Realtime VP9 at 1080p/12Mbps browns the box out on a weak PSU. Capture at most 1280-wide and prefer VP8 — the server-side transcode produces the final size anyway. Note: recording on the Pi still requires an adequate power supply (under-voltage occurs even at boot on the current one). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
