Live Video Production in The Cloud

All the power of a professional hardware switcher—running in the cloud.


Access and control everything through your browser. No hardware, no complexity.

Cloud Switching

Create unlimited “Flows”—each containing different video sources, graphics, and layouts. Switch between them instantly during your live broadcast with a single click.

Switch between different camera angles

Switch to Commercial break

Switch to “Technical delay” screen

Mix Any Source in One Production

RTMP, RTSP, SRT Streams: Connect live camera feeds, encoder outputs, or other Castr livestreams.

Videos & Images: Add pre-recorded content, sponsor logos, or “Be Right Back” screens from your video library.

Web Widgets & URLs: Embed live graphics, overlays, or widgets from services like StreamElements and Singular.Live.

Dynamic Overlays & Graphics

Elevate your production with professional overlays, lower thirds, logos, and real-time graphics. Add web-based widgets as URL sources to display live updates, chat interactions, alerts, or custom animations.

Layer, position, and scale each element exactly where you want it. Adjust transparency, lock positions, or create multi-layered compositions.

Smooth Transition Effects

Create polished broadcasts with professional transition effects between scenes. Choose your transition styles and set precise timing down to the millisecond.

The Preview and Production split-view lets you see exactly what’s queued next and what’s currently live. You’ll never have a surprise on air. When ready, hit “Transition” for smooth, broadcast-quality scene changes.

Audio Mixing

Professional audio control for every source in your production. Balance multiple audio sources perfectly in real-time.

Independent volume control per source

Audio sync adjustment

Mute/unmute individual sources

  • Who is Castr best for?

    Hover

    Castr is best for anyone who wants to stream and host videos for any purpose, whether it’s for gaming, live church services, live TV or business conferences.

  • What is Cloud Production?

    Hover

    Cloud Production is Castr's browser-based live video switcher. It gives you the capabilities of a professional hardware production setup — scene switching, overlays, audio mixing, transitions — all running in the cloud. There's nothing to download or install. Just log in from any device and start producing.

  • Do I need any special hardware or software to use Cloud Production?

    Hover

    No. All you need is a modern web browser and an internet connection. Cloud Production runs entirely in the cloud, so there's no software to install and no hardware switcher to buy. If you're connecting live cameras, you'll need an encoder that outputs RTMP, RTSP, or SRT — but that's the only external requirement.

  • Can I add overlays and graphics to my production?

    Hover

    Yes. You can layer logos, lower thirds, text overlays, and real-time graphics on top of your video. Web-based widgets can be added as URL sources to display live chat, alerts, scoreboards, or custom animations. Every element can be positioned, scaled, and adjusted for transparency.

  • Is there an extra cost for Cloud Production?

    Hover

    No. Cloud Production is included in every Castr plan at no additional cost. There are no hidden fees for using the production features — you get access to the full suite of tools with your subscription.

  • Where can I stream my production to?

    Hover

    You can output your Cloud Production to a Castr Livestream and then use Multistream to broadcast simultaneously to YouTube, Facebook, Twitch, LinkedIn, and 30+ other platforms. One production, unlimited reach.
