Option 2. Adobe Media Encoder. In case you don’t have it you can use a different option or install it from the Adobe Creative Cloud.
- Open a composition you’d like to render
- Go to Composition – Add to Adobe Media Encoder Render Queue…
- Click start render. It might take a minute but you should see Adobe Media Encoder opened and your composition added to the render queue.
