Visual Proxy not working for DNG?

[Carlo Didier]

I recently got a drone which shoots jpeg and raw. The raw files are in DNG format.
As I edit those with CaptureOne, I generate visual proxies, same as for other raw formats (RAF, NEF, ...). They display correctly for all configured formats, except the DNGs.

Attached my setting with test and what is displayed. The JPGs in the second row are the proxies and the DNGs in the first row should look exactly the same.

Did you enable the version/proxy option on the "Versions" tab in that dialog?

Yes. And as I said, it works for the other formats.

Your rule looks strange, with the extra (). Is the JPEG shown as a version of the DNG in the version panel?
Other rule also matching these files?
IMatch does not contain any special rule for specific file formats. It always applies the rules as they are, from top to bottom.
The last matching rule wins.

You gave me the right hint. Cleaned up my versioning/buddy/proxy definitions.
Turned out I had used a "*" (zero or more matches) in one formula where it should have been a "+" (one or more matches).

What do you mean by "extra ()"?

By bad. Was working mobile and could only see your screen shots in small.
