When you have access to an Align portal and at least one channel in that portal, you can search directly for specific videos on that channel. You'll first need to go to the URL of your company's Align portal page or channel page, with the steps explained here.
The portal page will show those channels in the portal that you have been given access to. In the example below, one channel is currently broadcasting live, while the other channel was live just recently. In either case, you would be able to access recorded videos, but we'll focus on the channel that is not currently live:
Once you have accessed the channel you wish to search from, the player will be playing either live content if the channel is live, or whatever off air content has been set for the channel. Below the player, you will see a tab for videos, a tab for upcoming events, and a search bar.
You can choose to browse through the videos displayed in the video gallery, but you can also search for a particular video. The search keywords are pulled from the name of each video. For example, we can see a video named 'Quarterly meeting' in the gallery. Were this video deeper in the gallery, we could surface it for play by searching for 'quarterly' in the search field, and hitting Enter:
By clicking on the thumbnail of the video in the gallery, the video will begin playing on demand in the player above.
