Stream tool

This chapter explains how to operate a stream on the live stage. See the section on Streaming for information about how to set up and send a stream to UpStage.

Click on the Stream tool in the left-hand tool bar. This will open an overlay at the top of the screen showing icons for all available streams on this stage as well as a “refresh” button.

Drag the icon for your stream onto the stage. You will see first a buffering icon before the video appears.

Streams are held and operated by one player, in the same way as avatars.

Show your stream on stage

The stream has the same “light bulb” icon as props and avatars; until you activate this (it is green when activated) your stream is not visible to anyone else. It will show as black and white to you, and you can adjust parameters such as the size, position and opacity of the stream before turning on the light bulb to make it visible to everyone.

Once you have turned the light bulb on, turning it off doesn’t make the stream invisible to others. It allows you to make changes to the stream (such as size, position and opacity) that won’t be visible to everyone else until you turn the light bulb on again. They will still see your stream while you are making the changes.

Adjust size, position and opacity

The green frame around your stream allows you to adjust the size, position and opacity of your stream – the same as you can do with props and avatars. If you don’t see the frame, click on the stream and the frame will appear around it.

  • Drag and drop to move the stream to another place on the stage.
  • Use the corner and side handles to scale the stream to be larger or smaller.
  • Click and hold the white circle at center top, then drag it to rotate the stream.
  • Move the slider on the left-hand side down to reduce opacity (fade out) and up to increase opacity (fade in).


The speaker icon at the lower right of the stream is a local mute button. Clicking on this will mute the audio of this stream for you and only you. If you are sending an audio stream you will usually want to mute it locally so that you avoid generating feedback and don’t have to listen to yourself.

To mute or control the level of your audio stream for everyone else, you must adjust it in the streaming software (e.g. Larix or OBS)

Stream shape

Video streams are rectangular. If you would like your stream to appear as a circle or oval, right-click on the stream. A context menu appears with the circular frame option at the top of the list. Click on the circle to give your stream a circular frame.

A rectangular stream will become an oval. To make your stream round you will need to choose square dimensions in your streaming application’s resolution settings. See the chapter Sending a Stream for more information.

Play video

You can play pre-recorded video by sending it as a stream.You will need to consult the documentation for whichever streaming application you are using (such as Larix Broadcaster or OBS) for more information on how to do this.

Remove a stream from the stage

Right-click on the stream to see the green frame, then click on the cross. The  stream will disappear from the stage. It is still available in the stream toolbar if you want to put it back onto the stage.
