4k rocks for pan and crop

So I bough a Panasonic LX100 to dabble into 4k (and get a nice travel camera). I record my daughters' dance and theater performances, figure I can pan and crop in post production without needing to carefully follow the performers as they move across the stage. Let me tell you that the resulting quality, and ease, exceed my expectations.

I recorded the same performance in a well lit arena with my LX100 and a Sony HDR-PJ540 camcorder. With the camcorder, I carefully followed the performers and panned and zoomed. It is stressful, you aren't enjoying watching the performance on a small screen. For the LX100 I positioned it on a tripod, zoomed to capture the entire stage, chose the manual settings and pressed record at the right time. In post production, I set my pan and crop points in about 10 minutes. At times I cropped up to about 2300 pixels wide (so threw away 2/3 of the image recorded).

The results? Everything is of course as smooth as can be. In the resulting video, the view magically knows exactly where the performer's feet are going to be seconds in advance and gradually moves to always just include them. Plus, even after throwing away so much picture, the color and detail is phenomenal compared to the HDR-PJ540 or my Canon 70D. I am a convert, I'll never go back.

what software did you use for it?

I've only extracted key frames from my 4K video (RX100 IV) via ffmpeg....

was at a marathon trying to find a friend who's running... left 4K camera recording while trying to find her... I only saw her side/back, but my camera captured her running past me, and could extract key frames and get decent 8mpix pictures..

I use Sony Movie Studio HD Platinum 11. It is definitely slower working with 4k footage than HD. My machine is a i5-3570 with 8 gigs ram. I turn down the preview quality all the way. However for rendering and the ultimate result it doesn't matter.

Note that I'm very familiar with the software for regular HD video, and have used the pan/crop tool for static picture hundreds of times. But it really is quite simple, scroll through the timeline to the extremes of where the performers move, and position a new crop at that point. To make sure it is smooth, I don't do it too much - I think about every 10-20 seconds or so there was a new crop or pan point.
