What is a minute? Is that how long the video is, or how long it takes to transcode?
We charge by the duration of all output files in minutes. This means that if you send us a 60 second video, and ask for two outputs, you'll be charged for two (2) minutes of video.
We do not charge based on how long a video takes to encode. That would be a crazy pricing model, because you'd have no idea how much you'd expect to pay, and we'd actually make more money if we intentionally slowed down our system. We want to be as fast as possible at all times.
