How to Use Castr Live Stream

A diffusion en direct is a great way to connect with your fans in real time.

Step 2: Check Your Connection

Your internet connection is very important. If your internet speed is slow, your video will freeze.

• Castr also supports MPEG-TS streams and IP camera streaming for more advanced setups.

Step 3: Pick Your Plan and Go Live

Before you start, faire sure your subscription plan allows for the number of sites you want to reach.

• Link your favorite streaming platform accounts to Castr.
• Press the “Start” button in OBS to send the données.
• Once the signal is pre-recorded or live in the dashboard, toggle each site to “On” and enjoy your stream!

• You can add password protection if you want to keep your video private.

Step 3: Monitor and Engage

It is time to check if everything looks and sounds great.

• Look at the preview window and the preview player to see your video.
• Make sure you have good audio so people can hear you clearly.
• Use google analytics to see how many people are watching from multiple destinations.
