Capture Presets define the output format of a Recording (codec, container, resolution, audio channels, etc.). Before you can start Recordings with Just Control, you need to create one or multiple Capture Presets. After defining the Capture Preset(s), you can quickly access them in the Just Control Inspector. This accelerates the recording process and helps to keep things organized.

To make any changes within the Just Control Configuration panel, you have to unlock the panel first.

Overview

Open the Just Control Configuration panel, select a Device, and switch to the “Capture Presets” tab.

Capture Preset List: shows all available Capture Presets. Use the buttons below to add and remove Capture Presets. Double-click on a Capture Preset Name to adjust the Preset Name.
Capture Preset Configuration Options: Set options for a Capture Preset.

“TV Norm”: select the TV Norm.

“Audio Mapping”: use this option to change the audio output mapping for the recorded files.
“Do not write captions to container”: enable this option if you don’t want to write closed caption data into the recorded file.

Add a Capture Preset

In the “Device & Channel List” select a Device. Click on the “Capture Presets” tab and press the Plus ("+") button to add a new Preset.

Remove a Capture Preset

Select an existing “Capture Preset” and use the Minus ("-") button below the “Capture Preset” list to remove the selected “Capture Preset”.

Apple ProRes & Avid DNxHD/HR

When creating an Apple ProRes or Avid DNxHD/HR-based “Capture Preset” you need to select the Frame rate and Resolution, after selecting the codec option.

Audio Channels and Audio Track Alignment

You can choose between “2”, “4”, “8” and “16” Audio Channels for “Capture Presets”. Some configurations may require an Audio Track Alignment setting as well.

ToolsOnAir User Guide Central > [JIM] Capture Presets v.5.5 > alignment.png

note

Please note, that some codec/container options allow only “2”, “4” or “8” Audio channels as options.

Audio Mapping

The “Audio Mapping” feature enables the possibility to adjust the output mapping for the recorded video files of the incoming audio channels in a simple way.

note

You can set an Audio Output Track to “Silence” as well if needed.

H.264 Settings

When creating a H.264 Capture Preset you have to select “H.264” specific settings.

ToolsOnAir User Guide Central > [JIM] Capture Presets v.5.5 > h264.png

note

Note that “Custom” has to be selected as “TV-Norm”, when working with “H.264” presets.

There are different values and settings that can be customised within an “H.264 Capture” preset. Initially, the container type can be selected. There are two options available:

AVFoundation QuickTime
MP4

H.264 is a complex codec standard and is a bit more tedious to set up. Therefore, just:in mac provides various options, which can be modified within an “H.264 preset”. After choosing the container type, you have to define two general settings:

Resolution
Frame rate

Next, select the aimed “H.264 profile” and choose between multiple encoder profile options. Then you can set the Bitrate in bit/s, B-Frames, the GOP-Size, and the Entropy Mode.

Please note that some Mac Models have a built-in H.264 hardware encoder, which just:in mac can use for the H.264 encoding process. This happens automatically when working with an H.264 Capture Preset. If you are using a Mac without such an H.264 encoder, you will see a warning message in the Errors and Warnings Section within the Inspector.

note

Please note that not all custom resolutions are supported by the macOS built-in hardware encoder.

Growing Files

just:in mac supports growing files (for macOS and Windows-based NLEs) with various formats. If you have specific needs or questions, please do not hesitate to contact us. When working with Adobe Premiere Pro as your NLE of choice, please refer to this Adobe Knowledge-base article as well.

DaVinci Resolve

When using Blackmagic DaVinci Resolve working with growing files is possible as well, but only when using direct-attached storage. Tests with network-attached storage showed inconsistent behavior, and therefore it is not recommended. Please do not hesitate to contact us, to get additional information or to discuss your recording and editing workflow.
