Length limit for clips?

I usually keep mine to 15 seconds but I have a clip that is 60 seconds long that I really don't want to cut into 15 second increments

I let my camera run for 60 seconds to capture it, well, for 60 seconds

Does P5 have a limit up to which they'll accept? Do 60 second clips sell?

you can upload between 3 seconds to 60 seconds on pond5. source: https://contributor.pond5.com/getting-started/preparing-your-files-2/footage/

*note: other stock sites are usually demanding 5 seconds minimum instead of 3 seconds
