I have a pro licence and am now getting watermark 'lrtimelapse.com' over my rendered shots.
How do I disable it?
thanks

In the LRTimelapse render dialog on the right side you can activate and deactivate and configure the watermark.

Okay my mistake.
The copyright overlay box had been kicked by mistake.

Let me take this opportunity to tell you I'm having a blast processing all my library of timelapse shots. LRT3 is very intuitive even for a clack kicker like me.
A little tip I discovered - I have canon mk3's now but a few years back I was using a Nikon D700 with a dirty sensor. I found I can now clean up the spots using spot removal on lightroom 5 after I've read the processed LRT metadata and before exporting from LR5. You all probably know that but for me in my cow shed its a big leap forward.
