Just one ESB shot fixed, but I'm pleased with it and thought you'd like to see it

You’re right, the X-wing should be darker than I’ve made it. The trouble is that that would mean keying around more of the stuff on the underside, which is fiddly.

The trouble with compositing anything in from the GOUT is that the composited elements are in completely different positions. Also what little additional detail may be there is low resolution and quite smeared by compression.

The change in the last video is Yoda.

This is the shot of Luke’s X-wing floating over the swamp, which they really messed up for the Special Edition. The original shows light filtering through the trees on Dagobah; for the Special Edition, they darkened that light almost to nothing, which not only means you can’t see most of the matte painting, but also makes it look like night above and daytime below (so unless Yoda has a floodlight system installed in the trees, it makes no sense).

Luckily the matte painting is still there, it’s just very dark. I brought the levels back up, but then the X-wing was a bit blown out and needed rotoscoping so it could be brought back down. I ended up writing my own rotoscoping software, because the outline of the X-wing isn’t clear enough for any of the normal solutions to work.

As the work-in-progress had some interesting looking graphics, I thought I’d try and make a little breakdown of it, which is linked at the top.

Request: recreating a trailer and need some HD shots from the OT
Time

Hi all,

I hope this is the right place to ask - I’ve been gone a long time…

I’m recreating my favourite Star Wars trailer in HD using the Blu-rays, but two shots have been too Special Editioned, and I’m hoping someone could help me get hold of the original versions of these shots in as high a quality as possible.

They are:

  1. The wide shot of Luke’s X-Wing floating towards him after Yoda lifts it out of the swamp (https://www.scifibloggers.com/wp-content/uploads/empire-Xwing_l-300x225.jpg)

  2. The final explosion of the ROTJ Death Star (with the Falcon flying towards the camera in front of it)

Can anyone help me with either where to look, or with actual files of the shots in question?

Thanks,

DE

My Doctor Who trailer/montage... thing
Time

It's only just occurred to me that there are more than a few Doctor Who fans on here who might be interested to see a montage I made last year from the first six seasons of "New Who."

https://www.youtube.com/watch?v=GZfU9olGiiE

(why I can't linkify it, I don't know)

It was edited entirely with Avisynth with perhaps just a couple of bits of Photoshop to alter one or two things (points to anyone who spots those).

team negative1 - star wars 1977 - 35mm theatrical version (release details and updates)

I remember years ago, shortly after the release of the GOUT DVDs, a member of some other forum saying that one day a really dedicated Star Wars fan would get his hands on a 35mm print or two and go about making his own restoration. I never thought I would actually see that but, shit, here we are.

Mike Verta's being doing just that for years, hasn't he? The caveat of course is that he was never going to release it...

Well it also depends which matrix (if they went through a conversion to RGB at all) the frames were initially decoded with, of course. What you tell the encoder doesn't make any difference to the encoded video data if it's being fed YUV (as most are); it's just a hint stored in the container which will hopefully be taken by any eventual decoder. I've always got expected results out of YouTube if the video encoded was matrixed from RGB with rec.709, incorrect results with rec.601, and no knowledge of any other way to confuse colours.

Out of curiousity, are any of the wrongly-coloured ones (with a corresponding correct version on Vimeo/Facebook) still up on YouTube?

That image still looks nice though. I like how sharper it is comparing to original.

You could take any frame from any blu-ray, sharpen it, compare them on a computer screen and it will look "nicer." It doesn't necessarily follow that you can make a better video that way, though - it's a bit like the loudness war for video, with the added complication of wasting bits encoding sharpened pixels which your TV could have done for you at no cost.

Well, I usually edit from lagarith avi converted directly from the raw m2ts file, but here I just used VLC to take snapshots, as this isn't a project I'm directly working on right now.  That might be the issue, if it's not how do I make sure it's rec.709?


You could look into using AviSynth via VirtualDub, which will give you this kind of control, and in fact has all kinds of tools for colour correction without converting out of the original colour format. Your Lagarith AVI is probably still the same colour format as the m2ts, but I guess VLC is using the wrong matrix on playback.

If necessary you can convert to the correct matrix using an RGB channel mix:

r' = 1.08r-0.07g-0.01b
g' = 0.10r+0.84g+0.06b
b' = -0.01r-0.03g+1.04b

On another subject, I must say that I think you've massively over done the sharpening. Video is often a lot softer than people think, because displays (i.e. TVs) are expected to have some kind of sharpening. You'll also hurt your final compression ratios.

And yes, there is actually more detail there...
...the edges are crisp because of added detail...


I'm not clear what you really mean - adding noise may make it look more detailed, but there must be less information than before, unless you've actually gone in and painted those details in yourself.

It looks to me, based on the unaltered screenshots, like you've started off with video decoded using the wrong colour matrix. See this:

http://screenshotcomparison.com/comparison/40082

The "over" image is the raw BD correctly decoded with the rec.709 matrix.

Possibly not a massive deal if you're colour correcting everything anyway, but HD material should always be decoded to RGB with rec.709, not rec.601.

I sometimes wonder if a small part of the complaints about the colour of the blu-rays is down to this.

It's also why Ady's videos were the wrong colour on YouTube. YouTube always uses rec709, both for SD and HD (it should only really be used for HD). My guess is his videos were (incorrectly) encoded with rec601, which would then look fine on his player (some, again, incorrectly use rec601) but would be wrong on YouTube.

go-motion before which is the new techniques of adding motion blur to improve the quality of the stop motion either by flicking the model or creating vibration on the surface it was being shot on or the computer controlled rod puppet


Go-motion is the use of a computer-controlled rod puppet which moves during exposure of each frame, so it's accurate motion blur. No flicking or vibrating involved.
