I have a Google Earth clip on the timeline zooming out to a point in space.
I put it on the time line and set speed to -100. So that it will zoom in instead.
When I play it in the timeline, it zooms in just as it should.

However, once it is rendered, it zooms out, instead of in when it is played. I'm obviously missing something simple.

Suggestions please.

Thanks,

Render as a Single Clip (not as Individual Clips) and it should work.

Tick the "reverse speed" instead of - 100.

Rendering as a single clip solved the problem, thanks.

Ticking reverse speed automatically sets speed at -100

Hi there,

Reopening this topic because I have a similar issue.

I need to reverse a clip also, except I want to export a cineform format where I get just the alpha, and I want to export as an alpha also.

The problem is that "export alpha" only appears if I render an individual clip, so the solution of exporting as single clip cannot apply here.

Is there a way to get round that?
How can I reverse an alpha?

Thanks.

If you change Cineform "type" to RGB 16-bit, the "Export Alpha" checkbox appears. Rendering reversed clips shouldn't change anything. If you're having trouble, try one that's not reversed. There's a lot of ways to mess up alpha export and import with Resolve. If you can't export it successfully, then you might not have wired up the alpha output on the color page. If you can't import it, then you might need to "add source" on the color page, and pipe the new green global input into a blue alpha node input. There are other ways to "import as alpha matte" when you only need the alpha, and I *think* you can even drag-and-drop, although I don't remember the specifics of that.

This changed in 17 beta 7.

I am still on version 16, you are correct.


Thanks!
