One of the things people ask about shooting with the RED ONE is, “Why do you need all that resolution, especially if you’re going to finish at HD resolution!?”

Here’s one reason, and it’s the same reason you might shoot with a still camera that creates 24-Megapixel images, every now and then, you may want to crop something.

For documentary style interviews, you usually have a few choices on how you shoot. You can use two (or more) cameras at different angles and/or with different crops. For instance, one camera might be tight on the person’s face, while the other shows their whole upper-body.

With multiple cameras you will need to deal with at least twice as much footage, and deal with syncing as well. Here’s another idea…

First, here’s our visual to compare the size of HD footage to 4k footage from the RED ONE:

Size Comparison

The full size of the graphic represents a frame of 4k footage from the RED, while the smaller rectangle in the upper-left corner represents the size of 1080p HD video.

So let’s suppose we frame our shot like this:

4k Footage

We’ve got the classic sitting person, with the upper half of their body in frame.

You could size this 4k footage down to HD resolution and be done, but with all the extra resolution, we can crop in on it and create what may appear to be additional cameras.

RED to HD Sample 1

Same camera, same footage, tighter crop… And we can even go further:

RED to HD Sample 2

A tighter shot is often used in an interview situation when you want to emphasize what the person is saying. Using this trick is one more way to get some use out of that extra resolution you might have otherwise not used.
