As for the coruscant Scene, Ive used a technique known as datamoshing. Its how you get trippy music videos like this one https://www.youtube.com/watch?v=mvqakws0CeU.

The jist of it is that you remove the I frames from a mpeg video causing a video glitch. What I’ve done is rendered out the last frame of the HD source, a frame of black, then the SD portion of the source with the first frame being identical to that last HD frame. Then using Avidemux I remove the frame of black and the first frame of the SD source so that the following P and B frames reference the HD frame. What you get is basically the SD video wearing the HD video’s skin, not sure the best way to explain it.

Its not perfect and a lot more work could be put into tweaking it, it will only last a second of so but its enough to blend the frames over the gaps. Ive done it for the quigot shot and before and after the tower shot (playing the wipe transition in reverse to get the tower side of it, since the glitches only work one way).

Here are some comparison shots from the SD sources (4 sources blended together: two LD scans, Canal+ TB and ORF1 DVB) Compared with the datamoshed results. Also I did this multiple times with different combinations of sources and add blended several together to make the best looking image. Note the missing or garbled information on the edges, this will all be cropped out or filled in somehow.

I suspect that this is pretty close to the method that ZigZig is using. His look a bit better and he’s used a bit of edge fill in as well. Apologies if I stole your thunder… again.

Right now im working on redoing the subtitles, another pass at them might get them looking more accurate. I swear this release is comming out soon.

And in an unrelated note, I’ve started working on a new project that may be of use for star wars restoration. Imagine, if you will, being able to create whatever version of star wars you want, all with a simple formula.
