This looks amazing, congrats!!

One quick note: on your features page, the trim section has the same text as resize gifs. You pasted the wrong copy there ;).

Again, congrats on your great work!

[EDIT] found one more: when I use your demo, the onboarding tutorial stops after step three. Regardless of whether I click next, click "skip", or drag the playhead marker, I never get shown step 4 out of 6.
