  • Make Dropdown Menu index change based on Layer parameter

    Posted by Tito Alverio on February 11, 2021 at 8:03 am

    I’m making a mogrt that contains my company’s slate template. I’m trying to make it dummy-proof and automate text based on selections in the Essential Graphics panel.

    I have a drop down for version names, (broadcast master, archive master, textless split, etc.)

    What I want:

    Based on the version name chosen, I want another dropdown (“audio track assignments”) to update with different index options. For example, if broadcast master is chosen, then the audio track dropdown will have 2 options: 1) stereo 2) stereo & M&E

    If textless split is selected, then the audio track dropdown will have 5 options, different from the broadcast master option. Is this doable?

    I think the only way to achieve exactly what you’re looking for is with scripting inside AE.

    If you’re trying to do this with a MoGrt, you can either set it with ALL the options but in different areas and maybe checkboxes. OR you could create separate MoGrts for each of your scenarios: Broadcast Master, Archive Master, Textless Split, etc
