Is Motion a good choice to create narrated educational videos?
I'm interested in creating educational videos from a few minutes to one hour in length. The content starts as a script which is then recorded as an audio narration. I'm wondering if I could then import the audio and assets (simple vector graphics) into motion and animate them in sync with the narration. There would be multiple scenes in terms of animations but the whole thing needs to be on a single timeline to keep my sanity. This would be a low budget project. If you've watched YouTube videos by CGPGrey you get the picture. He uses FCP which I think is overkill and doesn't seem to be the best fit. There are a lot of people interested in creating such videos and I'm surprised Motion never came up as a tool. I've watched a few tutorials and get the impression Motion is mostly used for shorter animations that are then brought into FCP.
Is there a reason I shouldn't use Motion for this project?
Would you recommend any alternatives? The closest thing to what I want seems to be Flash (now Animate) but I find it prohibitively expensive. Keynote has most of the basic tools I need in terms of importing content and animating it (really just moving things around), but it lacks a timeline and this is really not what it's designed to do.
