Red Giant BulletProof

LUT

BulletProof loads and saves LUTs as 3D 32x32x32 .cube files. Using a LUT can help clients and directors visualize how the final clip will look. A LUT will treat your footage as a reflection of the final output, whether it's straightforward corrections or more creative stylized looks.

What is a LUT? A LUT or “Look Up Table” is a file with multiple color corrections embedded within it. This file is typically generated by your editor or colorist, with settings to simulate the final color treatment. The LUT applies a complex — but simply executed — transform from one gamma interpretation or RGB color space to another.

Already know Red Giant? If you are familiar with our free Red Giant LUT Buddy product, then you already know how to this LUT tool. The only difference is that BulletProof's LUT tool uses GPU processing, while LUT Buddy doesn't.

 

 

Load a LUT preset

BulletProof ships with preconfigured LUTs to help adjust your footage in certain lighting conditions. To use a LUT preset, click the Applied menu and select the preset name.

LUT presets are installed with BulletProof, and the LUT tool will initially browse to that location, which is: User/ Library/ Application Support/ Red Giant/ LUTs.

The supplied LUTs are primarily for common Canon workflows.

  • CineStyle is Technicolor's LOG-like picture style for Canon DSLRs. Our LUTs were created with use of the CineStyle LUTs or Color Assist.
  • EOS Standard is based on using the EOS Standard setting, which is the default in the Canon camera. These presets take into account the EOS look, which already has a lot of contrast and saturation.
  • Prolost Flat turns down the in-camera setting for contrast, saturation and sharpness.
  • Each of the Prolost Flat and CineStyle settings uses a custom contrast curve and saturation adjustment to closely match the EOS Standard output. The variations add a warm or cool temperature shift on top of the curve and saturation, a la the Warm/Cool tool in our Magic Bullet Looks product.
  • The Mojo adjustments add a bit of Color and Punch — technology from our Red Giant Mojo tool — to the images on top of the curves and saturation adjustment.

 

 

 

Load a LUT file

To load a LUT file of your own, click the Applied menu and select the Choose... option. Then browse for your LUT file and select it. The name of the LUT gets checkmarked, and shows in the Applied menu.

By default, None is selected, so no LUT is accidentally applied to your footage.

BulletProof can load one LUT at a time. You can import any LUT into BulletProof that has been exported as a .cube file. BulletProof won’t support a LUT that has diffusion or blur.

 

 

 

Export a LUT file

Creating a LUT file is as easy as loading one. Go to the Color Preset menu, and choose Export Color Settings as LUT. The Save a LUT dialog box will open so you can name and save the 3D .cube file.

You can also access this menu item by context-clicking anywhere in the Color Settings panel.

All settings in the Color Settings panel will be saved in your LUT file, including any settings loaded from an active LUT. For instance, if you made adjustments in Colorista 3-Way and Curves, and loaded the "ProLost_Flat_to_cool" LUT preset, all of that color information will be saved to your new LUT file.

 

 

 

Why use a LUT?

There are many reasons to use LUTs in BulletProof.

Confidence on set. A LUT is great for accurately generating proxy files. If there are problems with footage while on set, you can reshoot immediately, avoiding the cost and hassle of coming back later.

Quick creative styles. LUTs can also be generated for creative treatments of media. Some LUTs can provide common gamma adjustments, while others may deepen shadows, add contrast or correct low exposure.

Talk to other color systems. Use the LUT tool to communicate with higher end systems ranging from DaVinci Resolve to Panasonic displays. If you’re already using 1D or 3D LUT’s in your workflow, this tool was designed for you to share values between compliant software and devices.

Use for a final color master. Occasionally you may bake a LUT into a final color master. This kind of color treatment is useful for a quick turnaround, if you care about just grading it as a first color pass, and you're worried about making the color treatment perfect.
