Start with system audio
System-audio captioning works from the digital sound your Mac is already playing, avoiding microphone echo and room noise.

Place the floating subtitle bar near your visual focus, increase the type size, and keep enough recent text to preserve context.
Know the limits
Protected media, overlapping speakers, heavy music, and specialist vocabulary can affect capture or recognition quality.
