If you double click on the picture above you will get a 2560 x 1440 enlargement. Note the info tab tells you about the original material (4K) not the timeline info. I decided to take the dance footage a further stage forward using the scale mode as a zoom, this allows you to contain the shot at the precise moments…this level of control is not available to you on one off live vision mix, in other words “off the hoof without a rehersal”.


Opening up Video Animation allows you to see your transformations… in this case I electronically zoom in to contain the shot and zoom out slightly still containing the shot. I also zoom in on a shot and perform a slow pan left to right. Also note with this type of electronic zooming you don’t suffer any “f” stop closure.




Only when you use the YAGH in a hurry do you discover why you don’t monitor any of the SDI outputs while in 4K…it only shows you a quarter of the picture !

Just to let you see some of the pitfalls I have edited a fresh dance with some jerky camera movement due to me using a photographic tripod and forgetting to lower the middle column which causes shaking when someone walks past the tripod.



Having been working in the video business since 1988 I have amassed a great amount of knowledge of both the kit and production values over the last 30 years.

  1. Excellent video information, as always – shame about the music in the production!

  2. Thanks for that. Zoom and pan from a single camera – wow! But I’m starting to realize than one has to plan well how to frame the original shot to be able to center the zoomed shot properly.
    I’m guessing you are using the 4k format that scales with 1080, not the slightly bigger one?
    Also, good point about the aperture.
