Only two weeks ago Adobe Premiere Pro CC received its latest major update (2015.3) boasting a ton of exciting, new features such as proxy media creation, VR video workflow support, additional native formats and more. Among those new enhancements is the HSL Secondary section added to the Lumetri Color panel. In essence, it allows users to isolate a color/luma key and apply a secondary color correction to video clips imported in Premiere Pro CC thus being able to create even more advanced and customized looks within their favorite NLE. Jordy Vandeput of Cinecom.net covers the new functionality of the Secondaries of the Lumetri color panel by showcasing a workflow regarding isolation of a specific color in a video clip.
You can utilize the Secondaries in three easy steps. First, you need to define the desired color (set the key), then you can refine your mask and adjust it accordingly. You can further change the color, play with the levels, sharpness and saturation by using the provided three-way color correction tools.
You can find the Secondaries at the bottom of the Lumetri Color panel under the HSL Secondary section. The Key, Refine and Correction tabs give you all the controls you will need to perform the task. First, to set a key, choose an eye-dropper, move over the color range you’d like to sample, and then left-click to apply the range. If you hold down the Cmd/Ctrl modifier key while hovering over the program monitor, you can set the eyedropper to a 5×5 pixel selection.
Furthermore, use the range selector tools to fine tune the range. Below you will find the controls that will help you to refine the isolated color just as you would normally do in Resolve, for instance. You can also exclude a certain color tint from your selection by using Remove Color.
Furthermore, you can refine the key with the Denoise and Blur controls provided within the Refine tab. Finally, in the Correction section, you can do all the desired changes you want to the isolated color by utilising either the one way or three-way color wheels. The default color wheel gets displayed in a mid-tone control. To switch to a three-way control (like the Lumetri wheels section), click the accordion button at the top. You can also invert the selection by using the following button placed at the bottom of the Key tab shown below.
If you want to take the process one step further, you can create a separate mask to eliminate the color spills in your image. To do so, duplicate the clip that you’ve already modified and then drag it on top of the original video in the timeline. Just create a mask by using the clip properties panel and do tracking if necessary. Once the tracking is completed, you can use the range selector tools in the Lumetri panel of the bottom layer to eliminate the unnecessary spills in the rest of your image just as shown in the video tutorial above.
