OK, to give credit, where credit is due, I have to say that some of it is partially Adywan's work. Let's break it down, shall we?
For this shot I had to remake the wipe and in order to make it fit better with the HD footage and get rid of the horrible DVNR ghosting in GOUT, I used photoshop to recreate the original background as a still picture using the GOUT and the parts from the SE that were the same as the original and then rotoscoping in the speeder and it's shadow in from GOUT.
This shot is the only one for which I had to use just upscaled GOUT, because it was altered beyond recognition in the SE.
This shot was masterfully recreated by Adywan for his ANH: Revisited, but sadly only in SD, so I only used the part where the Ronto walks in front of the camera from Revisited and used this guy in the grey cape as a transition between the SD and HD footage. In this still picture you can see there is a slight difference in the colours but in movement it all happens so quickly that it is pretty seamless.
This shot was the toughest one. I originally thought that I would just use Revisited for it but Ady seems to have used the background from GOUT and rotoscope the stormy in from the SE, but the GOUT shot is pretty bad and he probably had to match the grain on the stormtrooper and also, and that I don't understand, it is cropped even more than the GOUT shot is, so it doesn't look so great in ANH:R and especially when put together with HD footage. First I tried rotoscoping the flying droid out using GOUT but the quality difference was just too noticeable, so I ended up using photoshop to recreate an empty HD background plate which goes to the very edge of the camera movement on both sides and then animating its movement in AE to follow the camera movement in the shot and rotoscoping the stormtrooper into it in detail. When this was done, I exported the whole shot as a sequence of BMP pictures and fixed the little details in Photoshop. It's still not perfect but I think it looks pretty good, especially when put back into the film.
Once again this shot was already done by Adywan in SD but because it was the same transfer, it was quite easy (as in: it only took about two hours) for me to rotoscope the ANH:R footage into the HD transfer.
This shot was done by rotoscoping the SE HD footage and GOUT together. I used three different masks: one for the Ronto, one for the shadow under the speeder and one for the R2 droid when the speeder passes it. It was really dificult to match the colours of the two different sources and although I used a few different filters on the GOUT, the transition is still quite noticeable. But I think that overall the shot looks better than in the GOUT.
I rotoscoped the Ronto out of this shot using the GOUT. It was quite an undertaking to rotoscope around the foreground characters but as the quality of this shot isn't so bad in the GOUT, the result is IMO quite satisfactory.
