Step 3 
Select your captured frame, then click Develop to work on it. Here’s where the magic happens: You can change white balance, add contrast or vibrance, go black-and-white, or even adjust curves. Work your still the way you’d work any other RAW file. (Not all of the tools work. Because video is a time-based medium, you can’t make adjustments such as noise reduction or spot removal that would affect images differently from frame to frame.) Head over to the Presets panel and click the plus sign (circled) to create a preset for your video. It’s okay to leave most of the boxes checked—Lightroom will apply only what is possible when you use the preset.
