Automatic content validations is available during content upload phase.

For example, you may want to reject on upload:

•Any image without caption and credit (otherwise, how you can tell what's it about, and who made it?);

•Any image with resolution exceeding specified limits (not less than 70 dpi, not more than 300 dpi);

•Any image in an unsuitable color space (e.g. only RGB images and no CMYK, or opposite);

•Any image with size out of range;

•Any video longer than X minutes, or shorter than Y seconds;

•Any video with an unsuitable frame rate;

•etc.

All these settings are part of the upload workflow, and they get configured for each GN4 system. To configure, use the Parameters tab on the users and groups editing (Edadmin > Users and groups). You may want to set parameters on the group level, e.g. on the Everyone group.
