I'm pretty new to this sort of editing, although I have a pretty good basic level of understanding of simple PrP editing and workflow. I have a UHD sequence that is quite long (about an hour, lecture material) and there is generally more field of view than necessary. Ideally, I'm looking to take about a 2880x1620 crop of what I have and follow the speaker, then output to 1080. I get how to track the speaker (at least I think I do), then I thought to apply the track motion to a new composition that is the appropriate size. However, it seems you can't anchor a composition window to the track motion data, so I'm guessing my idea for how to do this isn't the typical workflow?
I tried searching for something similar but all of the examples are for something different, so I must not even have the correct words for this process. Any help is obviously much appreciated!
