I've experimenting some appsumo tools for cloud video editing and NOVA AI is the fastest one so far when you are editing (i've tested wavevideo, flexclip and others that i refunded and can't remember the name). I'm not sure if it is the fastest rendering the video. I've found some bugs (the texts were different after exporting in instagram story size), but i hope they fix this soon. Other thing they have to fix is that de site favicon is the Reactjs logo. My new tool for editing videos for social media. 5 tacos
