Proxy frame size for mixed footage - 4k (4096 x 2160) + UHD (3840 x 2160)?

Hi all,

I have a few related questions. I'm on a Mac.

1) I'm shooting on 4k (4096 x 2160) + UHD (3840 x 2160) + HD (1920 x1080) + have old archival 4:3. I plan to make proxies for at least the 4k & UHD files, in Quicktime. They will all go in the same timeline (see below).

If they are in a 16:9 timeline for example, how can I make the 4k proxy so that it fits properly without the black lines on top and bottom? I did a test and it seems like the 1280x720 is good, but it still has the black lines at top and bottom.

2) What are the best sequence settings 4k + UHD + 1080 footage in one timeline? I may export as 4k, or may export as HD (and if I do HD, I may zoom in on some of the 4k/UHD so as to have a wide and tight shot). Do you recommend I set my sequence as 4k, UHD, or 1080 (especially if I may zoom in a lot on some of the shots)?

3) If I plan to zoom in to my 4k footage in a 1080 sequence, but am using proxies created at 1280x720, do I set the scale of the shot in the proxy or the original footage, and what will happen when I export 4k original at 1080 (to make sure the increased scale of the shot holds and is taken from the original footage)?

4) How can I tell whether a clip is a proxy or an original in the timeline?

Thanks,

Karin

I'm in the exact same situation you describe. How did you eventually workflow it? How did it work out for you? Anything special to watch out for?

1. You'll need to create the proxies in two batches. 1280 x 720 for the UHD and 1024 x 540 for the C4K.

2. Edit and export at the lowest resolution media. (1080 in your case.)

3. Premiere Pro is very smart about proxies. You won't have any troubles here. Just edit normally.

4. There's a Toggle Proxies button you can add under the Program Monitor. If it's blue, you're using the proxies.

HD timeline, keep source at original size for proxies to better judge zoom?

’Set to frame size’ for 4K (*not* scale to)

You could use BITC for proxies - can be subtle - with embedded clip name & timecode you’d be able to track back. Needs to be fairly central to still be there post zoom though!
