Please check out the Tahoma 1.0 that just came out.
It's a fork of OpenToonz that now has canon dslr input.
That means that it has all the advantage of being a traditional animation software.
You can combine traditional animation to your set.
Make hand animation as reference
If you have a video projector you can use it for synchronized animated light effects.
That alone is a total game changer. You can make rain, storm and blistering lightning so easy. Or track a sniper dot. Make disco lights. Gobo's etc...
I haven't seen this kind of feature anywhere else
And it's free
