Credits pay for outside readings a file needs, charged per whole measured minute with a one-minute minimum. Failed readings are refunded.
Credits pay for the outside readings and intelligence work a file needs, such as checking whether footage was machine-made when the file carries no credentials of its own.
Video and audio are charged per whole minute of the file measured length, rounded up, with a one-minute minimum. A 90-second clip and a 90-minute film are never charged the same.
The credits go back on that file, once, with the reason named. If a file length has not been measured yet, nothing is read and nothing is charged.
No. A free account gets the honest Unknown and the offer to move up rather than a reading we pay for.
