Just want to say this is an amazing job you guys have done! I had to drop out from doing it because real life intervened in my ability to have time to assist. Hopefully I'll have time to catch up on the some 30 pages that have been posted since I last helped.Just as a quick question, is there still need to repair I-frames? I notice that many of the I-frames have not advanced much in repair state from when I was last involved.
@arnezamiWould it be possible to add a option to manipulate the VOP-quant and vop_fcode_forward part of a p-frame header?Some seem to be messed up, and at least vop-quant seems to have a large effect on the whole frame. CheersShanuson
arnezami, could you post a patch? I was about to start doing the exact same thing . Hopefully the additional output will allow a kind of guided bit flipping, where we can quickly discard flips that yield obvious nonsense.
Here's an example of frame 94 with redrawn timestamps. The top part is the isolated pframe, the middle is the output from ffmpeg, and the bottom is repainted.Only the digits which are known with certainty are modified, so this should be a faithful representation of those pixels. The 1/10 second place is interlaced between 6 and 7. The last digit is not known, so it is left scrambled.

I'll put the current pages on archive and create new empty ones.
I adapted part 10 to the new ts, wasn't too difficult. I made a few correction on the way I think we should keep all the work put in the wiki with the previous ts files as an archive and create new pages with the new ts. Meanwhile I'll put the modification here.edit: forum does not like big gif it seems...

The 1/10 second place is interlaced between 6 and 7. The last digit is not known, so it is left scrambled.If the first decimal place is interlaced between 6 and 7 one would expect that the second decimal place is interlaced between 9 and 0. It does look like that. With the preceding or following frames is that not sufficiently certain?edit: Forgot to say that I am amazed at the terrific work people are doing here.

For example you can see that bits are missing. Thats not good . It's also very hacky atm. Will keep you updated.

Noting it as there's a small active team of people really working hard on this, but also a HUGE amount of people watching that work. Always nice to have a large appreciative audience, both inside and outside the space industry.You'd be astonished how many views are from IP addresses in a place called Hawthorne, California! I was curious how this thread ranked overall in the history of SpaceX threads (currently as of this writing, reads are (1) >180,000) so I sorted the other SpaceX dedicated threads and only the 100,000+ and Missions sections have threads that exceed 180,000. Currently this thread is the (2) 27th most read SpaceX thread and I think the NSF server (sorry Chris ) will explode when you all get the video restored "even" to the level of SwissCheese's latest gif (which is awesome BTW). see: Graphic representation of the historical significance of the work that the video restoration group is doing (see pic).Added: Updated context with consolidated "conversations" (multiple threads on same topic now rolled-up into a single "conversation").
