Alpha Channel changed to Black when Importing Video File

[Huelick]

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???

[Huelick]

Here are the prefered render settings. I have also tried exporting it as a PNG sequence with alpha channel, to no avail.

As someone who face the same problem in 2023, and did not fix. Adobe team, did not have improvement for this issue. Weird!

I somehow fixed with re-loading in project window... Stupid but worked for me...

I've been having the same problem since the last update. I've only found one primitive but working solution. import the animation/video into Photoshop, make sure the background is transparent, and then export it with alpha channel from Photoshop.

Why not just import the fla file into AE?

Столкнулся с тем же самым, сделал экспорт RGB + alpha channel через Adobe Media Encoder и черный бэкграунд пропал

Is it because your alpha is ignored? RIght click on the .MOV file, look for Interpret Footage > Main. On Alpha section,  change the setting to "Straight" or "Premultiplied", instead of "Ignore".  It works on me. 

I hope it works for anyone that encounter this problem.

[Lim27238822tfbh]

Oh yeah, if it doesn't work, right click and pick Reload Footage. It should work.
