|DINR vs No-Noise vs Cedar?
I would have thought that DINR would have run away with the prize,
but it seems that Hollywood is more inclined towards No-Noise. Am I right?
The first, which is sometimes called "Berger's Law", is "These things work best when you need them least." This means if you have a little bit of hiss, the Cedar DH-1 is great. A lot of hiss, crank it way up, you really hear it work and the artifacts become distracting.
This leads directly to the second principle, which is . . .
I have found the Cedar system to be more an effective hiss reduction than a broadband noise reduction device.
In terms of No-Noise vs. DINR, I have found that the No-Noise, in the hands of an experienced operator, with the guidance of the dialogue mixer, can produce excellent results. At Fantasy Films, the record company uses No-Noise all day every day to clean up old jazz catalogues, and we have a very practiced engineer do our dialogue work. He comes to the stage, we play him the tracks, we go to his room, he plays us varying degrees of processing, and we get several takes. This process literally saved two performances in Robert Duvall's "Apostle," where he and Miranda Richardson are dining at a Bayoufront restaurant. Fortunately, the bayou was infested with piranhas, so with their help we were able to save the scene.
The most difficult noise to remove, of course, is noise which changes in spectral content and level over time. Classic examples in film post include car and airplane-bys under production dialog. Wind and surf are frequent offenders too.
Can't tell you what "Hollywood's favorite" digital noise reduction system is. I know that both DINR and Cedar were used on Episode One.
I've used DINR quite a bit. It saved us way back on Forrest Gump when ciccadas covered Tom Hanks' dialog at the cemetary. I've used No-Noise and Cedar less, but I know they're both good systems.
My hunch is that if you're careful and persistent with any of the three
you'll get good, if not miraculous, results. I doubt seriously that any
one of them is clearly better for all applications.
