Does the HDMI uncompressed video from Canon EOS 5D Mark III firmware look better?

by planetMitch1 Comment

Our good friends over at LensProToGo have just put out a sample video showing the differences between the data written to the internal storage vs. the image written to the Atomos Ninja-2 via the HDMI out thanks to the new Canon EOS 5D Mark III firmware 1.2.1.

The results are interesting and I'll let you tell me what you think in the comments for this post over on the planet5D forums.

Description from LensProToGo

n this video, well do some video footage comparisons between the Canon 5D Mk III internal compressed format and the new uncompressed clean HDMI out via the new firmware update. All footage was shot using the Atomos Ninja 2 in Apple ProRes 422 HQ. Were using timecode record command on the camera to simultaneously record to the card and the Ninja 2. Watch in full screen for the full effect!

  1. This test really doesn’t show a significant difference. Get the footage in after effects and start pushing it around. That is where you will see it. The Ninja has none of the awful “blocking” in the dark areas. It is worth the money if you are going to be doing any type of color grading.
