Hi Rohan
If I understand you correctly, you want to burn the SOURCE timecode on to your movie, not the SEQUENCE time code?
If that is the case, you need to drop a Video > Timecode Reader effect on to each one of your video clips on the time line. This will read the clip’s source timecode and display it as a burned in a superimposed box.
If you want the SEQUENCE timecode, you need to nest your whole sequence into a new sequence (so it becomes a single flattened clip on the timeline) then appy Timecode Generator effect to the whole sequence (you can set the start timecode).
Hope that helps
James
