Eddie supports proprietary formats like Blackmagic's BRAW and R3D/RED. The best way is to have those clips in your NLE and then use Eddie to pull in those clips.
If you're finding an issue importing a proprietary RAW codec, you may want to create proxies. This article describes best practices.
How to create proxies for Eddie AI:
Transcode your videos to h265 MOVs and use a low bitrate. Ensure the proxies keep the same start timecode, framerate, and resolution; you should even keep the same filename not withstanding the file extension. This way when you go from Eddie back to your video editing application, all your. media will relink and then you can replace your proxies for your original videos.
Why .MOV? Because MOV supports start timecode.
Now you can use Eddie with any unsupported footage via proxies.
