Rendering several timeframes

How do you join two timeframes in a project into one render so that they are both together. Or can you do that?

Moved to the Resolve forum as I’m assuming that’s the application you are referring too.

Are you referring to two different frame rates?
Just define your target FPS for the project and drop your clips into the timeline without letting DR change it.

Is there a separate forum for Resolve?

Yes, you are in that forum right now.

Create a new timeline. Other timelines can be treated as clips so you can drag and drop the other timelines in your new timeline, trim, etc.
