Paying per video is a flexible alternative to paid subscription plans. It is a good option if you are not planning to create more than 2 HD1080 videos a month. Instead of paying a recurring monthly or annual charge, you can export and download videos as needed, by paying for that particular export only.
The price per video varies depending on exported video resolution. For a typical video, price for an HD720 and HD1080 versions will be $1.99 and $3.99 respectively. Please note that 4K videos are only available under monthly and annual subscription plans.
