How does a BMCC 2.5k in Raw mode compare to
a Canon 5d Mkii in h264 mode at 12800 ISO?
(skip to 2:19 for actual test -or stick around for the details)
Settings for each camera:
50mm Lens @f4 - 1080p 24p - Standard h264 recording to CF card.
Set to 12800 ISO on the camera.
“Standard” PS with 0 Sharp, 0 Contrast, -1 Sat, 0 Colour tone
24mm Lens @f4 - 2.5k Raw 24p
Set to 1600 ASA in Camera
Post Production for each camera
Despite the WB being set as Tungsten, it was slightly off - so very minor correction for WB in post. Converted to Cineform Film scan 2 DI for post.
At Exposure 0 the footage was 1600 - so it was set to 3 - pushing 1600 +3 stops reaches 12800. This is a total of +4 stops of digitally pushed footage from the native asa of 800. Added some contrast and Sat from the BMDFILM LUT.
Because the 5D has in camera NR, and the BMCC does not, I only applied NR to the BMCC.
Whether the footage is suitable or not is subjective,
the answer depends on your own standards and
To get results like this from the BMCC, I still needed to film a scene with lighting. If you film a scene with too little lighting at such a high ISO value, you will mostly just get noise and artefacts. While 12800 is a very fast film speed - do not expect to see miracles if you fail to light properly.
Thank you for watching.
