AI speaker view means that the speaker will take up the full frame. You can choose different layouts for this as well. You can customize your clip and make it your own by adding a background. Riverside has some options to choose from, or you can upload your own. You can also upload your logo and readjust and reposition to your liking.
When you're happy with your clip, you can click Export. Decide on the specs of the final video, you can choose 720P, 1080P or even 4k but of course, this depends on what kind of camera was used to record. You can also decide if you want Riverside to normalize the audio levels in the clips and remove any background noise, like air conditioning and traffic.
