The full spec table
Captions are not optional here
LinkedIn is scrolled at desks, in meetings and on trains, and the sound is off. A video that only works with audio effectively does not work on LinkedIn. Burn captions into the file or upload a subtitle file, and design the first 3 seconds to make sense silently.
Company Page vs personal profile
Schedulers publish to Company Pages through LinkedIn's API, and Page publishing has its own permission model: the connected member needs an admin role on the Page, and tokens expire on a schedule. When a LinkedIn post fails while every other platform succeeds, an expired token or a changed Page role is the cause more often than the file. The troubleshooting guide below runs through the fixes in order.

The same master video works, but the LinkedIn cut should lead with the business outcome rather than the entertainment beat. Our one video, five platforms guide shows the adaptation pattern in full.
