F55: F5/F7/F55 CineEI LUT primer, quick quide & history

Piotr, I don't use Vegas at all. I only suggested that you look into the workflow because I knew of how well it had supported Sony log footage even all the way back to the slog1 / Sony F3 days. Back then and even in recent versions of Davinci Resolve there was no IDT for the original slog1 so Sony Vegas was a bit of a hidden gem.

I'm a hardcore Davinci Resolve user so don't get me wrong, but if you wanted to stick to a pure Sony Vegas workflow I don't see why you would need Davinci Resolve at all. You can get 3rd party LUTs that work on already de-logged images (REC709 LUTs) and they will work pretty good so long as your base footage is exposed good and your base white balance is set. In reality you don't need to use LUTs at all unless you are really digging someone's third party LUT they've developed. Most simple looks can be made with basic tools but or more advanced colouring functions like power windows, qualifiers, etc.. nothing is a time saver like Resolve.

Yes another option which a friend of mine uses to get more "film stock" looks within Vegas is the film convert plugin. Download the trial and give that a try. You can use the looks on REC709 footage or it supports slog2/3. Yet another way to get some looks on your footage. :)

For your 10-bit monitor, are you using something like a BMD decklink mini monitor to get true 10-bit color from your computer? I've been told by the guys on a colouring forum that if you don't use a 10-bit card to your 10-bit monitor you are not getting 10-bit color. On Mac only recently did the OS start supporting 10-bit color but supposedly even that's not enough… you need a 10-bit card.
 
Hi Piotr,

I probably sounded a bit glib about the 'grade till happy'! That's assuming that your monitoring has been setup and calibrated to a point where you are happy that you have a Rec709 reference.

I was just trying to give an explanation of why you would see a 'doubling up' effect if you apply a Rec709 LUT to footage you have already graded to look good on a Rec709 (or quite possibly sRGB) monitor. If you make corrections and are intending to use a log to Rec709 LUT, make sure that it is in place whilst you make your corrections.

Other people would be able to give you a much better idea of specific software workflows and round-trips - I'm just a cameraman with an unhealthy interest in the maths side of it all ;-) ,

No, that isn't true; high-end nVidia cards can be "forced" to work in up to 12 bit color mode - here is an excerpt from the M4000 Quadro:

ADVANCED DISPLAY FEATURES• Support for any combination of four connected displays• Dual DisplayPort 1.2 (supporting resolutions such as 4096x2160 @60 Hz)• Dual-link DVI-I/DVI-D outputs (up to 2560 x1600 @ 60 Hz and1920x1200 @ 120 Hz)• Internal 400 MHz DAC DVI-I output (analog display up to2048x1536 @ 85 Hz)• DisplayPort to VGA, DisplayPort to DVI (single-link and dual-link) and DisplayPortto HDMI cables (resolution support based on dongle specifications)• HDCP support over DisplayPort, DVI and HDMI connectors• 12-bit internal display pipeline (hardware support for 12 on supported panels,applications and connection).

PS The beauty of my solution is that with a simple Displayport->HDMI dongle and straight to my UHDTV HDMI 2.0 port, I'm not even entering the world of professional and expensive SDI cards/monitors...

Perhaps those guys are saying to use a decklink mini because most of the pro colorists use Flanders or lower budget Eizo monitors which sport 10-bit HD-SDI inputs.

That M4000 sounds interesting but it looks pricey at about 3 times the cost of a GTX card with the same performance, whereas a deckling mini is $137 USD - but is strictly SDI.

From getting educated on the colorist forms, really and truly what makes a grading monitor a grading monitor is the lower levels of black it can display. Dreamcolors, Ultrasharps and any expensive gaming/cad/photo-enthusiast monitors are "nice" but don't have the capability of display the lowest black levels needed for professional grading. Aside from that as you know there is the method to which it's calibration is conducted and if the monitor can use 3D LUT again for purposes of calibration.

I've been racking my head researching and trying to find a "cheap" grading monitor but in the end realize there is no such thing. You either get a real grading monitor or you don't. There's really no in-between.

Guess I'm saving up for that next… :shocked:

My thoughts exactly, Dennis - plus my SUHD TV can double as - well... a TV :)
Oh, and I quoted specs of M4000 as those I found in the net; in fact I have a much cheaper K2200...
