re: Question About Recording Gameplay With Audio on XB1...think Youtube Gamer/Bloggers

Most people do it through a computer. A basic setup using a console might be something like:

1. Xbox video and audio output to a capture card on the computer.

2. Webcam video and audio output to the computer.

3. Broadcast software interface (like OBS) to sync the video and audio inputs and other text/images on the screen, set the quality, etc.

4. Output that to a file and upload to Youtube or output that to a stream and upload to Twitch (or do both).

Your computer needs the processing power to handle the two sets of inputs, running the broadcast interface, and compressing the output. If your computer is lacking in power, you'll have low quality or "jittery" output.

ETA: If you're playing the game on the computer already through Steam or something, replace step 1 with that. You'd still capture that audio and video through your broadcast interface in step 3.

ETA 2: If you're streaming, you'll need an internet connection with enough upload throughput for whatever video/audio quality you're trying to stream at. So your bottlenecks there are computer processing power first, then upload capacity second.
