I put the camera in face detection, and of course the rectangle appeared around her face. I grabbed the Rebel T2i and asked my wife to take part in a technical research. A quick consultation with the legal department suggested that it would have been more cost effective to find another solution.Ī few weeks later, I had one of those D'OH moments, when I realized I was looking at the problem from the wrong side. I quickly reviewed my options: behead all actors, or find another solution. Because the rectangle will reappear as soon as an actor's face is detected. That is, if you don't plan to have actors in your shots. Set the focusing mode to face detection! In face detection mode, the rectangle does not appear and you can capture an image that's even cleaner than the one output by the 7D. Here's the deal: how to turn off the rectangle And the best thing that can be done is to move it to the edge of the frame: a less that ideal solution. The Canon 5D Mark II, as well as the rebels, still output a large focusing rectangle. And that's why Syndicate announced an HDMI capture solution for the 7D only. Unfortunately, only the 7D can provide an image clean enough. While not good as a full HD frame, it's still a 4:2:2 uncompressed signal, and can be upscaled to 1080p or downscaled to 720p with good results. Setting the cameras to 24p mode, the output signal is a 29.97 interlaced 1080i image, with pulldown, and large letterboxes around the frame. It's a non standard format, half way between 720p and 1080i. The signal output from the HDMI port is not a full HD, 1920x1080, frame. The red dot is unobtrusive and can easily be replaced using the H264 compressed material, or garbage matted away. On the other hand, during preview, only the small red dot in the upper right corner is displayed.

Most overlays can be turned off during preview, but not the focusing rectangle.
