The part found is not from the recent explosion, it's from the CRS-4 resupply mission to the International Space Station that launched on 21st September 2014. See the Reddit thread here: https://www.reddit.com/r/space... The part is the interstage separator, a carbon fibre component that sits between the first and second stages. It stays attached to the first stage after the second stage detaches - in the case of CRS-4 it re-entered the atmosphere under controlled flight, and was videoed by NASA to gain information on supersonic retropropulsion: https://www.reddit.com/r/space...

This is true - in the repaired video, the rocket can be seen adjusting its course significantly as it descends towards the sea. The control software seems to be able to cope with it well, which is good!

No, codec was MPEG4 as explained by the author of ffmpeg!

Codec was MPEG4 in an MPEG-TS transport stream. The author of ffmpeg confirms it here.

Some of us can spare the time! Ask any questions you want, I've been fixing the MPEG-TS data in the file.

Hi, I'm the user "Princess" on the NSF site and I've mainly been involved with cleaning up the file at the TS level. I can answer any questions you like. The best summary for the Slashdot audience would be this one by Lourens, it explains things simply without dumbing things down. The types of problems we have are basically that bits have been either flipped or (rarely) omitted. The flips tend to clump together, i.e. you'll get an area that's good and then an area that's awful. The work is approximately divided into two parts: fixing up the file, and fixing up the video that results. I work on fixing the file, and from that I can find extra frames and pieces of MPEG4 data for the video people. Fixing the video is done by using a modified version of ffmpeg that can change macroblock pointers, ordering, luma and chroma. This work is not done on the file directly and can't easily be mapped back to the file, so it's not just a question of flipping bits once you get to the video level. Other technical info: The video itself is a broadcast (fixed bandwidth) MPEG-TS stream containing one video stream, a 704x480 MPEG4 stream at approx. 15 fps (technically half the NTSC framerate which is 15000 / 1001 fps).
