“Yi M1 Micro Four Thirds camera” and “the camera that I am developing which also produces DNGs”
Your post sounds very much like a problem having to do with the unusual gear that you are using. I do not experience anything like what you describe with my FUJIFILM X-T5 and FUJIFILM X-T4 cameras.
Sounds more like a request for expanded support than a feature request that most other users of Nitro would benefit from.
