Is there a node that shifts a clip in time.
I begun using more and more that I mix 2 or more clips in the timeline and blend them together, but soemtimes I need them to start at different frames.

Edit. I found it in the External Matte menu. The Offset slider

in Fusion/ReFusion ?

The Timespeed and Timestretcher nodes lets you index time at an arbitrary point.

Hiya sorry. This was for Davinci. I have found them in Fusion.
I guess I may be pushing the boundaries of what can be done in the Davinci Color panel, but I really like to stay withing it as long as possible since the playback speed is so fast.

On another note. How would I convert an RGB image to a matte/alpha? I would like to take the luminance from a color image and "convert" it into an "alpha"/matte so that I can mix it with my other mattes I have.

Why not just move the clip in the Edit page?

Hm, dont think that would work here. I have 2 or more clips inside the node tree in colors and I want to offset one of them in time. It seems to work if I use the matte offset settings. (I mean it is not really a mate, but the node is called "matte")

You can pipe a desaturated color output from one node to the mask input of another node and you effectively get an alpha channel.

What I prefer to do when mixing alphas is the reverse: pipe the alphas into color inputs and then use layer mixers / normal color tools to manipulate them before piping the result back into a mask input / clip alpha out.

That is a great idea. I will do that instead. Thanks!
