“EDIT: I have just had confirmed that what you are seeing on the screen is from the 1dmkIV menu. Sorry to disappoint. We will have to wait a little longer!”
So, Tim Smith (in the video) discusses 24p and 60p, the video shows the Canon EOS-1D MKIV menus.
@tylerGinter tipped us today of this video which shows a little taste of the firmware Canon's working on for the Canon EOS 5D Mark II. The video shows not only 24fps, but 720 at 60fps. Canon's announcement a while back said 24p but didn't mention the smaller size with 60fps.
Watch at about 5 minutes in where Tim starts talking about what is in the firmware. The beginning is discussion of the history of the Canon EOS 5D Mark II and video.
The title of the video on youtube is:
“Createasphere – Canon Intensive Workshop – Canon EOS HD Video: Shoot, Post and Deliver – Playback”
(I don't think the description really matches the video so I'm not including it here).
Thanks for the tip Tyler!
