Is there planned support for embedded alphas channels?
Is there planned support for embedded alphas channels?
I find it strange that this hasn’t been developed. I mean, even if you just one 2-layer composite or effect, you currently need 3 streams of video/images. That’s a huge amount of bandwidth. Even if is was just supported in a single decent format (ProRes4444/DPX/Uncompressed 10b) I would adjust my workflow to work with it.
With smoke and fire vfx plates for example (which you would like to have the option of grading as separate elements), with 3 ‘video’ layers total), I currently need 5 layers in DaVinci and even though I’ve dropped down to ProRes to lower the bandwidth needs its still not realtime, probably because of all the processing required to playback 5 streams of 1080p!
I understand I might not realise how complicated this is to implement, but if anyone from Blackmagic is hearing please add this to the feature request list (-; (I’ll go see if one exists somewhere now…)
Just my 2 cents, I just needed to vent this somewhere!
Aside from that and some conform page annoyances (not being able to copy/paste sequences/clips into other sequences or bring in XML’s to a new video track), I really think DaVinci is an amazing piece of software and the development team should be commended on the feature improvements and additions!!
Best wishes,

I know its not really the same, but my workflow is to dis-embed the alpha channel, render it as a ProRes movie, and re-import it as matte, re-attaching it to its parent in the node tree. No need for multiiple layers.

You mean “Old Ben”? Ben Kenobi?

My terminology was out, by layers I guess I meant tracks (although not tracks visible in the conform/timeline so I can understand the confusion). I’m doing what you’re doing but thats still 3 streams of video for 2 layers and 5 for 3 layers, which must require more bandwidth and be more processing heavy than just processing a single alpha channel right? From my experience I need to create black and white RGB alpha mattes and add them as mattes, so that means its processing 3 channels when it only really needs to be one (an alpha! Lol).

I really would love to see at least one file format that supports its included alpha.
We just did a TV show and it had like 350 masks in one reel of 500 shots.
This is a certain way of killing Resolve and running into memory problems.
It is also very cumbersome to to it all manually , and even twice if the source footage has to be changed.
EXR and DPX play very well on Resolve, so it would be lovely if we could utilize their extra channels.A slice of color…
