I recently uploaded some 4K animated graphics that have an alpha channel. The footage is compressed Prores 4444.

I noticed that the Adobe Stock site is staying that the 4K version is Prores, but that the the auto generated HD version of my 4K footage is compress as H264, which doesnt support an Alpha Channel. So if someone buys the HD version of my footage, they are not going to get the Alpha.

Is this a bug?

What are other people doing as far as uploading footage with Alphas?

Thanks.

Footage+matte. The clips will be twice as long, but "alphable" when downloaded in any resolution. You can't do anything about the way stock resize and recompress your content.

I've used that method in the past. Haven't uploaded animations in a few years and was hoping that footage with alphas would be full supported by now.

Hi Forrest,

It's something that we've discussed internally a number of times.  Briefly, here's what I see as current issues: a codec that is modestly sized and supports alpha channel, a filter to include alpha channel in searches (currently not on Adobe Stock), method for previewing a file with an alpha channel.  Each of these could be expanded upon but I would be digressing. ;-)

We will definitely add something in the future and I appreciate your input and feedback. For the time being, I agree with the former reply.

Thanks,
Dennis
