No idea for the reason of your post at all : ) in any way other than standing corrected DPreview?! LOL
1) The same DPreview link has already been posted in one of my posts in the previous page of this thread, where you can check the DCI 4096 wide in the specs page, actually, instead:
https://***URL removed***/reviews/yi-m1-mirrorless-ilc-first-impressions-review/2
So, a typo by DPreview? ;-)
2) No one said 4K 24p, on the contrary, the word "if" written in my post means that if 24p would be present (so, according to DPreview as the other poster mercer also wisely pointed out in his post, it is not ; ) the bitrate would be higher because the fewer frames per second you (need to) record, the more bitrate you can reach going with a lower frame rate.
To pay attention to between the lines can always be useful :-)
