I've imported a long MOV file (50 mins, x264) and I want to do some speed control over it.
I deleted the audio track to focus just on the video track.
I have dope sheet and graph editor open too.
In the Sequencer View, I right-click on the track and left-click to a specific frame. I press I and nothing appears in the dope sheet, the timeline or the graph editor at all.
So, I create a strip (speed) and right-click on it and - as shown in the official docs - untick Stretch Input where I expect the Speed Factor box to show the current frame.
It does not. I press I, nothing happens.
