On a side note... regarding the referenced Color Finale Pro, and their new product Cinema Grade in the previous post... these are only desktop grading solutions, but the new Cinema Grade product looks like it could be very touch-centric.
I originally paid about $30 for their (Color Grading Central) LUT product that allowed importing of LUTs into FCPX. Then I bought into the Color Finale Pro product for another $75. Truth be told... I don't really use it that much, because the new tools in FCPX are pretty much enough for me. Creatively, sometimes I like to import an interesting LUT in and then tweak it to taste. So, hardcore color grading isn't really that important to me at the moment.
The reason I mention this and the extra background, is that when they launched Cinema Grade a couple weeks ago, I might've paid for it again. Given how little I use it, I couldn't justify spending another $100 on it. If it'd only been another $30 to upgrade, I might've bought it anyway, even though I don't really need it. And, if they had an iOS version of it that somehow worked with Lumafusion, I likely would've paid for that.
The only apps I have on the iPad for grading are VideoGrade... which is decent, if not a bit basic. And the other one is Video LUT, that's actually VERY good and has LUT import/export support. I don't think it's very well known, but that developer Katerina Alieksieienko makes very impressive graphic & video apps. Her main focus is iColorama... but her lesser known apps are impressive.
Here's a link to her excellent video grading app: https://itunes.apple.com/us/app/video-l ... mpt=uo%3D4
If the Lumatouch team is weighing different add-ons that aren't necessarily needed as part of the base app, but could likely generate more in-app revenue... I think a good pro-level grading solution that could seamlessly integrate within Lumafusion would be a good option.
