I've made a circle animation I want to use to illustrate that a button on a smart phone has been pushed.
It's an animation of concentric circles interacting quickly then fading away, just about 1 second. I created it in Premiere,2018 essential graphics, but it has a black background, while the circle animation is red. I'd like to export it but I don't want the black background. How can I export it without the black background and with an alpha channel? I turned off the "composite" in the monitor view and chose "Alpha" there but my red circle turned white so that's no good. I'm thinking I may have to make the red circle in illustrator but I don't know that program, so I hope there's some other way. Thanks for any help!
Place the animation on the timeline. Clicking on the wrench at the lower right corner of the Program Monitor, set the monitor to display the transparency grid:If your animation looks correct (the transparency is correct) then export the animation from the timeline in a codec that supports a matte channel, like ProRes 4444, or QuickTime Animation.MtD
Meg, Thanks for your help. When I did as you directed and set Quicktime/animation codec, I still got a black background in the output. I went back and tried it again. This time I checked X render at maximum depth (and under that) X 8-bpc + alpha. That time it rendered out my circles with an alpha channel. Yea!
