Import of Canon MXF clip works but it is saturated green!

StatLaw wrote on 5/16/2019, 12:45 AM

Any help or pointers would be most appreciated!

I've received a directory of files with extensions MXF and CPF that appear to have been generated from a Canon recorder. When I import the MXF file into Vegas Pro 16.0 (Windows 10; build 424) it is highly saturated in green, so I'm guessing that there's something I have to do to alter the color space, but tinkering around hasn't gotten me any closer to figuring out what needs to be done.

There are two CPF files, a THM file and an XML file in the same directory. The files are as specified in http://www.premierepro.org/2016/10/canon-xf-c300-xf305-folder-structure-and-file-naming-explained/.

Here is part of a frame from the video, as it appears in Vegas Pro after import of the MXF file:

Hints? Pointers?

Thanks!

This is a non-standard Canon proprietary 12 bit RGB version of AVC which would need to be transcoded to a standardized video format before the use in Vegas Pro.

I suggest using happy otter scripts' Otter Bar import assist and the Magic YUV codec, as it edits well in Vegas and is visually lossless. You'll want to buy the $14 pro magic yuv 2.0 codec, as it supports the 12 bits this video is recorded in, and you'll want those 68.7 billion possible colors when coloring your video. After editing, be sure your project is set to 32 bit when you are color grading so you are taking full advantage of the added bit depth of your source material.

It definitely isn't the color space, it's recorded in standard ol' Rec709.

Looking a little closer, we have multiple codec IDs in the MediaInfo, Raw 444 12 bit and 709 YUV after C-Log or whatever is applied to output 2.2 Gamma.

Marco is saying, and I agree that the correct Canon color profile does not come with Vegas, but those who have luck rolling their own may want to give it a try.
