A "bit perfect" audio capture means that Every. Single. Bit. in the capture is the same as what's stored on the digital medium (in this case, the digital track on an LD).

Some older sound cards did digital post-processing (programmed in the driver) on the TOSLINK input (e.g., band-pass filtering) without notifying the user and without giving the user a way to disable it. Hell, some even did it in the hardware.

I know this sounds absurd since all the sound card needs to do is dump the PCM bytes it receives over the TOSLINK input onto the HDD, but this wasn't (and isn't) always the case. This is why some sound cards advertise "bit perfect" audio capturing.

It's not a gimmick. It's a response to the stupidly-written overzealous drivers of yesteryear.

Any news? Thanks!

I just built my new computer, so it won't be long now!

I'll get it uploaded as soon as everything is up-and-running.

I'm sorry for taking so long!

Would I be able to extract the individual frames from this....or will it blend them together thereby resulting in ghosted images and things of that nature?

Yes, assuming that the person who captures it is using a good capture card (e.g., the Blackmagic Intensity Pro), then we can assume it won't do any frame-blending or any other kind of hocus pocus.

Is it lossless on the quality aspect? (audio doesn't matter, only video)

All you need to do is to capture it uncompressed over HDMI using something to either ignore or strip HDCP.

drngr might be able to help.

Individual frames going to be preserved?

Please rephrase this question. I don't understand what you're asking here.

Given that it's streaming from a webservice, and they're the ones that compress it....

That's true. I should have explained myself better.

This method would, under ideal conditions, result in no more quality loss.

It would be, for all intents and purposes, an absurdly-large duplicate of the compressed video stored on Amazon's servers.

That's what I thought muddyknees2000 was asking for.

Wish there was a way to rip it with no quality loss.....(assuming it was decent HD)

There is. Check it out and let me know if it's worth it.

Andrea: Try g-force's script instead: http://originaltrilogy.com/forum/topic.cfm/New-colormatching-script/topic/15002/

Andrea: Colourlike doesn't make a new histogram every 1000 frames when you set every=1000. It samples the movie in 1000-frame-steps and still makes one histogram. All the every argument does is change the sample size.

My script generates a new histogram for every frame. That's the difference.

You should see results immediately with my script because it's not doing a WriteHistogram for the entire movie at one time, just the frame it's currently on.

Can someone post these frames from kk650's re-graded The Matrix to that thread?

Andrea: Which method is `ColourMatch'? It looks the best IMO.

Thank you for the response, it just sucks you can't find any real in depth info online regarding this, if you think of anything else to add please do, thanks again.

well I did find this,

http://support.creative.com/kb/ShowArticle.aspx?sid=10843

Do you have that dialog window available with the drivers/applications that were installed to support your sound card?

I'll have the featurette uploaded later today under the "Preservation Discussion" thread.

Where is that?

amps.boards.net

I only enjoy '78 and '80 BSG.

With that being said, one of the main reasons I watch the show is for Sarah Rush!

Just... wow.

:-D

JEDIT: It seems I'm not alone! http://johnnycat.wordpress.com/2011/05/20/crushin-on-sarah-rush/

I thought it was a combination photochemical/digital restoration like the Star Wars SE.

That makes more sense.

Some here think it was SleepingBeauty-level reanimated. That just doesn't make sense to me.

We need to take a closer look at the Snow White LD.

I'm still having trouble believing that it was reanimated. It makes no sense.

(It was, of course, the first film to ever be 100% remastered in a computer, but that doesn't necessarily mean that it was reanimated ala Sleeping Beauty.)

Why, after going through the whole reanimation process, would they do one of the following?

1. leave the gate-weave in
2. re-insert the gate-weave
3. print to film and then to LD

Hi,

Can someone please point me to where I can get a copy of the ESB vinyl transfer mentioned in this link?

Thanks!

It's only on Usenet (a.b.starwars) at the moment.

You might not have write-access to the directory Avisynth is running from.

Try changing "hist1.txt" and "hist2.txt" to something like "C:\<...>\hist1.txt" and "C:\<...>\hist2.txt".

Replace the "<...>" with a directory you know for certain that you can write to as the current user.

Alternatively, you can try running whatever program is executing the script as an administrator.

I followed your instruction and, despite the fact that this time the two histogram files were written (but are small, 5Kb, it's normal?) I continue to have the same error messages...

Forgive my ignorance but can chroma from an SD source really be combined with luma from an HD source without any perceivable loss in image quality?

Chroma is less "noted" by the human ey ethan luma... for example, a full HD luma resolution is 1920x1080, while chroma is 960x540 (1/4th) while VHS is 350x480 luma (NTSC) and 30x480 chroma(1/12th)!

Consider that PAL DVD has only 720x576 luma and 360x288 chroma, but when upscaled it will reach the same HD resolution, and, as chroma is less "important" (to the human eye) than chroma, the eventual artifacts given by the upscaling process will pass unnoticed.

Let's discuss this one-on-one in a web-chat sometime soon. It'll be a lot easier (and faster!) than trying to do this on the forum.

I'm just saying someone you've collaborated with on a project is going to be more noticeable when they vanish without explanation.

I'm going to guess (hope!) msycamore's just on an unannounced-extended-break from OT.com.

Google around to see if the 70SB088000004 does bit-accurate recordings via its TOSLINK input.

Unbelievably, some cards don't, even though the data itself is digital!

Go for it, Brooks! It's a good deal.

The CLD-D504 is an good mid-range model. It also has AC-3 RF output, IIRC.

If you live near VA, you might want to consider bringing it to Kurtis Bahr for calibration.

the histogram files are not written, too. Can you help me, please?

Still nothing. He hasn't been online since 19 June.

What's the difference with my script?

Yours generates a single histogram for the entire clip and then uses that.

Mine generates a new histogram for every frame.

I still use Windows XP on my desktop computer because I have a bunch of old hardware with XP-only driver availability.

With that being said, I do all of my programming on *n*x machines; e.g., OpenBSD and Linux (Debian).

I'm also on iOS all-the-time with my iPad.
