Green screen transparent layer questions video editing I have two (newbie) questions:

1)I have made a green screen video transparent in the compositing-tool. But when I am rendering this image (without a background image) and I am trying to place this in the normal video editing tool, it is not transparent. Did I do something wrong? Can I only render a green screen video with a background image? Or are there settings to do this?

2)I have downloaded a green screen video with smoke. But this smoke is too white, it would like to have the opacity 50% or something. Is that possible?

Thank you
Try exporting with ffmpeg, using RGBA(A for alpha), Container: Quicktime and Codec: PNG.
