This tutorial makes it simple.

We will show you how to set up your account and start your first stream.

You do not need to be a tech expert to master these easy steps.

How to Use Castr Live Stream

A live stream is a great way to connect with your fans in real time.

With a castr account, you can send your live video to multiple platforms at once.

This means you can reach people on YouTube, Twitch, and other platforms with just one feed.

You can even use pre-recorded videos to look live!

To get started, you may need to click activate trial if you are new.

When you set up your stream, choose South America or whichever region is closest to you for the best results.

Step 1: Set Up Your Software

You need live-streaming software to get started. Most people use open broadcaster software (OBS).

• Find your RTMP URL and stream key in the Castr dashboard.
• Copy these and paste them into your encoder settings.
• This tells the software where to send your video content.

Step 2: Check Your Connection

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

• Check your internet upload speed before you go live.
• You need a fast internet connection to keep the stream’s resolution looking sharp.
• 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, make 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 data.
• Once the signal is pre-recorded or live in the dashboard, toggle each site to “On” and enjoy your stream!

How to Use Castr Transcoder

The Castr Transcoder is a special tool for live streamers who want a wider audience.

It takes one high-quality video and changes it into many smaller sizes.

This stops the video from freezing for people with slow internet. Castr offers this so your fans always have a smooth experience.

Step 1: Create Your Project

To start, you need to set up a place for your video.

• Log in to your castr dashboard and click create to start a new live stream.
• Give your stream a name and choose South America or the server closest to you.
• Use your streaming software to send the video to the cloud.

Step 2: Set Up the Player

Now you need to make sure your video works on your own website.

• Go to the settings and find the embed URL or the embed code.
• Copy this code and put it on your site so people can watch the live stream directly.
• 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.
• Keep a regular schedule to improve audience interaction, and save your videos in cloud storage for later.

How to Use Castr Cloud Production

Castr helps you stream even when your computer is off.

This is called video hosting for live events. It is very user-friendly, and castr works in your browser.

You can create a professional show by mixing video and audio from other sources.

This is perfect for a 24/7 livestream on social media.

Step 1: Upload and Organize

First, you need to get your files ready in the current location of your dashboard.

• Click upload to add your audio and video files to the cloud.
• Give your project a clear stream name so you can find it later.
• Castr’s products let you drag and drop files to create a playlist, for example.
