I honestly don't know. I'm unaware of Dolby doing any work in video or video noise reduction. Do you know of something that they are working on? Doug

As far as I know Dolby is not involved in the video end of DVD or HDM at all. What made you think that they were? Doug

Well again don't get me wrong, I'm all for lossless audio and surely it can be an improvement on lossy audio particularly when its fairly low bitrate. The point I was trying to make though is that the techniques used to make a film soundtrack are looked down on fairly strongly by those that...

Part of the reason that the difference is not as obvious on movie soundtracks is just the very nature of the way a movie is recorded and mixed. Movie soundtracks are mixed for effect, not fidelity. Dynamic compression is used liberally. Tracks are sped up, slowed down and manipulated in any...

I can't speak for Sam, but for myself it's not your support of lossless audio that is a problem, it's your constant drum beat that is tiresome. You've taken a thread that was about DNR for video and turned it into yet another debate about lossless audio. You are getting to be a one hit wonder...

I think the resolution, 1080, is probably good enough for home viewing in most situations (unless you are getting beyond a 10 foot screen), but I agree that a 4:4:4 color space would give a better chance of avoiding color banding. But honestly I think the images that we see from Blu-ray and HD...

I agree there is way too much temptation to "play" with the images, both with color and noise reduction. Frankly I'm getting pretty tired of films that have a "color wash" over whole scenes or in some cases the whole movie. There are parts of say Lord of the Rings where they seem to have almost...

Grain free movies will be the result of more and more films being shot digitally. Personally I would and have added grain to digitally produced images. I've even go so far as to add very fine specs of dirt to give it that vintage look (the project was supposed to be a film that was made in the...

Yes that is one solution to a potential telecine problem. And again I'm not an expert telecine operator. I only know what has happened when I supervised the transfer of some films that I was the DP on. I'm not at all saying that DNR isn't being abused. I am saying that to dismiss it as a useful...

Gary don't get me wrong. I'm not saying that every single shot will need some kind of patch work. It really doesn't happen all that often. But when it doesn't these are some tools that can help the situation. And I never said that DNR didn't remove SOME high frequency, but when you have a...

I thought I was already pretty specific. First of all I haven't been talking about compression at all. I'm talking strictly about the film transfer process. Grading is simply color and density correction. There are times in the telecine process even on the best of equipment, and its actually...

Quite true. What you see in the theater is almost never even close to the potential that 35mm film has which is something in excess of 4k. What is seen at your local multi-plex is probably closer to 2k or less as it is several generations away from the original camera negative. However even at...

Quite possibly. Don't get me wrong I'm not a fan of processing for processing sake. Just when it's needed to fix problems that crop up in the process of going from a chemical medium to an electronic one. Doug

You are correct that it's not what most people would call DNR, but it is a method of altering the original image so that the image doesn't create problems in the in the destination format, just as DNR is. Again its just another tool in the toolbox that allows for a high quality presentation...

Yeah David I'm not talking about attempts to remove grain, only to tame it when it creates strange effects that were not intended. It doesn't really matter at what point in the process DNR is applied, it is applied to almost every film made in some way or another and not necessarily in every...

Yes DNR can reduce sharpness to some extent, but not necessarily across the entire frame like a de sharp filter would which would be the other and rather drastic option. Yes EE could be described a creating fake sharpness, but that only talking about when EE applied with a trowel rather than...

Man is on the right track here. The whole process of transferring film to video is not a "natural" process. Film wasn't designed to be seen on a system that has scan lines where information can slip between those lines. Even when you have thousands of scan lines, very small details, like...

I absolutely agree with this David. These tools should be used to try and make the images look as close to the original as possible with out exaggerating anything. Properly used they should be invisible. I will disagree with your added note. EE is also a very valuable tool and often images on...

The raw video of a transfered film doesn't look much like it does in the theater. Of course color and contrast have to be tweaked quite a bit to get it too look right because film has a much wider range from light to dark than video does, and can represent FAR more colors than even HD can. But...

Sorry Garry to say that Sony is using zero EE or DNR on their releases is to completely miss understand the process of transferring film to video. Some DNR and EE are used on virtually every film that is put on to video. It's just not over used. Doug

I think thats an over simplification of the situation. There are times when film transfered to video doesn't look like it does when projected. DNR and EE are excellent tools and are sometimes necessary to get the video representation of the film to look like it does when projected on a screen...

I acutally had a few projects that I shot digitally, where I added specs of dirt and dust (very subtlety, if you didn't know to look for it you probably wouldn't see it) to give people the subconscious idea that they were looking at film and not video. Doug

You are correct. I was talking more about the future with high speed film recorders. I understand that they are getting pretty fast, but no where near as fast as making prints the traditional way. Of course by the time they get the film recorders working that fast, it will be a moot point as...

Yes....and apparently 8K is on the way, both for the DI and there are 8K cameras in development. Doug

Yes David and of course today with most films using digital color timing, the DI becomes the source of all future copies of the film, be they on film or in some digital form. The interpositive and internegative will become a thing of the past as all prints are made from the DI via a film...

Yes but once a DI is made, all the color timing information is included in it and the camera negative is never touched again. And in theory the DI will never be damaged, scratched or fade, so there should never be a need to go back to the camera negative, unless there is some idea that more...

I'm not sure that the camera negative is used very often. Rather the internegative is used that has all of the color timing information from the interpositive. Once the answer print is approved the camera negative is generally stored away literally in a salt mine. The only time the camera...

Also color negative film has an orange contrast mask over it, which is why when you hold a negative up to the light, it looks orange. The orange mask is compensated for when the positive is printed. Doug

Generally the answer print is regarded as the final approved version. Although many directors are involved in the the telecine and do things differently there than they did with the answer print. So in that case both versions are correct. But if we are talking about an older film, even if the...

Well and again this brings up the question, did they really reduce the grain for the HD DVD, or is the grain just less obvious when its not on a 40 foot screen? Doug
