Remarkably, it seems Twitter is not limiting the size of the video files, and is “encouraging partners to use the highest resolution source video.”
The word “partners”, however, may prove portentous, suggesting that the Twitter Video could be aimed more at brands and businesses than regular users. Videos must be uploaded directly to Twitter Video, rather than in the form of a link to an existing video URL, which Twitter will hope severely marginalise YouTube.
