If everything goes as planned, SpaceX will launch again in a few days, and I think they're planning to attempt recovery again. This could upstage the (arguably more historic) first landing video. We need to put together a video with what we've got today, tomorrow at the lastest. If necessary, I can hand-assemble something from the iframes and pieces of the pframes. It wouldn't be as pretty as what arnezami and mlindner can do, so I'll wait until I hear from them.It's actually a lot easier than that. If no one else does it by Friday Eastern time then I'll be modifying ffmpeg to add a frame specifier to the mmb options. Then we simply pile all the mmb options into one long entry and run ffmpeg with it. viola, produced video. This would also allow us to try tweaking some p-frames if we so wish.Producing a video now with what we have won't be very attractive yet. We need to fine tune a lot of the frames still. I'm doing that now for iframe8, which should hopefully look really really good. This means doing things like whenever you use -1 and replace the block, fine tune all the luma and chroma settings for it to have the least effect on surrounding blocks.Are you still planning on doing the frame specifier modifications tonight? Right now we have mods for two different video streams. Are you going to be able to integrate those, or do we need to start a porting effort to a newer reconstruction?I think it is likely that it could take weeks or months to get the video to a level of quality that is going to satisfy everyone working on it. Chris, can you ask PAO what timeframe would be most useful to them?

Chris, can you ask PAO what timeframe would be most useful to them?You guys are ahead of the game, the only real game in town actually. Provide what you can, when you can. This is an unbelievable effort on show here.

Can we create a .gif, showing the original frame8 and the one above, with before and after written on them?The .gif needs to be 350 pixels wide and whatever you require in length and then I'll use that in the article I'm going to put on shorty.

Rampant speculation about something "damaged" when it could as easily be a video artifact or misaligned video data block is why Elon and SpaceX are leary about releasing such things in the first place. To me the anamoly it looks like it has right angled edges which align with the macro blocks. Let's not get too crazy about this yet.
I don't know how much "better" such video would be. On another site I saw a claim that the telemetry plane on CRS-3 was over 20 miles away. The CASSIOPE launch aerial images released also suggest a pretty large distance from the vehicle. I guess safety trumps closeup observations.

This is an unbelievable effort on show here.This is truly an d unbelievable effort. And is amazing to see the amount of details that have been recovered form the initial frames, and the conviction and talent of all people that have been involved....This is what we have so far guys! And let's keep with the good job:
Chris, may I recommend you add links to the first post of this thread detailing how to start helping with this effort and some of the better posts in the thread describing what's going on? I think it will help orient people without going through 24 pages of stuff.

And let's keep with the good job:Great! I was about to ask for something like this. Or make it myself. One suggestion/request: a bit slower sequence? Either more realistic in terms of actual movie speed or even slower to be able to find common blocks?
...Just curious...The original releases (raw and 'repaired') had frames as the stage was descending through the cloud layer which fit before this sequence, and the stage falling over at the end which come after -- both best seen in raw IMO. Are those frames somewhere in this amazing recovery effort?Link back to OP:http://forum.nasaspaceflight.com/index.php?topic=34597.msg1191316#msg1191316

I think it will help orient people without going through 24 pages of stuff.I'd rather people read through what is only 24 pages. It takes 5-10 minutes to read and new people to the thread will gain an appreciation of the work and the processes involved.
