Reading about this amazing sounding software, the new Metabones adapter, RED's plans for indie 4K distribution to theaters nationwide all in one week's time...am I dreaming?

Did you mean with "videos" original out-of-camera MTS files from hacked GH2?

Of course, I found some originals from Vimeo Plus downloads (MTS, mov) and from other forums. Currently I have a huge collection of many camera original files. They are from unknown license, so I cannot use them to share. I have my own videos from my NEX-7, but, anyway, I will publish any final examples after a stable release. Because internal algorithms are still under development and real finish quality is not stable now. Also huge lossless video needs a lot of server space to keep these files. So I don't want to publish any results now. Currently the program is available for public less than 3 weeks...

@matt_gh2, yes, you do it before, since once you've imported it into Premiere and edited, this information is lost. So you do this similarly to how you do this in 5DtoRGB or in Cineform. It's not about the floating point thing, it's about rescaling the channels.

About the actual theory, I don't feel qualified to tell anything, I'd better redirect you to these articles:

Hello, I am the developer. zsero invited me here. The program is not for upsampling really, but it may be used for this thing. It is planned as any camera quality restoration tool. I used some internal versions within last two years for my own commercial videos from a low bitrate camera (17mbps H.264 4:2:0) and currently with Sony NEX-7 (28mbps H.264 1080p50). Currently I have planned to share it with a community. So a new version is developing with some useful things.

Restoration includes:

• H.264/MPEG/MJPEG codec artifact fixing (dithering, deblocking, motio-compensated denoised and other tricks).
• Other camera things fixing including color cast, digital noise, halos, oversharping, etc).

Also it is useful as a service tool to rename and batch convert original clips from a camera and from a sound recording device. Internally I use it to make films. It supports 1080p by a design. And... upsampling is really a small additional feature.

I tested an oldest internal version with many videos, from the internet, including latest Sony cameras, Panasonic x900, GH2, GH3, Canon and Nikon DSLR. I always get great visual results even with a 100mbps videos from hacked GH2. Sorry, I cannot show you any result now, because have no GH2 and licensed clips.

Currently the program is under development. Really I working every day a week with it. After a stable beta version will be ready, I will publish examples, screenshots, videos, html documentation, etc.

If you have a question, ask be here. But I am really very busy now, because hard coding Windmotion now, so I apologize in advance for not being able to answer multiple questions or clarifications.

I don't recommend anyone to download Alpha 2 version now, because you will get a next published version very soon. It will be a big different to use. Also, I would be grateful for permission to use your video from hacked GH2 or other cameras. I am particularly interested in high bitrate samples. These samples will be used to create examples and a documentation.

It could stand to have some documentation. I got a Windows 8 VM running, installed the necessary apps/codecs/scripts, but you end up with a folder full of batch files for each individual process and not much idea of how to go about processing footage. Plus several of the scripts aren't included in the beta because they are for the paid pro versions.

Edit: Nevermind, I see he already has a GUI going in the newer version. Good luck figuring out the alpha ;)

@zsero Have you installed and tried it?

Interesting. Maybe I'll fire up a Windows 7/8 VM and try it out.
