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."

(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...

OBITUARY - Star Wars Fullscreen/Pan and Scan versions. R.I.P.

For what it's worth I've taped together more than a few VHS tapes in my time, and never had a problem. Obviously you'll lose whatever you've lost, and tracking will probably go awry for a second or too, but as long as you've been neat there shouldn't be a problem when it goes past the head.

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.

A New Hope DVD Color Correction (Video Now Available)

Digital video luminance levels are stored in a range from 16-235, or something like that, and when decoded/displayed should be stretched out to 0-255. Looks like something didn't work right somewhere in the chain.

Matte paintings/scene recreations original trilogy help
Time

This:

http://www.amazon.co.uk/Limited-Edition-Star-Executor-Collectors/dp/B000QVT2PM

came with a bunch of them printed on glossy card, though I don't know how well they might scan. If I remember rightly, there was the Ewok village, Jabba's Palace, and Slave One parked up on Cloud City among others.

But they all had black spaces where the live action would be, which is of course how matte paintings work.

Michael Arndt heavily involved in writing the new SW trilogy

Wow, this seems to me to be a tremendous and original insight into the success of Star Wars. Thanks for posting this.

I never thought of it like this. It still raises the hairs on the back of my neck when Han reappears, and I still breath the same sigh of relief as Luke.

There are similarities with - off the top of my head - Stardust and Fifth Element too. The emotional (internal) resolution directly resolves the external threat. Both are endings I've always enjoyed.
