Hello, I am making a short film about a live streamer (a person who broadcasts themselves on the internet doing various things, whilst people watch them and interact via chatting) and will be editing with Premiere Pro. My question is this: How do I emulate/add in an overlay like the one that live streamers use on platforms such as Twitch or YouTube, and show the comments that people make in the chat?
This is something that's going to be a lot easier to do in After Effects. You can create your design in Photoshop or Illustrator, and import it into After Effects to animate. Then you can either export your animation (or use Dynamic Link to bring your After Effects composition into Premiere with a live link), stick your video on top of it so it looks like everything is combined, and finalize your video.
This would be incredibly difficult and messy to do using only Premiere since you would need a ton of layer and would want to do a lot of keyframed animation. Maybe you can find a set of stock footage/animation that replicates the overlay feature?
