If it fits with what you're trying to do, I would recommend instead turning the vids into gifs (pornhub has an online tool to do this for vids hosted with them if I remember correctly) and then post those with a link back to the source video. An upside to this is Tumblr blogs that have original gifs, as in ones with your own watermark and clips that haven't been seen elsewhere gain new followers, reblogs and likes much, much, much faster.
