Video with opacity

Sun Mar 16, 2014 8:21 pm
Hello,

I want to have two layers of video and the video on top to have an opacity of 0.5. I scrolled through all the video effects, but none of them gives me an option to make the video semi-transparent (not using blue screen or masks).
Does anyone knows how to do this?

Hi,

You need to add a Transition to the top video, either Composite or Affine. Drag it to the length required or click on it.

In the Transition window you will see near the top on the left hand side a small triangle. Click the round 'back to beginning' button just below the triangle. Opacity can now be changed.

For loads more information :-

Affine is keyframable and can change the opacity over time.

Yes, but there is no option like "darken, lighten, screen, burn etcetera".

These are separate transition. Please take a close look.

But witht hose transitions, there is no fine-tuning of how strong the effect must be. The perfect transition is to be able to set the blend-mode AND the opacity, I think.
