So what... is FLUT?

And nearly two now.... How time flies.

Graeme, our daughter is the same age and maybe you and I will be able to compare footage we shot of them on Red years from now. The footage I shot when she first started walking probably won't even look the same now because you went and made it look all better. Darn you man, messing with family memories like that. Got to love RAW!

I don't shoot enough movies of my kids. I do have numerous R3Ds of family members holding test charts for me though...

The good news is with the new sensor, Ava won't have to say "too bright daddy..too bright". I'll use a smaller, less powerful on camera light.

Seriously though, it's amazing to be capturing some of these moments with this amount of quality. Hopefully at some point when everything calms down a bit (not sure that ever happens at RED) you get a chance to take some time and get some great footage to add to the family album.

ROFL... that will translate into a very awkward sitting down with the wife to watch the home movies.

Then again it will bring you right back right to the thick of the battle, even all the way in the future when you are done squeezing all that can be theoretically squeezed out of the 617 sensor area... and moving on to the next?!

I would also add that one of the major advancements in the proposal is that the proposed file format to contain the ACES representation is based on a subset of Open EXR, basically a floating point format. This eliminates many of the limitations in precision inherent in 10 bit, 12 bit, and even 16 bit file formats.

Exactly why we are transcoding only for editorial and then re-conforming camera source in grading systems that take the output of the SDK (16 bit unsigned) and apply color transforms in 32 bit floating point space.

This level of precision is a major attraction for me, in part, because it lengthens the useful lifespan of the standard before revision is required which extends the compatibility window.

The only issue with the IIF I see is that 32 bit floating point uncompressed is going to be massive at DCI (4k) resolutions. OpenEXR supports a number of useful compression types, however decompressing the files puts an enormous load on the CPU (akin to decoding the R3D files on the CPU if not far worse). Anyone who's worked with any significant quantity of OpenEXR data in post (even at 2k) can tell you the storage requirements are massive. I did a film a while back where our pipeline was exr and we had 80TB of storage online for post (and used it).

One of the advantages of working directly with low bandwidth camera source is that the IO requirements are significantly reduced. With decoding now possible on the GPU via technologies like CUDA the need for specialized hardware may soon disappear.

Another important consideration is that new and improved algorithms are coming out of camera vendors for decoding the sensor data into coherent images on a fairly regular basis (ala redcode and the 'color science' which is soon to be v3).

With that in mind you may not want to transcode for anything other than editorial until as late in your post cycle as possible, it's a very real possibility that an improved 'color science' will emerge before you do your final grade.

Food for thought.

FLUT is the brainchild of Graeme.

The "F" in FLUT stands for "floating point".

If you haven't clipped RAW, you haven't clipped any ISO. Move your mid grey anywhere you want without fear of clipping.

FLUT includes another new color science. That's right. Number 3. Better than number 2, which was better than the original.

FLUT includes a new color space- REDcolor (more accurate than before)

FLUT includes a new gamma- REDgamma (more info from RAW than before)

Since an r3d is RAW, you can re-grade any old footage with the new color science.

FLUT works with the Mysterium sensor. It works better with Mysterium-X sensor.

Examples will be shown at RED Day. You'll be impressed, I'm quite sure.

Jim, if F is for Floating point, what about LUT?

Edit: found answer thanks!

Roberto, 4 is the right answer. And it's my 2nd daughter's first steps I got on RED. I don't have any sons. See First Steps In 4k.

This is so cool.. Can't fake that..
