Umm, let me think now.
Currently retired, it's a long while since I had anything to do with patents.
As a general rule, do not
disclose anything prior to starting a patent application, which might put the new
ideas/invention into the public domain.
It's tempting, and, very easy to give the game away, if you are looking for backers to invest.
There are many clever people, looking to steal a bright idea for their own gain.
Once your super new invention is in the public domain you are legally 'stuffed' when it comes to getting a patent.
I wouldn't trust my own grandmother!
Personally, given the resources today, I would tend to forget about patents and manufacture and sell the machine/s, as quickly and profitably as I could (it's a winner, right?), keeping ahead of the competitive game, for as long as possible.
If you've designed an engine that genuinely runs on fresh air, or something similar, then that might be a different matter.
The most important thing with AnimationLab output, is that the quality allows your viewer to see what it is you are trying to show.
We are all lazy and quickly get bored, otherwise.
It's easy to review/edit/replace/delete, your efforts, once the movie has been uploaded to youtube.
AnimationLab has several movie templates to work with. They may suit your needs without alteration.
Camtasia is also good, and easy to use, but may be an unnecessary expense.
