Happy New Year everyone

Raylight MXFX is for sale now, for Windows platform. One of the
more interesting features is you can do a noise reduction pass
as you are copying the P2 Cards to your hard drive. Noise levels
are typically reduced about 50%, so in principle you could shoot
at +6dB gain with no added noise, or choose normal gain levels
with a smoother look.

There is a free demo version at http://dvfilm.com/MXFX
 
And the Macintosh version will also have this functionality reasonably soon?

Congratulations. After doing product reviews and working with developers for nearly fifteen years,
I have say that your dedication to providing additional functionality is among the best I've experienced.

Yes pretty soon, within a month I think.

Can you post some examples of the noise reducttion - especially with blocky noise?

Thanks!

Yes, here is a 2-layer photoshop file, the top layer with noise reduction and the bottom without.

Best viewed at 200%. The effect you should see is less noise on smooth
flat areas but retention of sharpness around highlights like the reflections
in the eyes.
 
ok let me understand this, lets say we shoot with the hvx with no added gain, it will still remove noise created by the camera even if we shoot it as clean as posible?
 
What about moving footage? Does this create a "blur" effect because of the de-noising process?

no, it senses motion and does not blur over time where there is motion. It also does not blur over space near edges so you don't get an "out-of-focus" look

In other words the temporal blending (blending over time) occurs in static areas of the screen, which can have detail as long as they're not moving. And the spatial blending (blending of surrounding pixels together) occurs in flat areas of the screen where grain is most visible, but not in detailed areas. The only places where you don't get any benefit are in detailed areas that are moving around, however the eye is not fast enough to see grain there anyway.
 
Don't mean to be a pain... but any chance of a comparison of moving footage? I'd particularly love to see a scene of the type where rthe HVX tends to have excessive blocky noise - a scene with a a dim gray wall, a dark background, etc...?

Thanks!

There is a free demo on the webpage, give it a try
 
I am using Raylight to convert MXF files to Raylight avi files and using Vegas as my editor. Using P2 Maker I create new MXF files. Can I then use the new MXFX to remove noise that I caused during any color correction or other effects I might have used in Vegas.
