Kast is a great place to host watch parties with friends. You can create your own party, invite friends and share your screen or webcam from the web version and the PC or Mac desktop app. From iOS or Android, you can explore and join parties, watch streams, share your camera and chat.
To learn more about Kast web, read this article - and here is how you host a watch party from the desktop app:
1. Start or join a party
An easy way to start is to use the party that was created for you when you signed up. It is always on top of the front page, under "My Parties". Click the "Join Party" button
2. Find something that you want to watch with your friends
For instance a web browser, a game you are playing, or a video player.
3. Share your screen
When you jump into a party where nobody is kasting right now, you will see a screen that prompts you to start sharing.
Click the share your screen button on the very left, select if you want to share the full screen or one application window, then press "stream" to share your screen.
If you want to share both your screen and webcam, check this article for more information.
4. Enable sound.
Do this by clicking the microphone icon and the small arrow next to it that lets you select your sound source. Select "computer audio" to share the sound you hear with your friends. (Note: if you are a Mac user, you will currently need to install additional software to do this. Check out our help center article on this)
You can also do this by opening up the settings (gear icon in the top right corner of the video screen when you hover over it with your mouse), and then selecting your input & output (see image below).
Be also sure to have your microphone control unmuted - the microphone button currently controls all the audio that gets streamed to Kast.
5. Invite your friends
If your friends are not yet in Kast, you can share the invite link and drop it in social media or just send it directly to your friends. You can get the invite link by clicking the "copy party share link" button when you open up a party where nobody is streaming, or by selecting the "invite to party" button in the top right corner of the video screen (see image below).
That's it, have a great watch party!
If you are streaming an application Window and are having issues with black screen, you may want to disable hardware graphics acceleration on Chrome.
If you don't hear audio, make sure that the input is set to Computer Audio (or for Mac, see this article), and the microphone button is NOT muted.
Note: if others are using voice communications in the party, you should click on "mute all" in the participants list on the right side (see image below).
The "Computer Audio" setting streams all the audio from your computer. If you'd like to choose a specific audio source, a 3rd party app such as Voicemeeter is great. More audio options are coming to Kast soon.
