There were some posts on EXR and ACES back before Magix bought and converted the forum. Do some searching for ACES.

EXR is just another image file format that is normally uncompressed, but later versions now have compression ability. The compression addition significantly reduces the file/directory size, but Vegas does not support those features yet. The format also has multiple layers like a photoshop file, which makes it good for compositing and VFX workflows. I do not think Vegas supports the multi-layered function and just reads the files as flat.

EXR is an uncompressed image sequence, where the image info is represented in Floating Point rather than 0-255 integer. It is designed to hold all the picture info from Film scan or High end Cinema cameras like RED or ARRI. Those cameras have higher latitude and color depth, therefore need a more robust way of storing that info without clipping. EXR 32-bit supposedly has the capacity to contain the entire ACES color space with room to spare.

Since the material is Floating Point, most systems will not be able to "turn the math" in order to playback smoothly in 32-bit Full Project modes. Vegas also has problems with monitor View Transform accuracy, or at least it would seem.

To use EXR, you create a directory of your footage, then import the footage as an image sequence for editing on the timeline.

 

I want to do this on VEGAS Pro 18, but the option is blocked (as seen in the image below)

And when I import a single frame from the sequence, it doesn't go to the timeline, furthermore, none of the frames are recognized in the Explorer.

What settings should I put on the EXR images? What Codec, Color Depth, etc?

Did somebody say:

@Alex_EL I just created a bunch of EXR using Vegas Pro 21 & Boris's Silhouette, I can't get [lacuna]

here?
