I've completed Beta 5 of ImageIngesterPro (Mac only).
Once you've saved one or more Camera Raw settings in Adobe Camera Raw, you can choose the settings you want from a new menu on ImageIngesterPro's main window. If you've also chosen a metadata template, the Camera Raw settings will be placed inside the resulting XMP sidecar by ImageIngesterPro. If you're converting to DNG also, DNG Converter will incorporate the Camera Raw settings, along with the rest of the template's metadata, into the DNG. What's more, DNG Converter will use the Camera Raw settings when creating its JPEG Preview. If you're not converting to DNG, the settings in the sidecar are still effective, and they're applied by Bridge when it builds its cache and by Camera Raw.
If you made a Camera Raw settings choice from the menu in ImageIngesterPro, but not a metadata template, a sidecar containing only the Camera Raw settings will be synthesized.
