The new MacBreak Studio episode is here and this time Steve Martin and Mark Spencer focus on the topic that is being talked about everywhere - 4K. There's no doubt that 4K is the biggest revolution in filmmaking in years and right now even phones support this resolution. And in the video below you will see Mark Spencer demonstrating how to use Final Cut Pro X's Ken Burns effect to create moves (camera zooms and pans) on 4K footage of an interview subject. Mark reminds that for obvious reasons when you are working with 4K clips in a 1080HD timeline, you have a lot of extra resolution to work with, so you get new opportunities and so, as 4K (3840 x 2160) gives you as much as 4 times the number of pixels, you can reframe your shots in post.
"But since it acts over the entire duration of a clip, how can you make a pan or zoom pause? With stills it's relatively easy since you can create a freeze frame between moves. But freezing a video frame would look rather obvious.
The trick is to first decide when you want your pans or zooms (or both) to occur, and cut the clip into segments based on those moves. Then use Ken Burns to create your first move just as you would on a still. When you play back, however, you'll see how after the move, the next clip snaps back to the original framing. Therefore, copy the clip with the move, then paste just the crop attributes (Shift-Command-V) to the next clip. Then go back into the Ken Burns effect and reverse it (top left corner, double-arrows icon). Now the starting framing on this clip will perfectly match the ending framing on the previous clip.
But the move reverses over this second clip. To keep the framing still, you need to line up the red ending framing box with the green starting framing box. It takes a little work to be exact, but especially for a handheld shot, you'll never notice a shift of a few pixels over the duration of the shot. You can zoom in to get more precise.
Finally, to do another move after this freeze, copy-paste this crop effect to the next clip, reverse it, and set a new ending framing."
