Limitations & Bugs

Here is a list of things Excalibur can't do. I break them in two categories:

  • API limitation – this means, there is nothing in API that will allow to do this. Though, maybe I will be able to find workaround.

  • Premiere Pro bug – it's a bug, so hopefully, it will be fixed at some point by Adobe team.


IMPORTANT: I didn't find the way to distinguish when Premiere Pro has text-box activated. That means if you have Excalibur shortcuts that only use letters or letters with shift modifier (A, shift+A) and whenever you type text (subtitles, name of a track, anything), when you will press that key, Excalibur will execute command assigned to it.

To avoid this, use ctrl, alt modifiers or multiple modifiers at once.

Paste Clip

Paste Clip command won't work with clips that were cut (not copied) in Premiere Pro 2019

Mask effect

Masks (e.g. in Opacity effect) are not supported.

Lumetri effect

When applying video preset with Lumetri Color, color wheels, curves, anything that has some kind of graphic interface, will be set to default

Color parameter

If preset has colour value with keyframes (e.g. Tint), colours at keyframes won't be correct.

Transition presets

Transition presets can't be applied


  • When applying effect preset, influence (length of keyframe handle) for all bezier keyframes will be set to 16.6%
