All the footage was shot in HD on the EOS 7D, but due to indifferent lighting conditions the ISO boost ended up leaving a ton of digital noise. This is why the video is not HD, and has been turned to black and white. It still sort of works.
If I plan to shoot further layout video, I think I will need to do it under stricter conditions, bring my own lighting and have a plain backdrop to avoid distractions. I will also need to shoot the same movement from several angles, so a proper story can be made. Live and learn.
