^ Post 19.

Wow, I'm silly. ^_^ Thanks for pointing out that post.

This is great work, schorman13 -- thanks!

I'm most interested in:

1. Star Wars 1977 Dolby Stereo (digital): Japan CLV (SF098-1103)
2. The Empire Strikes Back 1980 Dolby Stereo (digital): Japan CLV (SF098-1117)
3. Return of the Jedi 1983 Dolby Stereo (digital): Japan CLV (SF098-1100), US CLV (1478-80)

Has anyone here made any progress toward GOUT-sync'ing these tracks? If so, please share and thanks!

You_Too: This project is NTSC GOUT-sourced, right? If so, are you treating this scene in a special way when cropping away the black bars?

Thanks for the update(s)! This project looks great.

You_Too: Do you plan on releasing your modified script(s) for this project as well? To what extent is DJ still involved?

Wow, thanks! To what extent are these modified from their respective raw captures? Are most available on Myspleen?

It seems like many different people have independently captured the Definitive Collection. Does a list of these different captures exist? If not, let’s start one here!

This is, of course, a work-in-progress.

Captures…

Cowclops/TR47 V1
Cowclops/TR47 V2
Dark Jedi’s
Dr. Gonzo
EditDroid
Eraser
Farsight
ISOMIX
Kristhemovieman Dual Layer
Punk 13
Spider
X0 raw capture (ANH only)
 

Existing Capture (Re)Releases

Jedi/Feta (using Dark Jedi’s)
Row47 (using Cowclops/TR47 V1)

Despite taking the Leitch DPS-290 out of the mix, the capture-card seems to have duplicated <10 frames (yes, frames -- not fields!) in each capture. I'm working on manually identifying and removing them, as they interfere with my ability to line-up each of the captures to one another.

The following algorithm outputs ~100 frames for each capture, many of which are false-positives.

c.WriteFileIf("current_frame != 0 && YDifferenceFromPrevious() < 1.0",  "current_frame", append=true, flush=true)

I have a Perl script that takes the list of frame numbers and outputs AviSynth code to display: frame-1, frame, frame+1, red frame, .... Identifying the duplicated frames is then simply a matter of visually inspecting each segment and writing down the result. I plan on double-checking these results against something like MultiDecimate before moving on.

I don't know if this has been answered before: Are you making a 4k version, that will be scaled down to 1080p when you're done, or do you scale the stuff down before you start working?

Will you also release the 4k version for download (if you're making one).

I'm asking because I would try to recreate the Movietrailer for Star Wars in 1080p, but the Trailer was in 1.78:1, which means I would have to upscale the movie first...

we're scaling stuff down before working on it:

================================

http://originaltrilogy.com/forum/topic.cfm/Making-our-own-35mm-preservation-my-crazy-proposal/post/584238/#TopicPost584238

it's a lot harder to work in 4K..

the raw files alone would take up to 15-20 Terabytes

to hold the scan... i can't imagine how much bigger

the video would be.. instead of a 25 Gig disc, you

would have to use 50 Gig blurays, etc.. and unless

you had a really fast computer, you woudn't be able

to watch video at that resolution (i can't).

 

later

Do you (can you?!) plan to release a non-cleaned-up scaled-down version? It'd be very useful for those of us who'd like to play with the raw scans, but can't afford to send you 15-20TB worth of hard-drives.

What resizing algorithm do you plan to use to scale-down the images?

What you're doing is amazing -- thanks!

Agree, the less that's done, the better.

Agreed. This is why I intend to do two separate releases. Release v1.0 will be the median-of-five'd capture and Release v1.1 will be something that's comfortably viewable.

I also intend to upload each of the five raw and unfiltered captures individually to a.b.starwars. Many won't have the resources or desire to play with these, but you never know...

To resolve the issues with the Leitch DPS-290, I did five back-to-back (Panasonic AG-1980P -> Panasonic DMR-ES10) captures this past Friday night. These new captures are excellent replacements with no visible loss in quality and no randomly-frozen frames. Furthermore, the auto-tracking never changed since I did them back-to-back, so it's far easier to align these five captures than the previous five.

I looked at a scene from Interleave(c1.SeparateFields().SelectEven(), c1.SeparateFields().SelectOdd()).srestore(frate=23.976, omode=6, speed=-25, mode=2) and compared it with the same scene from GOUT. Amazingly, both are exactly 1063 frames. Some of the shot-transitions within the scene are off by one frame, but that can be repaired with AviSynth's FreezeFrame.

Should I still look at QTGMC?

Edit: Also, I was able to get rid of the ugly lefthand-side curve using DeFish(fov=48)!

You may want to try this out. It looks really good!

Warning: You'll need a *n*x box (e.g., GNU/Linux) with ImageMagick and NetPBM to run it.

Srestore is good for dealing with the most common field-blending issues, but this source is unfortunately too far gone to be restorable.

That sucks, but do you think Srestore might be able to do anything? I'm thinking something like: srestore(frate=23.976, omode=6, speed=-25, mode=2)

The Leitch DPS-290 must have caused more issues than just the occasional frame-freeze. I did a short capture using the Panasonic AG-1980P -> Panasonic DMR-ES10 and it does seem to have a pattern.

It's a 1600-frame Huffyuv-compressed capture, so it's a little large. I'd greatly appreciate any help with determining the pattern(s). Thanks!

Here it is!

There is no pattern I can see - it is most definitely field-blended, with some frames completely unrecoverable (much like the PAL VHS tapes of Droids and Ewoks).

Could this be caused by the Panasonic DMR-ES10? Probably not, as it's just a Line-TBC.

I'm currently looking into AviSynth filters for field-blending correction. Can you suggest any?

I can make the sample smaller tonight if the size is a problem for anyone...

Does anyone have a 1982 Video Rental Library VHS that they'd like to put through my setup when I'm done with PS78?

here's a clarification of the

machine and setup:

---------------------------------------------

I don't follow this thread often, but I do have a question. Are you snapping each picture by hand or is it automated somehow?

That's great information. Thanks!

What telecine machines were available in the late 70s?

Thanks for the information, everyone! Keep it coming!

I did some median-of-five experimentation yesterday with excellent results, but I think I'm going to try doing a capture without the Leitch DPS-290 before continuing down that path. If it's similar in quality to the others, then I'm going to redo all five.

The biggest problem I had yesterday was in temporally-aligning the captures to one another. I was able to get 3/6 to line up well. (Surprisingly, those were the only ones I did back-to-back; e.g., capture, rewind, capture, rewind, etc.) Considering that it works via frame-freezing, I think the Leitch DPS-290 is to blame.

I'll post an update tonight.

Sample 1 (9 seconds; 275 frames)

I'd like to apologize for the comment I made regarding others' interest. It was both stupid and passive-aggressive of me to say such a thing. It's no excuse -- rather, an explanation -- for me to say that the last week of my life has been terrible. As of today, things are improving.

This may be the most sophisticated VHS restoration of all time.

 

I wish there was some way to make it easier. This VHS exposes both the bad and good side of everything I throw at it.

I don't mind putting the work in, but I feel as though others' interest is waning :-(

Please define what's you mean by 'this'.  Are you talking about the IVTC process and merging of the captures or additionally the DeFlicker attempt?  The IVTC and merge, as long as the captures were done in one take should be consistent and the merge should return a better product.  But agree the DeFlicker would require each transition to be scrutanized.

By this I meant:

• Detecting and replacing the duplicates caused by the Leitch DPS-290
• Doing the Median-of-five on the now-duplicate-free clips
• IVTC'ing and GOUT-sync'ing
• Fixing the temporal luma variations (DeFlickering)

Very few have the resources to download one version, 5 raw seems overkill for the abilities of the people around here, maybe a small couple minute test piece first.  Then see what people say.

OK
