This video was shot with a Canon EOS 600D/T3i using a beta version of Magic Lantern that enables ALL-I recording with high bitrates. This video is really a "proof of concept" in the quality that can be achieved relative to the original Canon firmware. To really judge this, feel free to download the original file (encoded at 90 Mbps avg after applying some light color grading and adding sharpness). If you just watch on Vimeo, you really aren't seeing the quality difference that the bitrate represents due to Vimeo's compression at a low bitrate.
Shot using the 600D/T3i's 3x zoom (crop) feature with a Zeiss 50mm 1.4 ZE lens.
The rightmost panel is using the Canon original settings (GOP=12) and has a bitrate of about 40 Mbps. The middle panel is ALL-I (GOP=1), which has a bitrate at 169 Mbps (constant). The leftmost panel is GOP=3. which peaked at 170 Mbps and averaged 149 Mbps. The second half of the video is at 300% zoom in post.

Thanks especially to 1% for his development of this beta version. This is a very promising development. I sincerely hope it makes it into future stable releases of ML.
