AV File Formats and Support

AVAnnotate references audio and video files hosted on other servers directly via URLs or through IIIF manifests.

Hosting AV

AVAnnotate does not host audio and video files. Making files available is made simple by uploading files to the Internet Archive where direct links to .mp3 and .mp4 files are easy to find. Simply follow the download directions and instead of downloading, click on the file name and copy the URL to the file.

Valid Formats for IIIF Manifests

Only File Paths, HLS, and DASH references will generate a valid IIIF manifest.

Video

  • File Paths: Video files directly hosted on a server or accessible via URLs, such as MP4, MOV, AVI, and MKV, etc.
  • HLS (HTTP Live Streaming): Live and on-demand video streams using HLS

  • DASH (Dynamic Adaptive Streaming over HTTP): Video streams using DASH

  • Audio

    File Paths: Audio files directly hosted on a server or accessible via URLs like MP3, WAV, OGG, etc.
