There are shortcuts you can use to move the playhead frame by frame:
- Using the Mouse wheel on the Timecode counter.
- Using the small arrows next to the Timecode counter
- Using the left and right arrows on your keyboard.
I prefer the third option. When using the mouse wheel or counter arrows, the focus goes on the timecode counter (selected in blue). So to trim the clip, first you need to click elsewhere on the window to deselect the counter. Then you can use the “i” or “o” keys to trim the clip.
EDIT: Using the Tab key also works to remove the focus on the timecode counter.
You don’t have this problem with the left and right arrow keys.
