    Hey team,

    I’m fairly new in Davinci and wanted to see if you guys could help me understand something come up with a. work around.

    So I’m just digging into fusion and have had an issue getting some of what I need.

    I’m half way through a pretty complex sky replacement, and suddenly realized that I wanted to try to Magic Mask out a subject that was moving against the sky.

    I dropped back to my original timeline. Clicked “Open in timeline” on my fusion clip to get to all of my media available to me. Took the clip into color. Magic masked out the subject, and had intentions of sending that clip, as a black and white mask, over to the render cue, exporting, and then bringing that back into fusion to serve as an alpha channel to key out my desired subject.

    After all of that though, it won’t me export that clip.

    —-

    Ive tried the normal fixes with compound clips and stuff but really don’t understand the DaVinci processing pipeline.

    I can export other clips on my main timeline no issue, but can’t get this one out.

    Additionally, is there any easier way to go after this?

    Like Davinci seems needlessly fickle about letting me get ahold of my own media at times.

    Is there any easier way to do this kinda rough roto-work inside of fusion?

    Thanks guys

    Like I’m genuinely baffled here.

    It seems like all the obvious workarounds are closed to me here.

    1. I try to take the whole fusion clip into color and use magic mask and it stops me.

    2. I try to copy and paste the clip I want into a new timeline, and for some reason the clip won’t come with me.

    I don’t understand why it seems like all the obvious workarounds are non-functional.

    Sorry for griping. 🙂

    How did you export that clip with the Magic Mask applied?

    If you create an alpha output in the node editor for that clip, you will be able to export it with an alpha. It works in the official version 17. You can then re-import the clip in the Media pool as a Matte.

    Regarding image-processing pipeline in Resolve, you may want to consult p. 1358 of the Ref. Manual which explains what is carry over from one Page to another, or not, in particular effects created in Fusion. You can pass your work directly from the Fusion page to the Color page using the Source Input in Color.
