VideoTweet provides an easy way to publish the best part of your videos without worrying about Twitter's requirements. The image is converted to the right format, reduced to the maximum size and length that Twitter allows and finally compressed to make the upload as fast as possible.
Of course, we do this whilst maintaining the best possible image quality. The free version embeds the hashtag and link of the app creators with every tweet.
