Warp Stabilizer EXTREMELY Slow

It's not really meant for long clips. And 4k Warp is very slow.

You've got 4k long-GOP media, and half your 36 minute timeline has Warp applied to it. And color.

Um ... that's a load. Seriously.

Warp is the heaviest resource demand of anything in Premiere, even exceeds Neat video noise reduction. And then you apply it to long-GOP which takes a ton more processing, and add color. Yowza. I'm not the Mac expert here, and I know some Macs to handle the long-GOP stuff pretty well. But that is a load.

I also noticed that it is full-range, which is simply wrong for anything but 4444 RGB files. Rec.709 8/10 bit should by the standard always be encoded in "legal" range. Which is what display devices expect. So you can run into issues with crushed blacks and such.

Without getting any benefit ... it's the exact same data, the same number of levels encoded to the file, just encoded differently. Marketing people for camera makers seem to think it's a cool option. But it screws over their users.
