During panning, only a thin strip on the left or right side of the screen actually contains new information. Of course, compression algorithm has to be smart and recognize that the remaining part of the image has to be shifted.Again, people are arguing about blur without thinking about compression impacts.120 fps with 1/120 s shutter speed is both sharper and smoother than 24 fps with 1/48 s shutter speed. No staccato occurs.I like the 24fps 1/48th look. And pretty much only that look.
120fps means 1/120th minimum shutter, which is too fast and "stacatto" ... not my style.
Spielberg shot "Raiders" on 24fps and it looks _amaaaaazing_ so if it's good enough for Steven Spielberg and George Lucas, it's good enough for me.
In most compressions these days, you have a full key frame that's updated with pixel changes. When an actor is moving in front of a fixed scene, only the actor's pixels need to be updated. If you pan, all pixels have to be updated. What happens then depends upon your bandwidth, which tends to be fixed fairly low on our cameras, and also on downstream service providers, as well.
This is why the ASC and other Hollywood organizations are very careful in their testing and comparisons. You have to eradicate all the "other stuff" to talk authoritatively about "one thing."
I'm pretty sure that it's not a compression issue. Have a look at this example that I already mentioned in one other post:
