GH2 Cineform Question

Will this program (http://cineform.com/products/gopro-cineform-studio-premium#overview) work to convert GH2 AVHD files to have a higher dynamic range, allowing the footage to be more heavily color graded? From this tutorial (http://www.henryolonga.net/Blog/?p=1365) It looks like it should work, but I wasn't if anyone else has tried it out.

Filmmode Settings Tests: detail handling, color shift, exposure, etc.

There's been a lot of discussion about which film mode setting is "best." Usually these discussions are a mix of personal opinion coupled with claims about what setting appears to the perceiver to have more dynamic range. I want to discuss the differences between film modes in a more objective way.

So here's one thread to start that. If you look at the pictures attached, there are four blown up frame grabs (from video, not still). They are: Standard, Cinema, Nostalgic, and Smooth. These all have the same white balance setting, shot with same lens, aperature, shutter speed, and lighting (a practical floor lamp). The picture profile settings are at 0 for everything except sharpening which is -2. This is pre-hack.

There are few noticeable things.

One thing in particular stood out to me, which I don't think people talk about. Look at how highlight and midtone *DETAIL* is handled on mode.

1. Cinema captures more highlight detail than the other settings--the wall on cinema has detail that was actually there, whereas in the other modes there are patches of white mixed with wall detail. These patches aren't blown out highlights!

2. At the same time Cinema captures midtone detail pretty poorly relative to the others. To see this, on the phone jack panel to the left of the phone jack. There are smears there in nostalgic especially that were present, but that cinema doesn't capture.

3. Nostaligic also has a pretty bad color shit to yellow (with a touch of shift to red) as you can confirm by a waveform.

4. Finally, it's worth noting that to achieve comparable exposures in each profile, one might need to allow for a bit more light in cinema and a bit less light in nostalgic.

Thoughts?

I've also been curious about what @cbrandin has been up to with his film mode research (or whether that's petered out).

EDIT: color shit = color shift :p
