Do not change these settings after your recording has started as it effects the generation of QuickTime file names and other Metadata. Doing so will result in errors in the XML structure and your media will be showing up offline in the Final Cut Pro or Adobe Premiere Pro project. 

Variables

A Variable is indicated by a leading "%" and a colored background. Variables can be rearranged using drag-and- drop. Fixed variables can be used by entering them without a leading "%".

Date & Time Format

Changing the format of these Calendar Event Variables is very easy and straightforward as well. In order to make this as flexible as possible, we are using the default system settings for that. To change that, open the custom format settings for “Dates” and “Times”, which can be found here:

Open the macOS System Preferences and open the “Date & Time” Preferences Panel.

Open “Language & Region” Settings.

Switch to the “Advanced” Settings.

Change “Dates” and/or “Times” Format Settings here ("Full:").
