Transcoding to Proxy with different frame size

Hey All,

hope someone can help,

I have footage in REDCODE 2K HD and 4k HD and did a transcode to Proxy after importing by selecting all the clibs in my timeline. The 2K HD clips were transcoded into with the same frame size (1920 X 1080) but some of the 4K HD was transoded into either 4K proxy or 1920 X 1080. My project is set to 1920 X 1080. I have no idea how it happened but I'm trying all the poxy media to be transcoded into 2K HD (1920 X 1080). i deleted some proxy files, tried to reencode but same result...gave me 4K HD again. What controls this? Why were some 4K clips converted to 2K Proxy and others were not?

Any idea here?

Best

2K isn't 1920x1080. 2K is 2048 horizontal. Don't know about the 4K proxy files, but usually 4K and 2K proxies are 1920x1080.

None of this is RED RAW?

Tom,

You are correct, 2K is 2048 Horizontal. But 2K HD is 1920 X 1080. It's a new setting that RED implemented into their cameras with the latest update because it is more conform with 16:9 aspect ratio.

You can read about all formats in the RED Epic/Scarlet manuals.

All of it is RAW...the camera shoots in raw that's why I want to transcode to Proxy. I'm just curious why some 4K HD RED RAW files are tarnscoded to 4K proxies, some are transcoded to 1920 X 1080. There is no option as far as I can tell to change that setting.

Never heard of 2K HD. Sure it's 1920x1080? That's just regular HD. Why would they call it 2K HD?

The 4K proxies I have are 2048.

Unfortunately all I could find in the Epic Operation Guide is this, which doesn't give the frame sizes for each format, just what RED calls them.

If 2K HD is 1920x1080, what's 1K HD? 1280x720 I guess.
