The Sony a77 is advertised to shoot 1080p video. In fact, it appears the sensor shoots something around 720p, which is further cropped by 20%. Then the whole low-res video is digitally upsampled to 1080p.

Cute, huh? I wish I could at least get out a native resolution video stream. It would save size, and limit degradation from upsampling to non-native resolution.

What do folks think? I'll cross-post to other forums later.

You mention the 1.2x crop factor for the a77 - it's more like 1.36. The a99 with IS enabled is 1.2x. The net effect with the APS-C crop is your video on the a77 is 1.86x.

Actually, that would imply just over 1.2x (based on APS-C cropfactor of about 1.53x).
