The Twitter Video Player will support formats files “mp4” and “mov” on smartphones with 16:9 aspect ratio, according to documents leaked by a developer. Videos can be up to 10 minutes.
Whether accidentally or intentionally, Twitter unveiled a document in its FAQ describing an upcoming video service like YouTube or Vimeo.
It was originally discovered by a San Francisco resident Daniel Raffel who develops snapguide.com. Looking at the Twitter FAQ he was surprised to see that it explicitly states that the service supports MP4 and MOV formats, and that videos should be encoded using the H.264 standard with a 16:9 aspect ratio and AAC (low complexity) audio codec.
They also report that the users they should ensure that their clips do not exceed 10 minutes and the video bitrate should be at least 5000K bits, while the audio bitrate should be 128k.
"Right now we don't have a limit on its size archivey while uploading. Therefore, we encourage our users to use its highest resolution source video, to have an optimal user experience. However, keep in mind that the larger the source file, the longer it will take to upload the file,” the FAQ states.
The FAQ also describes how to use Twitter Video Player. You can see above details here.
