LinkedIn has introduced an embedded video process. This can make it easier than ever to make your posts reach a vast audience interested in varying subject matter. In order to include video in your post, you will need to perform a few actions. The first is to remove all shorteners from your posts. LinkedIn will only embed video if it detects a full, unshortened URL and detects video from that URL. To remove shorteners, follow the below steps:
1) Click on Socials
2) Click on your LinkedIn account
3) Click Edit
4) Click on Links
5) Select Don't Shorten Links
From the same Settings, you can also make sure that your posts are set as Shared Links. You can find this Setting on the default tab when you open the Edit section of your Social.
