I tried retiming a clip in DaVinci Resolve to 200% and then rendered it out as an individual clip through the "Deliver" tab. However, the output clip is twice as long and looks like it has not been retimed. For example, the clip on my edit timeline is 30 frames long, but the output video has 60 frames.
I also tried using the "Change clip speed" setting as opposed to the "Retime Clip Speed". Neither made a difference.
Do I need to be doing something special when rendering out these clips?
