This video was uploaded in 1080p (1920x1080)
This was shot with a 50mm 1.4 lens. All settings are constant. The only change is going from the default h.264 codec to raw using Magic Lantern v2.3 on the Canon 5D mark ii.
This is not an official test, but rather some results I found interesting when experimenting with the hack.
The raw files were converted to dng, then prores.
I think it's worth noting that when shooting raw, the mark ii caps out at 1880x720, a resolution smaller than 1080p. Although the resolution is smaller, the image quality is much more clear and sharp when recording in raw with a larger dynamic range.
It's interesting to see the smaller resolutions holding up against the h.264 even when upscaled to fit a 1080p timeline.
While recording, I did experience some frames being dropped, which is why I cut some of the clips short.
I look forward to shooting more raw footage. I'd like to experiment more with upscaling the 720p raw to 1080.
