I wish someone like the creator of Curiosity Descent footage ( http://www.youtube.com/watch?v=Esj5juUzhpU http://www.youtube.com/watch?v=Esj5juUzhpU ) could get their hands on the three separate RGB channels and combine them manually. The frames did not seem to be overlaid properly and combining 1R + 2B + 3G as 1F, 2B + 3G + 4R as 2F etc. caused offsets in every frame.

That Curiosity descent video was amazing. Here's an even better side-by-side with "director's cut" captions explaining what's being done: http://youtu.be/pjeHZ9poew4 http://youtu.be/pjeHZ9poew4 Thanks for sharing. But in answer to your question - the RGB channels are there - you can download the h264 vid and decompose (sure, you'll some quality, but that's not the real blocker). The real issue is the time - if you believe him, the Mars Curiosity guy says it took him a month to pull that off: "It took 29 days from start to finish, working full-time on it for the last week. This was the most laborious media project that I’ve ever done. But I don't regret a minute of it. ", so you'd have to convince him to do it.. But you can probably PM him on Reddit if you're serious enough ;) http://www.reddit.com/message/compose/?to=bard_canning http://www.reddit.com/message/compose/?to=bard_canning

  Hm, maybe he could fund a full restoration with Kickstarter...

    That's actually not a bad idea... the footage does appear to be quite long - and with having to stabilize the three RGB channel frames separately it would take three times as long. I would probably have to put aside a significant chunk of time in order to get it done. People have been so amazing and supportive of the Curiosity video - I might just give it a try! It would certainly be a big project - but wouldn't it be amazing to make the first ever color movie crisp, clear and stable!

      I certainly hope the project gets back to you - if they don't, you could kick it up a notch by writing a quick blog post or something describing who you are, what you want to do, and getting some social media publicity spun up. I can see the Reddit headline, "I'm the guy who restored the Curiosity descent video and I want to restore the world's first color film" - karma gold. If you did start a Kickstarter campaign, I guess you wouldn't really have any swag like shirts, early copies, etc. like they usually offer. But it shouldn't be a problem, I really don't think you would have any trouble at all getting funding, considering your reputation and just how cool this would be.

  Thanks - someone just did which is how I found this post.

    Great job! really amazing what you could extract from that footage!. There is only one thing that I find could be improved a bit ( I am no expert by the way, just a video aficionado): at 1´50" when the jet from the rockets hits the floor, you can clearly see that in the original footage but you can not in your version till 4 or 5 seconds later, but the impressive first burst is lost(I imagine that is a trade off of the morphing). Any way really impressive work! Nasa must hire you!

    So you 'only' applied 2D interpolation, if I slightly understand what motionflow is, and it restored so much information ? I thought it was a 3D aware superresolution algorithm like I've seen used for space probes.

You could tempt him with the thought of putting "Full HD color film from London, 1902" on youtube and mean it.

Should be plenty of papers on the Prokudin-Gorskii images on how to overcome this.

I think much of the color bleeding is due to the colors being shot at different times. Prokudin-Gorskii images have color bleeding and most of the subjects photographed are static and still. Motion interpolation and color enhancement is a bit different than merging the RGB channels from different moments in time back together. It's similar to deinterlacing fields of video together to make a progressive frame. Results can vary and artifacts will probably still exist when there is a lot of motion. I guess one could attempt to get a luma(greyscale) version of the film together using the different channels and then attempt to fill in color using approximations. Sounds like a lot of work.
- bardcanning 14y ago
  Right, but I would be willing to do it.
  - Klinky 14y ago
    I'd love to see what you could come up with. I see no reason why they couldn't provide the raw films to you given your reputation.

One should also not discount the possibility of emulsion damage. There might just be some damage to the light-sensitive material or the original substrate.

Hi - the creator, Bard Canning here. That's actually a really great idea. I've emailed them about it. But, I'm not going to hold my breath. They don't appear to know much about post-production enhancement methods, etc. The "advanced" post-processing by the company shown involved nothing more than rendering the frames as a movie. They appeared to have done nothing at all to stabilize the individual RGB frames or to correct the histogram or color balance. I wouldn't want to attempt this by de-converting the video footage - it would just be too ugle and low-resolution. But here's hoping that they allow me access to the original frame scans. Thanks for the great idea, guys!
- phreeza 14y ago
  I agree that doing some more advanced post-processing on this would be great, seems the quality could be a lot better. Perhaps look to the restoration of 'A trip to the Moon' for inspiration of what might be possible. What are you the creator of, by the way? The video clip? Good luck with obtaining the frame scans. EDIT: OK I see you are the creator of the curiosity clip. Amazing work! Hope you can pull this off, I would pitch in on Kickstarter.

"To license the use of images or clips, please contact Science and Society Picture Library." That's unfortunate. If they released the raw digital data to the public, I bet someone out there would take it on themselves to restore it much further.
