If you look at the vegas spec sheet, you would see that vegas has a 4096x4096 limit. Your footage is 5120x2700. I would suggest using REDCINE-X and reduce your image size using the crop feature or reduce the camera record size to 4K (4096x2160) if you want to use Vegas's native R3D support.

I wrote this for Sony RAW viewer, but you could experiment with this route too, just change the settings in cine-x to roughly match. This process would handle your footage in ACES color space, but do some serious tests before settling on a workflow.

"Here is the workflow I used on the clip you uploaded.

CineX Export

Export format OpenEXR

Video No Compression or ZIP or PIX, Use ACES

ADD Checked? - not sure about this one.

Export to folder


Vegas:
Import EXR image sequence, then change the clip media color space to ACES

Change project settings to match clip format, and color space to 32-bit full, View transform to ACES RRT (sRGB)

In the project media, right click the EXR sequence and select Create Proxy.

From here you can drag the clip to the timeline and use 32-bit effects only. Unless you have a super high end display system out of your computer, you will be looking at a transform to the sRGB color space. Digital Cinema will have more range.

You should be able to edit the footage and play it back in Best/Good quarter setting at full frame rate. If not, then you can switch to Preview Auto to make edits at full frame rate via the proxy file, then switch back to best to see the details and colors.

To render out create a new render profile that is the size you want ,for example 1080p@25fps, and under the project tab choose color space ACES RRT 709. I used Sony AVC and not MC mp4.

This way your edited project will retain the info the camera is capable of capturing, and you can output to any format that is required, including DCP with the right codec loaded.
