Star Wars SWE LD (Technidisc) preservation (Released) — Page 2

This is all very exciting, csd79! Unfortunately, there is so much compression on that dropbox clip, it's hard to gauge any quality from it.

I Look forward to seeing the fruits of your hard work!

I compressed that clip with x264 crf 17, so the final DVD will not look any better I'm afraid.

ElectricTriange: Yes, that is the temporal filtering. I might try to redo the first desert scenes with lower settings. It's not an easy thing though, because those parts are the dirtiest in the whole capture (besides that speeder flyby shot in Mos Eisley).

 Good to know. To be honest, I don't mind dirt and noise all that much, but the noise reduction was tastefully done.

I don't mind it either. I agree the noise reduction looks pretty good. But I'd love to see it unprocessed with original grain, dirt, rainbows etc.. Maybe with the bad frames fixed, color levels adjusted, etc.

Oh. It's probably the noise reduction then. That's too bad.

 Yeah, it's not that I really "like" the rainbowing. I just prefer it to the processed look. The biggest strength of this source is the unprocessed film like quality it has.

I actually do like the dirt, grain, and minor flaws that make it feel like I'm watching film.

I made a quick comparison clip with huffyuv, to demonsrate what is lost with all the filtering. Personally the only negative I can see is the loss of percieved sharpness caused by NNEDI, but obviously everyone has his/her own preferences. With Msycamore's new version and Poita's capture, I guess eventually everyone will get what he/she likes. :)

Re-examining the avs script for this scene, I realised that noise reduction was already lower than it was for most of the rest of the movie.

Thanks, especially for posting the script.  You're putting a great deal of work into this.

Are you using the BD to guide your correction of the AR or relying on PAR?  If you're planning to release a DVD, consider keeping the nominal analogue blanking and resizing only vertically.

Are you using Moth3r's guide to inform your color correction or following personal preference?

The final image size was simply calculated based on the numbers in the PAR article on Wikipedia. Before resizing there is anti-aliasing with NNEDI3, which doubles the image size vertically. I tried to do the final resize with and without keeping the side bars and since I couldn't see any difference in detail, I cropped them.

The basic color correction is inspired by Moth3r's method, but I didn't really calculate anything, except for the chroma shift, but those are both less then 1.0 so I only included them in the script as 'notes'. The rest of the tweaks were made by comparing the histogram and vectorscope of the disc's SMPTE pattern to those of the standard color bars generated by Avisynth. In the following images, the sharper readings are those of the standard bars, and the pale overlay represents my capture. Raw on the left, corrected on the right.

Both luma and chroma comparisons were made on the first frame of the color bars segment from Side C. I noticed that after the first frame luma contrast starts dropping, until a couple of seconds later it stops. Meanwhile the chroma stays the same. I did the tweaks with the first frame (highest contrast) because its white level corresponds with flash frames from the movie better. The next image shows the fall of contrast in the color bars pattern on the disc.

Thanks for the info, csd79.  I'd still recommend keeping the nominal analogue blanking (sidebars) for the DVD, but it's up to you. :-)

It puzzles me that the problematic fields show up in some captures but not others.

That's true, and it is puzzling, but I received the impression (from post #24) that csd79 meant different captures of the same disc, rather than differences between captures of different discs/pressings.  Perhaps I misunderstood though.

Sorry guys for the confusion, probably my explanation could have been cleaner. Those bad frames occur within a ~8sec period, so I think there might be some minor damage on the disc that causes the player to loose track sometimes. The frames could be repaired completelly by shifting the right field vertically back to the right position (there was one frame where both fields needed a shift).

Here is the pattern of their occurance:

capture 1:        45714 45739, 45756,               45805, 45829, 45846 45871
capture 2: 45691, 45714 45739, 45756, 45763, 45780, 45805,        45846 45871
capture 3:        45714 45739, 45756,        45780, 45805,        45846 45871
capture 4:        45714 45739, 45756,        45780, 45805,        45846 45871
capture 5: 45691, 45714 45739, 45756, 45763, 45780, 45805, 45829, 45846 45871

(This should be viewed with a non-proportional font.)

So only capture 5 has all the bad frames. IMO this is not a difference in pressings, this is just some problem specific to my copy.

So, this project silently evolved into an obsession with different transfers of the trilogy. I ended up buying one issue for every transfer that ever got released in the US - 5 for SW, 3-3 for the sequels. The I got a different capture card, re-captured the whole collection at least once, some versions twice…

I had the idea of synching the different versions to the most complete one - that is, the Faces LD - and muxing them into a single file as video tracks. So you can switch between the different captures while watching the movie. Then, when I was almost finished synching the audio tracks I ran out of gas somehow, and the project lay dormant for almost two years. Then I moved to another country…

Now the whole thing is finished, but I don’t know how to share it yet. My home connection is crappy, so P2P is not an option. But meanwhile, I figured I’d upload the Technidisc version to Google Drive in case anyone’s still interested. All my captures are filtered so sorry if it’s not your taste. But anyway, PM me if you want the whole file (1.4GB). The audio track is the '85 home video mix.

And just to give you an impression of the multiple video track-thing, here is a sample from what I call sw-gsd (Star Wars in Glorious Standard Definition): https://drive.google.com/open?id=1TQYd9pNwRJTInFU4qLvfBOC8lYWMDcMR
MPC-HC has great support for multiple video tracks.

Hi csd79,

I love the idea of being able to switch from one version to another, it is soooooo niiiiiice! Thank you very much!
About the capture, is it still based on a CLD-2950, or have you upgraded your installation since 2014? What post-treatments (comb filter, IVTC, etc.) do you apply?

Cheers!

Hi! At the moment, only the Technidisc track is uploaded, as I don’t have enought space on Google Drive for the whole thing (but I will soon). As for your other questions, check out the text file under the last link to learn how the sausage was unmade. 😄

Update: I upgraded to a more spaceous Google Drive account, and now all my captures are available from there. Also, althor1138 kindly offered to put them on Spleen & Resilio.

How come there are no subtitles included?

It is a LaserDisc preservation, there was no subtitles on the discs that csd79 generously preserved…

JEDIT: Maybe the project Threepio would help you: https://originaltrilogy.com/topic/Project-Threepio-Star-Wars-OOT-subtitles/id/13794

Back when I did the bulk of the work, I was planing to include subs, and then I forgot about it. Obviously all the discs had subs for the alien language bits.
