Typing in specific timecode and going to that point on your timeline is less intuitive in DaVinci Resolve than Premiere.
If you’re in the EDIT page, and you go to the top menu PLAYBACK, select GO TO, and then TIMECODE, the timecode above the top right of your playback viewer will become active and you can now type in (or paste) manual timecode information. Once you hit ENTER, the playhead will automatically jump to that spot on the timeline.
I have PLAYBACK, GO TO, TIMECODE mapped to “T.” So I can simply hit “T” and then type in new timecode.
This timecode above the playback viewer is editable, copyable, and pastable. The timecode above the top left of the edit timeline, however, is not.
