ARRIRAW Open Gate in Adobe Premiere

[July31932495ztr5]

We desperately need help...  A project im currently working on was shot in ARRIRAW 3.4K Open Gate on spherical lenses. The MXF/ARRIRAW Open Gate 3.4K has a resolution of 3424 x 2202.

The proxies for editing are in a resolution of 3424 x 2202 Apple ProRes 422.

What should the format of the sequence in Adobe Premiere be? When you like to see the full frame like the original shooted footage?

3424-by-2022 Apple ProRes 422 would be a Full Resolution transcode to a mezzanine format.  This would be good for editing if you're finishing in Premiere Pro and your workstation supports playing one or more streams of ProRes at this frame smoohtly.  Although, being that your originals are ARRIRAW, ProRes 422 HQ might be a better choice than ProRes 422.

For an effective proxy, you'd want Apple ProRes 422 Proxy at a lower, but proportional, frame size.

Thanks! 

What should the sequence setting in Adobe Premiere be, when you like to see in Adobe Premiere the full frame (like the original shooted footage of Arriraw open gate / maximum sensor area)?

Frame size in sequence setting: 3424 horizontal by 2202 vertical? Or 1920 by 1238? Or another format?

You would drop open gate clips into a Sequence set to your "debayer" frame size.  1920-by-1080 is fine.  

You would then reframe your source footage within that frame size as preferred, scaling each clip anywhere from 60% to 100%.  You could even push-in some, to about 105% to 110%.  If you decide to push-in more, replace the clip with an After Effects Composition and apply Effect > Distort > Detail-preserving Upscale.  This will allow for up to 200%.

Instead of a 1.78 aspect ratio (16:9), you could go with 1.85 or another film aspect ratio.

When the source footage frame size is larger than the Sequence frame size, I usually like to scale all of the source footage just small enough to fit in the Sequence frame size to start, repositioning the shots as the story starts to take shape - but eventually framing each shot such that it fills the Sequence frame size.
