You can render videos locally for free (single-threaded on your CPU), or use cloud rendering for faster processing. I'm trying to figure out if this approach actually saves time for people or if it's just a novelty. My main questions:

For folks who make tutorial/demo videos - what editing tasks eat up most of your time? What features would actually make you switch tools? Would you trust AI to correctly interpret your editing commands, or does that feel too unpredictable? What types of effects or edits would be most handy to control with natural language?

Curious to hear what would make this genuinely useful for your workflow vs just an interesting demo.
