In order to achieve a rot spot free transfer, there is an AVIsynth filter called "TOOT" that will check three separate sources of video pixel by pixel and average the two most similar. So, for instance if I make three captures from three different ANH LD's and on one frame one has a rot spot and the other two don't, the output video will be without that spot. Using this method, I should be able to produce a transfer that is rid of all rot spots.


Got a link for that TOOT filter (google's got nuthin)? I'd like to test it out on some of my own captures.

Ooo maxy-bif this Farce!


It's true, that line is definitely still there - though he does make this stupid noise when Luke spins and points the blaster at him. Just one of those annoying new/changed sounds that Lucas insidiously injects every two minutes or so.

Info Wanted: Which OT DVD Preservation Has the Best Video Quality?
Time
I have the Farsight set as well as the TR47. I believe the color balance is a bit off on the Farsight (too bright.... loses some details in the white areas), and it is missing a few pixels on each side (compared to TR47 or Gonzo). As for bitrate, I think it's about tied with TR47 on smoothing and pixelation. Granted, there is more available bitrate for video since it it is only 224KB/sec DD (which btw I think sounds very good, compared to the TR47 pcm, which breaks up often), but the push could be due to other factors such as what sort of compression (if any) was used during the initial video capture and the quality of the MPEG-2 encoder.

Mind you the Farsight set is a great effort, but I still prefer the TR47 version for video quality.

Info Wanted: The laserdiscs vs. The best bootlegs

Sharp delineations are lost. Edges become softer, and objects with a range of colors (light brown to dark brown) have "bands" of colors, rather than a gradual change.


I think the smoothing effect and loss of detail during motion bugs me the most. Just look at the carbon freezing scene in ESB in any of the bootlegs. It looks like the characters are being attacked by ghosts instead of surrounded in steam. I'm hoping a high-bitrate DL version will improve upon this.

Info Wanted: Which Anamorphic Transfer is better?
Time
You can download it via BitTorrent from MySpleen.com. It's pretty good, but it is missing a few pixels of the original picture on each side and the white levels (slightly too bright) and the color balance (slightly blue, I think) are a bit off compared to Dr. Gonzo and the TR47 set. Dr. Gonzo has a weird "line echo" thing going on though... seriously, look at any frame, and edges within the frame are echoed lightly a tad to the right.

Which makes me want a multi-region DVD player, in addition to getting the Japanese uncut Kill Bill V1 DVD...



I'm not so sure about that, based on this, which was posted in another thread (click the pics to toggle between R1 and R2)

Can't say I have. I just downloaded the demo and tried to do a test, but it wouldn't let me use anything other than a DVD drive or an ISO as a source, so pffft. I'll PM you a (relatively) quick and easy way of doing it using AVISynth and VDub that you can try in case FairUse doesn't work out.

I have to agree with MeBeJedi. I think a hybrid DVD based on the 2004 release would not be so good. Even if LD footage of the changed scenes could be spliced in, the framing would probably be off, so you'd have to crop the DVD source slightly throughout to compensate or stretch the image temporarily. Furthermore, a lot of the changes are in the soundtrack and musical cues, so it wouldn't be just cutting and pasting frames, but trying rework the score in places. Finally, there are just too many little changes that GL made. If it's only the big ones that bug you, then fine - but when every new cracked out sound effect, orange explosion, digitally-added blinking light/distraction, or farting noise (see: right before the trash compacter creature appears) triggers a torrent of resentment at the man responsible for all this... well, let's just say I'd rather watch a blurrier, but consistent LD transfer.

No kidding!?! I never saw an XVID option (though I admit I never looked.) What about the audio? FairUse converted the audio along with it (I dropped the 5.1 from 448kbps to 224). I've always run the video by itself through VDM (The PCM is a separate capture)

Like Molly said, you have to configure it to use XviD under the compression settings. If you use 2-pass (which you should), you'll have to configure and run it once for each pass. As for audio, I almost never use VDub's compression options, even with LAME acm, because they are far less extensive than those provided by dedicated audio encoding progs. There is a somewhat decent guide on how to encode mp3 with Lame using BeSweet at http://www.doom9.org/ac3tomp3.htm .

All-in-one backup solutions like GKnot or FairUse are convenient, but getting to know the options of the programs they actually use, although time consuming, is better. I hope you'll eventually make the dvd image itself available, as, depending on the encoding settings and quality, even a 2 CD rip can fail to accurately reflect the strengths of the original source.

I saw it. Nice stuff. When I get to my hom computer (Man, my father-in-law's DSL is fast!), I'll give it a shot. One quick question: at first glance, it lookss like you hacve me running an AVIsynth in VDM. Is this the case? If so, why use this versus VDM's own IVTC?

True, you would be using VDub for the actual compression. The difference is that Decomb (I've found) has much better field detection and produces better results overall (it is also still being actively developed and improved upon, much more so than that aspect of VDub). I hope this helps

If VirtualDub's internal IVTC is leaving some interlacing artifacts, you could try Donald Graft's "Decomb" filter for AVISynth - I've had much more luck with it.

For me at least, interlacing artifacts can spoil an otherwise outstanding transfer (in the TR47 versions, see the brief lightsaber glitch just before Luke drives Vader off the carbon-freezing level in ESB or the more obvious full frame combing for a second when the Emperor is frying Luke in ROTJ), so it's important to find a setting(s) that works and to check the whole final product for errors. Please keep up the good work, MeBeJedi!

Hmmm, comparing the pics MeBeJedi has offered to frames from the TR47 version, it seems like the latter has better white balance. Some of the details visible in the TR47 version are lost in the brightness of those white-heavy scenes. Maybe this is something automatic gamma adjustment could improve during the capture process?
