Canon EOS 600D / T3i does NOT have clean HDMI output
http://wasge.es/clean_output/?brand=Canon&camera=EOS%20600D%20/%20Rebel%20T3I Even with the latest firmware, the Canon EOS 600D / Rebel T3i does NOT have a clean HDMI output. This means it always outputs some texts or icons, making it not ideal for live video streaming or HDMI external recording. You may get a "clean" rectangle when recording, which you could crop and resize to full screen, but it's not a real clean HDMI signal.
