Just like the title says, I'd love to see more preset transitions. If its doable in Adobe I can't see why it can't be done in HitFilm.
Along that and being specific...
A blur cross dissolve would be nice. This is stock on other editors.
A smearing/angle bluring wipe like thing would be nice.
Yeah I also would love to see a lot more transitions built in...for example glitch transitions.
This forum is precisely for this:
I am committed to creating Presets, Animated Templates and Transitions.
And share them in this forum.
