Info: GOUT Anti-aliasing

I'd given up on those jaggies. I'm just going to stick to the improvement offered by a simple EEDI2().

I also tried DeGrainMedian in conjunction with MVDegrain2. It performed slightly better at removing grain but unfortunately removed detail out of motion/panning scenes (which are already in poor shape after being trashed by the '90s DVNR algorithms).

Yeah, those jaggies are probably well beyond any attempt at automatic fixing. In any case, if you're going to use EEDI2, I'd strongly recommend you in the way I mentioned earlier:

EEDI2().TurnRight().EEDI2().TurnLeft()


It stands to reason that the above line should help in most cases as it processes along both the horizontal and vertical axis, therefore jagged lines that are too steep for the first part should be easily handled by the second one.

I agree, that doesn't even look like a line anymore. You might want to try NNEDI (the recently released successor to EEDI2), but I doubt it will do much good.

EEDI2().TurnRight().EEDI2().TurnLeft() is indeed one of the best antialiasing filters on the Avisynth side. For extreme cases, preceding it with AAA() (it's an avisynth function, you need AAA.avs, UnFilter.dll and SangNom.dll) produces awesome results, but the problem with AAA() is that it blurs the picture too much.

Moth3r, good call using MVDeGrain2, it's an awesome denoiser. By the way, you can increase its effectiveness if you feed its MVAnalyse portion a denoised input in this manner:

source=last
denoised=YOUR_DENOISER
backward_vec2 = MVAnalyse(denoised,isb = true, delta = 2, pel = 2, overlap=4, sharp=1, idx = 1)
backward_vec1 = MVAnalyse(denoised,isb = true, delta = 1, pel = 2, overlap=4, sharp=1, idx = 1)
forward_vec1 = MVAnalyse(denoised,isb = false, delta = 1, pel = 2, overlap=4, sharp=1, idx = 1)
forward_vec2 = MVAnalyse(denoised,isb = false, delta = 2, pel = 2, overlap=4, sharp=1, idx = 1)
MVDegrain2(source,backward_vec1,forward_vec1,backward_vec2,forward_vec2,thSAD=400,idx=2)

(my preferred denoiser is DeGrainMedian FWIW)

I never heard of horizontal aliasing though, are you sure it's not dotcrawl?

.: The XØ Project - Laserdisc on Steroids :. (SEE FIRST POST FOR UPDATES) (* unfinished project *)
Time
If I understood correctly, releases will include native resolution and upscaled versions. Also, Laserdisc video is analogue format and so doesn't have an actual resolution to speak of, right? Still, given that TV and VHS captures are done at 768x576/640x480, there should be plenty of image detail to start with. Also, playback of a resampled file will always look better than upscaling since current interpolation filters are MUCH better than the (at best) bicubic we are accustomed too. Take a look at the following page in order to see the best interpolators in action:

http://www.general-cathexis.com/interpolation.html

Most of them don't look too good, but bear in mind all of them represent a 4x enlargement, which for a 720x480 video would mean a 2880x1920 result. A 1920x1080 result, which would represent a ~2.45x enlargement, might be able to get to look very nice if one of the better, feasible-for-realtime methods in that page was used.

Feedback Wanted: Calling all people with good hearing and some knowledge in audio editing/restoration
Time

I am about to start restoring the “Making of Gabriel Knight” movie that came as a hidden extra with the CD-Rom versionwith an old game I own. The audio on it is, as expected, awful: 11025Hz, mono, and 8bit. I intend to make it a 48000Hz stereo 16bit file, with some enhancement in between the processing. This is where I need your feedback. What I first need you to do is tell me which difference (if any) you find between these two files:

http://www.bestsharing.com/files/ITw3NaJ262924/1.flac.html
http://www.bestsharing.com/files/lOC0zZq262901/2.flac.html

After that, I’d like to hear your suggestions on how to improve their quality. Any and all feedback is welcome and extremely appreciated.

23.976 FPS to 25 FPS pulldown

Yes, you can and it should play without an issue. The easiest way to do it is using DGPulldown. Select "Custom", enter 23.976 --> 25, leave the rest of the options at default values and just click on "Convert".

and the Epoch Gamebox Penta:

I've been looking for them for many years and never found any place or auction site that sells them. If anyone can help me find these two great pieces of my childhood I'll be very grateful .

Is it safe to modify a capture card?
Time
I am probably going to uy a capture card (Compro Videomate X800) soon. Since one of the uses it will have is capturing laserdiscs and this card doesn't have BNC connector, it would have to be put in.
I was wondering if the required modification could result in an increase of interference and/or otherwise potentially harm the image quality of the captured video. If so, I'd like to know how much image quality would I lose using a BNC-to-RCA adapter instead.

Now if we could only find someone into doing that sort of thing...


I am in the middle of a couple of DVD projects, but once I finish those I can take this on .

fog, do you think you can upload the 640x480 versions somewhere (rapidshare et al) or e-mail them to me?

What PAL/NTSC Laserdisc players would you recommend me?
Time
Well, I live in Uruguay which is a PAL country. Then again, most DVDs here are NTSC and people can play them back without issues. So whatever few Laserdiscs are available here are probably NTSC as well. Moreover, I'm in talks with Karyudo about buying his V800 and I trust a member of this forum a lot more than a random stranger in eBay since I know people here take care of their A/V gear .

Just for argument's sake though, how would you rate the V4300D against the V800?

Info Wanted: Charlie Chaplin shorts - where can I find them?
Time
I don't think they are, and even if they were these dedicated remasters and restorations are well worth the price if you have any appreciation at all for Chaplin's work.


OgOggilby, you were definitely right about the Mutuals being much better. I downloaded "The Floorwalker" to see if it would be worth to buy the DVD and my father and I laughed a lot for most of its 24mins duration. We are definitely going to buy the whole set. Thanks a million for the recommendation http://smilies.vidahost.com/otn/wink/thumb.gif.

Time
I am in the process of trying to buy a Pioneer LD-V8000/V800 player but apparently it can only play NTSC discs. I am pretty sure that most of the (likely very few) discs available here are NTSC, but just to be sure I'd like to know if you guys could recommend me a player that can handle both PAL and NTSC and is on the same league as the V8000/V800.
