But with the latest news out of Marlboro, Molinari & Company have given Joe Everyman a system which includes the advantages of uncompressed -- i.e., the "lossless" image -- without paying the harddrive premium which comes with uncompressed. Even in the new world where drives sell for 20% of what they did just a few years ago, uncompressed is still a luxury that is in keeping with the 15% at the top of the market. While this segment is an ancillary part of Media 100's business, many users have long suspected that it is not the focus of the Media 100 Vision. Me, I think that it's a telling thing that Media 100 bought Digital Origin, Wired and Terran a few years back. They bought mass-market competitors, not their cocktail party upper market competitors. And this has angered many who do not seem to relate to what drives the Marlboro Man and his company of heretics and renegades.
Uncompressed, Lossless and Lossy:
As Philip Hodgetts (right, creator of the Media 100 Companion) points out in some of his own remarks at Creative Cow and elsewhere: "Once again, in terms of the codec there is no difference between uncompressed and lossless. Stuffit and other compression systems have long proved that. When I send an 8mb TIFF image to my printer in Australia for a brochure and I compress it to just over 2.5mbs, when it's uncompressed I expect the full 8mbs -- not the 2.5 it was compressed to for the sake of transferring it across the Net. Lossless is just analog to digital conversion with the redundancy taken out. Look at the Stuffit-type engine -- what comes out is what goes in. That is lossless compression and that is what Media 100 uses."
But Philip has also pointed out another interesting fact: the ability using the Media 100 scheme to seamlessly integrate legacy data from past "lossy" Media 100 projects into the same timeline with the new "lossless" footage. That's a big plus to many users. Another key facet is that this also allows access to legacy renders.
Once again, Our Affable Aussie, cuts through the crap to the heart of the matter...
Bigger Doesn't Always Mean Better:
Borrowing from one of Philip's points that he expressed elsewhere, I'd like to ask: What is going to look better, an image compressed with a lossless algorithm or an image that is uncompressed? Right. They are both the same.
Back in 1994, I remember that there was always an argument somewhere online -- usually between people on Digvid-L, Vidpro-L, the WWUG and the Media 100 and the Avid lists -- arguing about file size and picture. Back then the Media 100 algorithm was unrivaled for picture quality and yet it made smaller files. At the time, Radius, for example, made far bigger file sizes and yet Media 100 had the better image at the time. Size isn't always the answer.
As I pointed out in one of my own recent posts: "Media 100's picture was far greater back then and even at 60 and 80kb (the limit back then) people were getting projects snuck onto the air. I remember more than a few Media 100 Nubus systems that were quietly churning out broadcast material and most of the producers wouldn't let you know they were using them for fear they'd shoot the goose that was laying the golden eggs.
Point Number One: Even with much more compressed files, the Media 100 looked far, far better than files which were much less compressed. It was the quality of the compression algorithm that made the difference. It still does.
Point Number Two: It is quite possible to write algorithms that can track all of an image's data and yet compress the data significantly. When these images uncompress and the image contains 100% of the picture information, what do you call this? Right. Lossless compression."
As Philip and other users have pointed out, Stuffit and other compression tools have long proven that you can compress a file and not lose data. Look at it this way: When was the last time that you compressed a data file and opened it only to find that in order to get it compressed, Stuffit threw out the first 5 pages and the last chapter of your report??? It just doesn't happen that way. You compress it and you get your report. All the letters and the formating are there.
A Simple Description of Lossless Technology:
A great example of how it can work is thinking about a "talking head" shot against a bluescreen. Yes, you can bring it in totally uncompressed and have a huge file where all frames are exactly the same size no matter the frame composition. Or, you can use a "lossless" algorithm that is "smart" enough to see that there is a lot of blue that never changes -- so track that as a single value that let's say for example sake is 100,000 pixels. The algorithm would basically say that all the pixels between 1 and 100,000 are all blue. So that could be compressed as a mathmatic formula that tracks all non-moving blue to one value instead of tracking all pixels individually.
Then only the "moving" blue pixels would have to be "watched" as individual pixels -- you know the ones which are adjacent to the talking head and so their values are fluctuating as they blend with the hair and skin tones of the talking head as it moves through the field of blue pixels.
Using this formula, you can do a lot of compressing and still be "lossless" while still giving yourself the luxury of not having to bury yourself in drive space. (Theoretically, though often depending on the subject matter, you will have to bury yourself as if the subject matter includes a lot of movement -- say like shooting a lot of water rippling with sunlight sparkles on it -- you will be eating full frame a lot of the time.)
Is this the perfect solution for everyone? I doubt it. There are those who for multiple reasons, need the "marketing edge" that comes with the words "Uncompressed Images." But in the world of nonlinear editing, don't kid yourself: A lossless image and an uncompressed image are virtually identical -- sometimes absolutely identical.
But as to the cost of the upgrade to get there, that's your call and that's up to you to decide...
