Video with alpha transparency support?
Hi! I edit all the videos for my church, and I was wondering if there was support in Proclaim for videos with alpha channel information. My use case for this would be to create animated transitions between our live camera feed and our pre-recorded videos on the stream that I send to OBS - so I mean, mostly I'm just trying to be fancy - but this would also let people create pretty interesting custom transitions, etc.
I'm assuming adding support like this would be... non-trivial. And if it already exists, and I'm just missing it, yay!
If I don't let people know I'm wishing for the cool things, I can't expect them to just appear.
Wishing the best of cool presentations to all!

Hi Kevin,
Thanks for the feature request, we don't currently have a way to do so you're not currently missing anything. The best place for feature requests to be tracked for development is https://feedback.faithlife.com/boards/faithlife-proclaim. You can also see when we being to develop a request there.0 -
Thanks Sean!
I've added that request here:

in case other people search the forum for this.0 -
Kevin, are you using a Mac?
If so this, this is technically possible, as mov's support the pro res 4444 codec that supports transparency. And it also work out-of-the-box on Mac.
I downloaded a small 'fire' video with transparency and was able to add it to Proclaim and it just worked!
A couple caveats:
- The video needs to start totally transparent.
- It won't work on Windows,
As for why it needs to start blank, Proclaim currently uses the first frame as a 'buffer' while the video loads to try and make it smoother. So if your first frame is not transparent you will actually see it behind the video for the duration of the playback, as we layer the video on top of the first frame.

Dang that's cool to know, unfortunately I'm on Windows. Hopefully a way for this to work in Windows can be found! (Like maybe DNxHR support)

Bummer! I'll take a look at DNxHR and see what it would take to get working for Windows.

Just wondering whether there was any further development on this in terms of Windows support?
I was talking with someone earlier who is thinking of moving to Proclaim and apparently this is a requirement for them
Any updates appreciated
Thanks, Graham
