro and verify whether or not it has the alpha, not from the Finder. If that does not help, try QuickTime but with the Apple ProRes 4444 codec, this supports alpha.
If you put it in the Premiere Pro Timeline over a video that should be seen in the background and you still see it black then you don't have the alpha. This would be the easy way to check if you have the alpha. What you're doing is a better option, insert the After Effects composition directly into the Timeline, so you don't even use additional space on your storage disk.

Thank you so much although I'm still strugging...i can't seem to export video and audio together with a transparent background 😞 My computer takes so long to export and then I discover it hasn't worked....

This is really helpful advice thank you so much. I've been getting around it by importing my sequence from AE directly into Premiere.... I'll try the settings above but when you say I have to 'verify whether or not it has the alpha' can you tell me how I do that please? The black appears when I place on my timeline in Premiere...

Ah thank you yes that's the way I check if alpha has retained. One additional question when I do import my AE composition into Premiere and I make the slightest change the render line for that vclip turns red. I then have to go to Sequence, render clip which takes ages... what am I doing wrong? I've never had this problem before? Thank you so much for your help by the way!
