Scaling 4K in 1080P Sequence

[Trevor.Dennis]

I'm a _very_ occasional user of Premiere Pro, to the extent I have to work out from scratch how to use it each time.  I have sync'd up a couple of 4K clips on a 1080P sequence, and Set to Frame Size.  So my question is have I lost the 4K resolution, Or can I open it up and reposition, and still have 1080 quality when rendered out?

I am also struggling to work out the difference between Scale and Set to frame size.

Thanks

With Set To, you're safe. It always works any resizing from the original pixels. Avoid the Scale To, though.

Thanks Neil.  I'm three minues in to a 60 minute video, and I can't swear to having used Set, so I'll replace those tracks to be safe — as you say.  I think I must be at that 'A little knowledge is a dangerous thing' stage.

You can also look at the Effects Control Panel, and check the SCALE for those clips, they should be at 50% if you used SET To frame size. There's also and option to control the default scaling. Like Neil said, avoid scale to frame size

That's really useful. I have been guessing when re-enlarging the 4K clips so far.  I don't even know if my workflow is appropriate.  I have the two 4K tracks above the 1080 master track, and uncheck Enable on the 4K tracks.  Then use the razer just before and after the points I want to use one of the 4K tracks and enable that clip.   This is a work it out as I ago approach, with a quick Google when I get stuck.

I was impressed enough to get excited about video again after watching the MAX sneaks this year.  I later thought that mabe the edit by text was a clever use of OCR, but it all looked very impressive at the time.

As Neil says, use "Set to Frame Size".

I also explain the differences in this tutorial:
