I know what I'd do:  actually buy SW Blu-Rays.

There's also http://www.blam1.com/StarWars/index.htm, and he has a site for Star Trek releases, too.

Question about the super resolution algorithm, does it require that the source originally came from something sufficiently high resolution, or can it work for things like home movies that were filmed directly on vhs tape?

I dunno.  It would have to be time base corrected to even have a chance, I think.

Yep! Also, consider the various PAL versions... they are good, but because PAL players are not high-end, your invention could squeeze a lot more quality from them!

I'm in the US so PAL isn't really available to me, but I do have some good PAL RF samples and every so often I make some progress on PAL stuff.  I think I'll look at it more this next week(end).

I'll probably look at http://mentat.za.net/supreme/ this weekend, which is BSD-licensed.  There are some single-frame and neural network techniques that sound interesting as well.

I was aware of this, but not able to use it... if this technique could mantain the promises as seen in the pictures, it could be the real winning one!

 Perhaps... I pretty much only use Linux, so can any of the scripts you or Dre use be ported to Vapoursynth?

Think to this technique used with your laserdisc capture workflow...

Oh I have been... :)  (If this can make the GOUT look this nice, imagine how JSC might look!)

Impressive... most impressive.

Good luck!  I haven't replaced an m-holder yet, but in general these last dual-side players are a bit less complicated, so your chances are better I'd say.  I think there are videos up on youtube.

Also you should be able to use a 515/925/406/606 service manual for the mechanical parts.

CLV disks don't have white flags - only the LD-V8000 even supported them on CLV, so there wasn't a point to putting it on any movie disks.  I've had good luck so far using ffmpeg's pulldown detection, which supports regular deinterlacing as a fallback.

IIRC they were planning to use the time compressed Star Wars master for the CAV version but they couldn't get the white flags right on it.  So the cadence is probably all wonky anyway.  The JSC is also known for being off, sadly.

The VBI data itself is pretty easy to work with - I have basic but imperfect sample code for the frame #s, and recognizing the white flag is trivial... getting it into a regular workflow is the problem.

On CAV laserdiscs, there is a "white flag" on lines 11 and 274 (or 22 and 23?) that indicate the first field of a new frame.  Also, the frame # is put in the first field.  MAME has some good decoding code for that.

So if you can get VBI data, it would be possible to automatically construct an avisynth pulldown script.

Unfortunately, the white flag data isn't on CLV disks, since the LD-V8000 was the only player made that could process them.  In fact, per blamld the speedup process used didn't tie in with white flag creation - Fox's original plan was to do a 4-sided time-compressed CAV disk!

If you're going to all the trouble to capture a lot of disks, why waste it by going through a weak sound card?  Get the cheapest card with digital input that has good drivers that don't drop or mangle samples, I'm not sure what that *is*, but it shouldn't be hard to find a used one for a reasonable price, especially used.

According to blamld the VHD version was not time compressed (nor was the 1983 Japanese CLV)

The MAGVID3 line's a nice little echo of Magnetic Video... maybe they had forgotten to switch one of the duplication lines then?
