Yes, please.

So I frames often key frames, but...

is complete frames.

It's like an image, it's a JPEG, right?

You can start, you see everything, right?

And then the next image can be a P frame, which is a predicted frame.

So you take some part of the previous image saying, well, I need the block five and seven and 42,

and you replace it, and then you just give the extra information, right?

But that means that in order to decode this P frame, you need to have access to previous I frame, right?

And then, of course, you have more complex one, which are B frames, which are B predicted frames, which can depend on different type of frames, some in the past, some in the future.

And so ProRes is an intra-only codec.

For the people who can see, this is a very good one, right?

So I-frames are complete frames.

P-frame basically depends only on I-frame and B-frames can depend on in front.

You can even have, and we use that in terms on Kyber, is what we call intra-refresh, where

Basically, there is no iframes.

But so you never have an iframe.

This is intra-refresh that we use, right?

But for me, the biggest mind-blown when I started was the B-frames.

B-frames, means B-predicted frames, can depend on frames that are coming in the future.
