Work natively in Rec. 2100 HLG (Hybrid Log Gamma) in Premiere Pro.

HDR offers wider color and light ranges that are closer to real life. With Rec.2100 HLG color space support in Premiere Pro, broadcasters can work with more vibrant and dynamic content.

Apple ProRes and Sony XAVC Intra codecs are both fully color managed and GPU accelerated throughout the HDR pipeline in Premiere Pro. This is not just one feature; this is a set of features that allows you to import, edit, and export HLG content in Premiere Pro with a focus on professional broadcast workflows.

The following codecs are currently supported in Premiere Pro.

Before you begin

System requirements

Proper HDR monitoring requires dedicated I/O hardware and an HDR compliant reference monitor or UHD television hooked up using SDI or HDMI 2.0 or greater. 

Using AJA?

Adobe recommends:

  • HDR Compatible devices from AJA
  • AJA driver version 16.0 or higher for best results

  1. Click Premiere Pro > Preferences > Playback (macOS), or Edit > Preferences > Playback (Win).

  2. Click Setup next to your AJA device in the list.

    Setting Playback preferences
    Setting Playback preferences

  3. Choose the HDR color space.

    • 10bit HLG is recommended.  It can sustain UHD 60p and has broad support for displays.

    • 12bit HLG is limited to 30fps @ 3840x2160 (a bandwidth limitation of the AJA hardware) and not all monitors support it.

Opomba:

Adobe recommends that you only make changes to the HDR color space in Premiere Pro.  Making changes to HDR color space in the AJA control panel and in Premiere Pro can cause unexpected results.

Using BlackMagic Design?

BlackMagic Design has HDR capable devices in their Decklink and Ultrastudio lineups

  1. Click Premiere Pro > Preferences > Playback (macOS), or Edit > Preferences > Playback (Win).

  2. Click Setup next to Blackmagic playback in the list.

    Setting Playback preferences

  3. Choose Color Gamut: Rec. 2100 HLG.

 To improve performance, deselect unused video devices

Import HLG content into Premiere Pro

  1. In the Lumetri Scopes panel, select the Wrench icon, and set the color space to Automatic.

  2. Import HLG media (File > Import) into Premiere Pro.

  3. Drag a clip from the Media Browser or the Project panel on to the timeline.

    Premiere Pro automatically sets the new working space to Rec.2100 HLG. Lumetri Scopes also automatically switches to the correct color space based on the selected sequence or media.

Preview rendering

If effects or adjustments are added that require rendering for smooth playback, you can render the sequence while maintaining HDR range and color space.  When a sequence is set to the HLG color space, the video previews are automatically set to ProRes HQ at 1920 x 1080. 

Choose ProRes 4444 if you want higher quality color encoding. You can also change the video preview file resolution, however, you cannot choose any other codecs for the preview file codec. 

Speed up your exports by selecting Use Previews while exporting.  This option transcodes frames from the preview files, rather than reprocessing the effects.   

If your final deliverable is ProRes, save time by setting the preview rendering to match your deliverable specs. At the time of export, choose Match Sequence Setting and Premiere Pro copies the rendered frames from the preview files without encoding or processing the effects again.  You can render as you go, and export quickly. 

Export sequence

Premiere Pro provides sequence presets for ProRes and XAVC-I. You can also create your own presets especially to get the audio channelization correct for your specific deliverable.  All our presets have Stereo audio. Follow these steps to configure a proper encoding by hand. 

  1. Click File > Export > Media.

  2. In the Export Settings dialog box, choose the format from the Format drop down option (Quicktime or MXF OP1A).
