I know that Clean HDMI has been a hot topic for all of the canon cameras over the last several years - especially the 6D. While I have been a programmer for 16 years, I have never gotten into firmware development - so I apologize in advance if what I am about to say has been discussed. But here it goes...
In the playback section of the 6D, Canon pushes HD video to fullscreen NATIVELY while the video playback overlay remains in 3:2. For pictures, it black bars the sides and scales them into 3:2 WITHIN a 1080i frame. This is unlike the HDMI out LiveView as it sends a 1080i image with video WITHIN black bars. So my question is, could the secret to Clean HDMI out be hidden in the settings for playback? I mean, if this has to do with finding the appropriate register settings (apologies if my terminology is incorrect for assembly), then wouldn't the appropriate setting be revealed within that portion of the firmware?
And if so, then enabling/hijacking that setting for LiveView would give external recorders uncompressed 1080p at 16x9...
