Welcome to TVPaint Community forums !

I'm trying to set up a camera move (for the first time), and am having problems. I clicked on the camera icon, and then set my start and stop camera frames in my project window. I opened the Time Profile and set the spline to start and end the move on particular frames. When I then scroll across the timeline, I can see the camera frame move across the project window. But when I click on the play button to actually see it play with the camera view, nothing happens. I'm just seeing my full project window.

What am I goofing up?

There's another small button in the playback controls right between loop and framerate, which does "play with camera view".

Well that was simple enough!
Thank you yet again Slowtiger!

Once I was checking a complete computer setup (hardware) for 20 min because I didnt see the "sound" button.

I probably would have been checking it out for 20 minutes before realizing it was unplugged.
