Classic Cartoons Marred by Digital Restoration

Carl Bialik from the WSJ writes "When classic animated films undergo digital restoration, key features can get lost in translation. The Wall Street Journal reports that the process meant to smooth over scratches and dirt specks on old film "can also remove some of the lines that make up the animation -- for example, blurring Tom's face in a Tom and Jerry cartoon, or erasing lines in Woody Woodpecker's fast-moving beak." "

    It does not look like the orignals had any scratches or dust (from the examples). Of course it is going to be harmful (don't fix what ain't broke). Anyone have any example of poor/dusty film that this might help with?

    Why are they complaining about the tools when it's apparent that it's the workmanship that's at fault?

    For an excellent counter example, check out the beautiful work that Animeigo did restoring the original Macross series when they released it on DVD a few years ago. The cleaned up print makes the series look like it was ten years newer.

      for release on televisions, 1080 line HD is considered by the industry to be high enough quality. at this point, anything bigger than that [2k or 4k, for instance] i used only for material going back out to film, or for insanely high-budget work. it's rapidly moving towards 2k and 4k, but for now, they're still primarily used for digital intermediates, where the target medium is film.

      Actually, in older film stock its not, and thats why we have the whole noise reduction process... to eliminate the "grain" caused by the crystals in the film being noticably large.

      The point of NR is not to eliminate grain at all - in fact, grain is part of the image, and ideally is not removed or damaged when doing noise reduction. NR was designed for the removal of *noise* in a video image. as in, random noise on analog tapes. used properly [and lightly], a DVNR unit is an invaluable tool in DVD production. unfortunately, it's usually not used properly. ...and it has the unfortunate side effect of decimating the grain structure of the original film.

      My company offers digital restoration services for feature films. We recently completed the restoration of the animated film "Rock & Rule," which is due out on DVD in a couple weeks. this was a restoration done by hand on an MTI CORRECT system, which allows you to manually correct each frame. It does automate some processes, and some of the cleanup is done by pulling data from surrounding frames, which has the effect of erasing defects while leaving the grain structure intact [at least, perceptually - you are actually changing the grain a little].

      But again, done right this means someone has to be sitting at the machine looking at every frame. It took our restoration artist a full month - about 180 hours - to go through all 112,000 frames of that film, and that was somewhat of a budget job, were we were simply removing defects [deep scratches, dirt, chemical stains, splice marks] on a release print, not defects that existed in the original cells and were permanently printed into all release prints.

      We use a DigitalVision DVNR for some analog material that goes to DVD because there's more random noise in analog, and the DVNR is dangerous if not used correctly. It's a box that's designed for broadcast applications, a set-it-and-forget-it kind of deal. but we've found that it's most useful when used sparingly, and only on select scenes rather than the whole movie. I mean, just take a look at most digital cable or satellite broadcasts to see heavy noise reduction artifacting.

      the tools are not perfect, and it's going to be a long time before they are. So lots of manual work is involved in this kind of restoration, at least for the forseeable future...

    I gotta agree with you there kickabear. This is the same argument that people make for not touching up old music. The old analog recordings gave older music a tone, warth, and quality that a lot of nodern digital recordings don't have. A lot of musicians still love the old tube amplifiers for the same reason.

  10. Re:Poor quality control by badasscat · · Score: 2, Interesting

    Although I'm not surprised, I'm disappointed that this isn't part of the standard process. To me, just running the film through DNR is lazy and indicative of a company just trying to make a quick buck. If you want to use a DNR machine, you gotta get a real person to check the work. Period.

    I agree, but Disney's talking about manually correcting every single frame and for a 2 hour film you're talking more than 175,000 individual images. That is a huge number of man-hours, and frankly, there's really no need for it.

    There's nothing inherently bad about DNR systems. They're a tool, and like any tool they can be used for good or evil. The problems come in when you start asking them to do things that they're not very good at doing - like removing hairs or specks of dust. These objects are not "noise" - which is what "noise reduction" is supposed to get rid of - these are things that do need to be manually removed by somebody that knows that a drawn line and a hair are not the same thing. A computer is not going to make the distinction reliably.

    I think ideally what you want to do is light digital noise reduction to reduce noise, and then further manual correction of individual frames that need it (or really, the other way around). There's no reason to manually go through 175,000 frames, though - there should really only be maybe 1,000 or so that would need manual attention on any given film. That's a cost-effective way of ensuring high quality without breaking either the budget or the schedule.

    Unfortunately, a lot of studios apparently don't even go that far; they just rely on the computers to do everything. There are still QC monitors at the end of the process, but when all is said and done do you think their complaints that "the picture looks a little fuzzy" are going to be met with anything other than "there's no noise, there's no hairs, ship it out!"?

    I'm surprised no-one has mentioned the level of digital vandalism all forms of moving image have been subjected to in the name of "restoration".

    I mean, there's plenty of jokes about Greedo and Han Solo but no-one has mentioned anything about starfields.

    When the remastered Star Wars trilogy came out, I was appalled by the hatchet job they'd performed. In any of the outer space scenes, when the camera panned, the stars changed size. It convinced me that digital remastering was worthless.

    However, a few years later I did a module on Computer Graphics at uni and I worked out that the problem was simply that they use point sampling. (I'd already had a vague notion of what must be happening, but couldn't put it into words.)

    Throughout the computer world, we use anti-aliasing to try to avoid such size issues and to get rid of jaggy lines; chemical film anti-aliased itself due to its natural area-sampling behaviour; surely it's only natural that when these two worlds meet, we anti-alias our video?

    Seemingly not. Even today, "Definition" and "Clarity" are the goals or the digital remasterer (remastermaster?) against all past experience. I recently bought an Italian film on DVD. It had such beautiful scenery -- the cliffs and rock-pools of the Sicilian coast, the clear blue skies and the bone-white stone walls of the houses and fields. The complex motion of the waves on the surface, the shape of the rocks on the bottom and the eratic patterns of light were translated into seemingly random noise if the camera panned slowly across them. Hit the pause button, though, and the picture leapt out from the screen.

    I think that's the problem -- the people making decisions on the technology have probably been given stills to compare; so the commercial products would have been designed to produce stunning stills that can be used to sell their products to the production companies, and video would have become a secondary consideration to the developers.
