In short, yes! Every guideline can be customised based on a variety of different criteria, such as brand, market, channel or even video length. Within this, you're also able to specify whether or not a guideline should be applied to videos, images or to both.
Please note that when we access In-Flight GIFs from Meta, we receive them as MP4 videos, and we cannot identify whether these videos began as GIFs.
Given the above, GIFs tested in Pre-Flight should be converted to MP4 before being uploaded to ensure that they will be scored as videos and therefore provide an accurate result before they are run In-Flight.
