Shorthand supports videos in many formats. When you upload a video to your story, we will convert your video files to formats that are compatible with HTML5 web browsers, and attempt to produce a version of your video optimally sized for best viewing on the web. This may mean your video is re-sized to no larger than 1080px high in landscape, or converted to MP4 and WEBM formats.
For more information about compatible video, see:https://en.wikipedia.org/wiki/HTML5_video#Browser_supporthttps://en.wikipedia.org/wiki/HTML5_audio#Supported_audio_coding_formats
Maximum upload size is 100MB, and maximum video duration is 10 minutes, but videos should be kept as small as possible.
