It seems YouTube is standard de-facto for video hosting. A new digital cameras from Casio can be visual proofs of that thesis. The EX-S880 and EX-S77 feature 8.1- and 7.1-megapixels respectively and include special YouTube capture mode. That mode allows to store your videos at 640 x 480 resolution and H.264 format. So, you shouldn’t adjust your video and convert it to proper format.
Both cameras will be out in August for $300 and $230, respectively.
