Further adjustments to the image may be necessary to fine-tune the look. 709 standard-dynamic-range (SDR) luminance levels. 709 SDR: Choose this option to convert high-dynamic-range (HDR) clips (such as PQ, HLG, or log media that has been color corrected in HDR) to Rec. Apple’s Help files explain the four options to choose from: Select the clip you want to adjust, go to the Video Inspector and choose the setting that represents what you need to do. To apply it to a selected clip, or group of clips, double-click HDR Tools effect in the Effects Browser. To apply it to a single clip, drag it from the Effects Browser on top of the clip. Given that we still have access to the full-range of color correction tools, we can easily grade this image to look the way we want in this case, a California cliff near sunset. 709, both out-of-bound highlights and shadows are corrected. When we apply the HDR Tools effect, and set it to HDR to Rec. When we look at it in the timeline, highlights are too hot (above 100 IRE) and shadows are too dark (below 0 IRE). This HDR clip is then edited into a Rec.709 project. 2020 HLG clip, which is properly identified by FCP X in the Info Inspector, with a Panasonic V-Log LUT applied. 2020 PQ), and then create a compound clip of the entire timeline and place it in an HLG project.Ī common use for shooting HDR media is to provide more flexibility in color grading traditional HD projects that use Rec. For example, you might color correct a PQ project (a project configured for Rec. A compound clip that has been set to either PQ or HLG.A source file that is not HLG or PQ (it could be log or RAW, for example) but has a LUT applied (either a camera LUT or a custom LUT effect), where the LUT is designed to output HLG or PQ video.This could be media originating from a camera or media exported from Final Cut Pro, Motion, Compressor, or another app. MOV or MXF files that were encoded directly using the HLG (Hybrid Log-Gamma) or PQ (Perceptual Quantizer) standard.For example, you might use the HDR Tools effect on any of the following kinds of wide-gamut HDR source clips: You can use the HDR Tools effect to convert wide-gamut HDR video clips from one color space to another or to set the maximum brightness of a clip. The good news is that HDR Tools allows you to easily convert an HDR clip from one format to another. The closer they match, the easier it will be to create the final master. This means that your project settings should match the codec, frame size, frame rate, and color space of your final deliverable. Larry’s Universal Rule of editing still applies, even when creating HDR projects: Set project settings to match the media format you need to deliver. While some cameras are limited to a single color space, many cameras can shoot two: Rec. The problem is that a camera can only shoot in one color space at at time. For this article, I’ll call both PQ and HLG “color spaces.” NOTE: Technically, PQ and HLG are called “transfer functions,” but it is easier to think of them as different color spaces. 709, while HDR uses one of several different “flavors” of Rec. Ever since, I wanted to share more about this with you.Īs discussed in this article – The Basics of HDR Media Explained – different media use different color spaces. I first discovered it as I was working on my “ HDR Media in Final Cut Pro X” webinar. HDR Tools is a utility, included with the latest version of FCP X, that converts HDR media between color spaces.
