Help Wanted: A pitch-corrected Star Wars for PAL?

The alternative to pitch correct (time compress) the audio, also has drawbacks with audible digital "stepping" artefacts. Although Belbucus tells me the Serato Pitch 'n Time plugin for Protools has an extremely high quality algorithm.
@Pittrek: ConvertFPS will most likely damage your video (by adding a blur or "tear" to some frames). If you are looking to convert the framerate and keep the same duration, the DGPulldown method is preferable IMO.

GOUT image stabilization - Released

I think a saturation increase helps - my version had a bit more of a boost (1.15 as opposed to 1.08), but I also included a 6.25° hue rotation towards yellow.

Can't test the script at the moment so I'd be interested in seeing screenshots.

The gate weave, telecine wobble (whatever it's called) has always bugged me since the first time I saw Dr Gonzo's laserdisc rips. The image on the PAL laserdiscs does not wobble so much.

Adding still image to DVD

A moving clip would be more difficult, as you would need to manually animate a mask (rotoscope) for the silhouettes. It may be possible to do automatically if you could find a scene from a MST3K DVD where the actual movie is mostly white and the only black parts are the shadows.

But I suggest you try the still image approach first until you get the hang of the technique. Either add a subpicture with your DVD authoring software, as adywan suggests, or use AviSynth to overlay the image and re-encode the video.

Max_Rebo's '97 SE superset' preservation (* unfinished project *)

After mentioning the Flunk release in the other thread, I've also remembered there was another transfer called the Reivax version. Again, apparently it's a professional digital beta tape transfer, but I think only ANH was ever made available. I have no idea how the quality compares.

@wookielover69: Max_Rebo stated above he will be making both PAL and NTSC versions.

From what I've gathered, the plan is to make an NTSC version by combining video converted from the PAL with the untouched Dolby Digital track off the NTSC laserdiscs (although minor edits may be required if the DVB and LD versions have differing frame counts). I assume also that Max will be making a new 5.1 mix for the PAL version by speeding up the LD audio and re-encoding a new AC3 track.

Help: looking for... 1997 SE TB Digital Broadcasts

That's some bad MPEG artefacting in the GKAR shot above.

Have you investigated the quality of the Flunk version? It was apparently encoded direct from the digi-beta rather than a captured DVB source - potentially the best version yet - but unfortunately from the shots I've seen the image was corrupted in several locations. Still, it might be possible to replace the corrupted parts with video from the TB release.

Also, can I suggest starting a new thread for this discussion - titled "Max_Rebo's definitive '97 SE preservation superset" or something similar - rather than tack it on to the thread about the TB version.

I would hope so, since the third image is actually the untouched 1080p.

Here's a bit more explanation:
I found a frame near the start of the 2004 DVD and "zoomed in" on an area of fine detail - pic 1.
I had previously grabbed the first few RAR files from WG's post, so I was able to extract an incomplete 1080p WMV file. I found the same frame in this file, and downscaled the image to standard definition DVD resolution. I then zoomed in on this same area (pic 2) to compare with the image from the DVD. (Note this does not include the effects of further MPEG-2 compression you would have to do to make a DVD.)
Pic 3 is the same bit of the image from the unscaled 1080p file.

I don't know why adywan's downscale is showing an improvement over the DVD (I can't tell wether the improvement is real or perceived detail, due to there being slightly more contrast in the left hand image). Perhaps he was comparing a downscale from the original h.264 source, and maybe some detail was lost when WG re-encoded his version to VC1.

And before anyone asks "what's the point," a standard def downconversion from hi-def retains a LOT of extra detail and image clarity not present in a 480-line master.

I think someone posted a few screenshots demonstrating this using the 1080p files but I'm not sure if anyone has made and posted a DVD from it.
Since we can't locate the screenshots, I made my own:
