I was going through my hard disc trying to clear some space, and I found an early experimental shot. I won't post it on the X0 site as I never finished it, there are more things wrong with it than I can count, but rather than just delete it, I thought I might as well throw it up here anyway, as I am busy programming at the moment, and there won't be any current screenshots for the next week.
So you guys will have to make do with this throwaway shot in the meantime.

Get a card that has a proper video output, or go on the cheap and get a realmagic card or something like that so that you can compile a file and watch it on your TV.
First things first though, calibrate your monitor and your TV with some test patterns at least.
The calibrate your capture system to make sure you are capturing the full dynamic range of your source. (ie. that it is no too bright with blown out whites or too dark with crushed blacks)
If the source is still to bright, then set new black and white points.

Start downloading nothing.

Seriously maybe grab limitedsharpen and have a play, but get to know how the programs work *first*.
Try getting some footage, applying say two filters to it in vdub, and then play with the filter settings and see what happens. The try the same thing in avisynth. Try changing the order of filters and see the results.
Get a grounding on how both programs work first by just using a few filters.
Once you have your head round it - *then* download another filter or two and see what they do.

For this sort of work the things you may want to do with footage is:
adjust the black and white points
noise removal
sharpening
resizing
colour correction

at least to get started anyway. so grab some filters that relate to those and try them one at a time, get to know them, see which you like the best, then see what order they work best in and so on.

I guess what I am trying to say in my waffle is don't get caught in the trap of being a 'collector' of apps and filters, pick a small selection of software, then start using it and learning it, and don't download anything new until you understand what you already have.

I would tell my student to open up her browser and go to...

Honestly it is the best place for this stuff. If you want to use the free programs like AVISYTHN and VIRTUALDUB, head over to their forums and search first, then ask away.
I'd almost bet my left nut that any question you have is already answered in the forums, so make sure you spend some time searching first.
Learn avisynth, it is worth the effort, but you need to know virtauldub too, so maybe play with some of the virtualdub filters first to get your head round it, and then try applying the equivalent thing using avisynth as an experment an see how you go.

Info Wanted: Definitive Collection versus Faces - which is better and why?
Link
https://originaltrilogy.com/post/id/121361/action/topic#121361

Mainly 'cause we are kinda busy, and that question isn't even 24hrs old yet. ;^P

All NTSC letterbox (non anamorphic) suffers a little from jaggies on lines that are just off the horizontal - it is purely a function of the reduced resolution available, however they are nowhere near as bad as the pictures posted here.
There is little difference between the faces and definitives in this regard, though the faces are *slightly* better.
The pics that were posted here of Leia in the war room had excessive sharpening, and a low dynamic range which made the problem look much worse than it actually is.
On the PAL set you get less jaggies in general because of the extra resolution, and the tighter framing i.e. it is 'zoomed in' more, so you lose some picture, (pan and scan 'lite') but what is on screen is bigger, so more scanlines to go around.
Short answer - they look good on our transfer - I'll do some pics over the weekend to show what I mean.

Help Wanted: a bitmap of the original green 'Lucasfilm Limited' logo?

It is extreme kerning on that too now that I look at it.
Damnit, this is going to bug me now.
Normally I'd start from scratch in Illustrator, and just trace the bitmap, my guess is that they created the typeface for the company.

I doubt that Rice did it, as I'm pretty sure that was only the STAR WARS type (which was a new typeface based on Helvetica as George wanted a "facist" typeface for the opening credits)

Both sets have their problems.
The definitive is CAV, which means there is less video noise (The SNR is up to 3DB better than the CLV version), typically less crosstalk, and better image stability, and better colour stability. It also allows you to do slowmo and still frames if you are using almost any laserdisc player.
The NTSC transfer itself has some problems, split sabres on some frames, some edge jaggies on others and some 'trails' as a result of a 'virtual' dirt removing algorithm that didn't work so great.
Being CAV it is more discs, so more side changes to deal with, and some DEF editions had some missing footage.

The US faces set is CLV, so a little more video noise, image stability- especially edge stability is noticably worse (but can be fixed with an external TBC in most cases) and crosstalk is evident on most players.
It is a better transfer in some respects, no split sabres, better edges in some scenes, none of the dodgy trails, but introduces some artifacts of its own, e.g. beter colour in a lot ofd scenes, but worse colour stability and a noisier chroma signal. Being CLV there are less side changes to worry about.

The Japanese Faces set however seems to be the same transfer as the US definitive set (albeit with a different black level) as it also has the split sabre problems.

Some of the above issues may or may not be visible depending on the quality of the player you have.

The DEF edition also supposedly is more susceptible to rot, but both my DEF sets are rot free.
This is not the only differences by a long shot- but the ones that I care about at the moment.
That is why we are using both sets to create our master.

Very much look forward to receiving any code you're willing to share, I'm curious to see what the starfield cleanup code does to the PAL LD footage and how it copes when they're moving instead of (supposed to be) static.

The 2am ideas thing, yeah I know about that one, I think it was a late night years ago when I was trying to code autosterograms from scratch (nobody would share their code online) that I figured out that one line of code that did the trick to making my own 'magic eye' pictures.


I'm glad I'm not the only idiot that spent his time reverse engineering the whole Magic eye thing, I even went as far to work out an animated version of it that nearly sent me blind. For a while there I couldn't look at any repeating pattern without it flipping into 3D, security doors, grills, wallpaper.. I had to stop 'freeviewing' for a while.

Thanks for all the links guys, but the forum owners probably don't want us filling the forum with 'free ads' for ebay auctions, so it might be best to PM or e-mail them.

We had a play with the starfield recovery on the PAL discs, it did noticably beef up the star count, but not as drastically - which is to be expected as less were 'missing' to start with.
Re the 'movement' I do a tracking pass in shake so that you don't just end up with that sort of problem.
