Hello,

 

I've tried this several different times, and I'm not sure what the issue is. I have an animation I made in Animate CC, which I exported as a .MOV file with transparent background. (I know that the file is working properly because I am able to use it with a transparent background in another program - OBS.)

 

When I import the .MOV file to After Effects CC, it changes the Alpha channel to solid black.

 

I have found countless articles about how to EXPORT a video with a transparent background, but none about how to IMPORT one. Hopeing someone here can help me.

Please & Thank You,

M

there are no special settings to import video file with alpha channel so if your file includes alpha channel they must come automatically with transparent background, so how did you know it's come with black background did you place any elements underneath your video and you still get a black background?

I think I know what you're asking. I'm going to answer in three parts:
- I know the background is transparent in the .MOV file because I can use the file in a livestream software and the background is transparent
- when I import the file into AE and put it over a white solid, I cannot see the solid. Where the alpha channel should be, it instead displays black in the viewport
- when I export it is the same

I have been having this issue since about 2 updates ago.

Your problem has nothing to do with the updates and everything to do with the render settings. What are they? Screenshots???
