Nice video, it does look good.
I'm curious about your 4k workflow.
On the ML site it states the max res for continuous record up to 30fps is 1920 x 1080.
You claim to record at 1920 at 4:3 which = 1920 x 1440.
That would give you a 4k resolution of 3840 x 1440 when you unsqueeze the X2 anamorphic.
This would be great, except, as stated by ML, you can't record 4:3 at 25fps at 1920.
Can you please clarify with the correct information, as otherwise it's misleading.
Or correct me if I'm wrong.
Someone on the ML forum claims the max 4:3 resolution for 5D mkIII raw is 1600 x 1200. That would give you a 3200 X 1200 final image which is good but still sub 4k.
Or maybe your anamorphic is not X 2?
Can you post a link to a .dng or high quality jpeg of one of the 4k frames? I'd love to see the quality. This is the only way we can determine the validity of the title of your post since downsampling to 1080p for final output doesn't tell us anything about the captured quality of the image and wether it would make a viable alternative to 4k cameras.
