What is "media" in UpStage?

"Media" in UpStage means a digital file such as an an image, animation, sound or video that has been uploaded to the UpStage server. These files can then be made available on your live stage as backdrops, avatars, props, audio tracks and streamed videos.

You must first create your media before it can be uploaded to UpStage. You can use existing media that is in the public domain, or that is available under a license that allows you to use it. Usually, you will want to create your own media that is specifically designed for the show you are creating. The following chapters in this section give some tips on creating media for UpStage, and then explain how to upload and manage media files on UpStage.

File formats

Here is a list of file formats that you can upload to UpStage:

  • Images: .png, .jpg, .jpeg, .gif, .svg
  • Audio: .wav, .mpeg, .mp3, .aac, .aacp, .ogg, .webm, .flac.
  • Video: .m4a, mp4, .webm, .opgg, .3gp, .flv

Small is Beautiful

UpStage is a venue for live online performance, and audiences can be located anywhere in the world on all kinds of devices and internet connections. In order to ensure the best possible experience for everyone, you should always keep media file sizes as small as possible. Data speed is more important than rich media. If you have a lot of media on a stage and the file sizes are large, it will take longer for the stage to load and real-time performance could be impeeded.

For these reasons, there is a default limit of 1MB for graphic and audio media uploads, and 300MB for video uploads. An UpStage administrator can override this limit for individual users, but this should only be done when there is a good reason.


UpStage uses a Creative Commons based system of permissions for all media items uploaded to the server. This allows you to restrict access to your media or to make it available for general use by other players on the same UpStage server. As an open source project, we believe in open access and sharing; however, as an artistic project we also understand the needs of artists to protect their work.

You should always keep copies of your media on your own computer in case of accidental deletion or failure of the UpStage server you have uploaded your media to; also, please delete unwanted media from the server - such as duplicate or replaced files, or media for a show that has finished and will not be performed again. UpStage is not a file storage service, and data storage is not free.
