Since i now see the app is basically a shell script, i'm thinking about implementing dcraw and ffmpeg. Dcraw for make tiff out of DNG and ffmpeg to make Video from tiff. I have tinkered the last Days with them and Automator, to batch-convert them.
But there are some issues for me... I'm not familiar with Menu builder (or how its called, the thing to make UI), and it would almost need some UI for it, out of following reasons: for dcraw i would like to set at least the WhiteBalance. Automatic does not work well enough. But this would almost require a preview of at least one DNG file. Other variant would be to have only setting for Tungsten, Daylight and others. (Kelvin would be a bit difficult sine draw does not have Kelvin, but RGB multipliers).
for ffmpeg it would make sense to be able to choose Codec or probably some Preset Codec/Container combination. (ffmpeg shell execution is quite complex, and i'm not a programmer myself, except some basic Shell/Phyton)
About xcode menu builder. Since you have used it somewhat, what you think about it? Is it difficult or relative "easy" to learn? I'm willing to spend some time. Just let me know what you thing about it there.
This for now, and now some questions:
1. Is somebody already planing an app to do this?
2. How do you feel about having this in raw2dng app? Should it be a separate app? (I think it kind of makes sense to have all together, maybe with options to do DNG and/or Tiff (or jpeg) and/or Video.)
3. Do you think there will be World Peace? ;-)
Well, let's see...
