Whip pan transition effect applied to text

[ed_welch]

I tried to add the whip pan transition effect to text, but couldn’t get it to work. This is the effect that I am talking about: Whip pan / swish pan Transitions?

It works applied to normal video clips but not if you have a text on it’s own in a separate track. The screen goes black during the transition.

Edit: I think the cross zoom effect causes the background to go black instead of transparent

I got it to work anyway by modifying the cross zoom shader. The problem is that it ignored the alpha channel.

Thanks for posting the solution. I’d be interested in which file you had to modify and which line(s) you changed.

I modified the “CrossZoom” shader in gl-transition-objects.js (just use vec4 instead of vec3 as in original)
