Video requirements by platform
Video limits differ more than any other rule: maximum length, file size, formats, frame rate and resolution all vary by platform. These are the enforced limits; Zolyp checks duration, size and format before a video is scheduled, so it isn't rejected at publish.

Common questions
How long can a Facebook video be?
Zolyp publishes Facebook video as a Reel, so it has to be 3 to 90 seconds long and vertical (9:16).
How long can a video on X be?
Up to 140 seconds (2 minutes 20 seconds) on standard accounts; longer videos are rejected. X Premium accounts can post longer videos.
Does Zolyp check a video before it's scheduled?
Yes, for what can be checked up front: duration, file size and format. A video outside those limits is flagged before scheduling rather than rejected by the platform at publish.
