I play on a fairly potato-like system and I get minimal lag even when animating 10 items per second (the maximum speed allowed). Here is my system doing just that (while also running the capture software simultaneously):
Thank you :-) As for being tedious - that really depends on how complex your scene is going to be. You can throw together some animations (like the one in that last video I posted) in, what, under a minute? And I'm guessing some people might orchestrate entirely epic scenes, using hundreds of items, that might very well take 15 minutes to set up.
What I can definitely say is that I tried to keep the interface simple; this makes animating possible with just 4 steps:
1. Add furniture to the scene.
2. Position the furniture for the animation frame.
3. Add a new frame.
4. Repeat 2 & 3 as needed.
