I want to get a stationary view on a moving subject, which needs to be staying within his square box on the final video (the camera should follow him).
So far I got away by clicking every 15 second to create a new keyframe and drag the canvas such that the object is centred in the final 1×1 layout.
I am going to automate this with a simple Python script.
The output of the script could be a sequence of coordinates, in whatever format Premiere wants them, so that it would replace my desperate clicking (45 hours of footage overall × 4 × 3600 = 650k clicks). Hence, does anyone know how to import / export keyframes so that I can figure how to craft such a hack?
Alternatively, but I don't fancy this, I can crop the video using ffmpeg and import that, but that wouldn't allow for later corrections.
