I'm on Linux Mint, and need something very simple to turn a sequence of shots (by my daughter and her friend) into an animation. I know about mencoder, but I need just a little bit of control: this is the girls' first animation, so some scenes have been animated in quite small steps, but others are much more rough. If played at a uniform frame rate, the resulting movie would look really weird. Is there any tool where I can set how long a given frame should be displayed (so it's rendered 3 or 15 or whatever times into the outgoing video)? Alternatively, a simple text-file based tool would work, with timestamps indicating when a given frame should be inserted into the movie.
Thanks in advance,
