Davinci Resolve - Framerate Playback Conversion (60fps to 23.98fps) (Slow Motion)

In Media Pool, the Cut Page, or the Edit Page, right click on the bin and select "Clip Attributes..."

It's best to convert a clip before it's added to or edited in a timeline

From the "Video" tab, click on the frame rate pulldown menu and select your desired frame rate (23.98fps)

Press "OK" and now your clip will playback at the new frame rate
