Alpha rendering for cinematics

[zeOrb]

I've just started to play around with sequencer export in 4.13.1 and noticed it didn't render out an alpha which lead me to this thread. i wondered if i have to activate rendering the alpha somewhere or is the feature still missing?

Hey!

It's there, you have to change Capture settings to Custom Render passess, then you will see all the options in Composition Graph Options

And the Alpha render pass is?

Old thread but I came across this as well.. I think it's the opacity pass?

The problem for me is the motion blur does not compute with the other passes so anything but the finalImage output is close to useless. Might be something else I'm doing wrong but only the main pass works with motion blur..

It's strange that there is no real Information about the Alpha Channel somewhere on Google. I found this as a solution

Yes Compositor is the way to go as shown on that video. It works
