If you like to create short video intros, Youtube intros, or promo videos, an affordable option is:
You can render 1080p resolution video clips for 7 dollars.
Another option is Clip Champ, with subscriptions starting at 11 dollars a month.
It has hundreds of stock videos, effects, and text transitions.
The interface is identical to Movavi's video editor; it has the APP and also the online in-browser editor.
A good online resource is Resize-Video, you can free convert a small video from 720p to 1080p (up to 500MB in size). The video is then saved without a watermark, is totally free, and does not lose quality. Guaranteed; I've tried it.
You can also go to Fiverr and hire freelancers to edit video intros for you.
