Pseudo-live or simulive streaming makes it easy to stream pre-recorded videos as if they were ‘real’ live streams. Viewers won’t notice any difference. If you have the opportunity to pre-record your event, there are many reasons to opt for a pseudo-live stream. Even if you can also broadcast live, a simulated live stream is often the better option.
Simulive streams allow you to stream multiple simultaneous live sessions in HD with closed captions and audio translations without breaking a sweat
Clevercast Player can be embedded in your site and in most 3rd-party platforms (eg. Swapcard, Hubilo, Docebo, Slido …) by simply copying the embed code. But a pseudo-live stream can also be used in our multilingual, webinar and e-learning applications, or as the source of a simulcast to social media channels. The possibilities are endless.
Global CDNs are used to deliver the live streams close to your viewers. The number of viewers is unlimited.
Reliability and quality
Pseudo-live streaming guarantees video streams of the highest quality.
- When recording in advance, you can ensure your video quality is optimal. Even if something goes wrong, you can still fix it.
- By not having to send a live broadcast, you avoid production issues, encoder troubles, quality loss due to a lack of bandwidth, and all kinds of connection problems.
- Your pre-recorded video is transcoded to multiple resolutions for adaptive streaming (optimal viewer experience on all devices). For a ‘real’ live stream, this is done in real time which limits the possibility of video compression. When the video is uploaded in advance, Clevercast uses two-pass encoding with high quality settings for each of the resolutions.
Ease of use
Pseudo-live streaming makes your life as a live stream producer a lot easier. Instead of managing a complex live production, all you have to do is upload a video file and schedule the time of your live stream.
- Just upload your recording when it’s ready. Clevercast does the rest: transcoding it to multiple resolutions and getting it ready for broadcast. If it turns out that the video still needs to be adjusted, you can simply upload a new video.
- Once Clevercast has processed your source file, simply set the time at which the live stream should begin. That’s all. Sit back and watch the live stream run at the scheduled time.
Pseudo-live streaming can save you a lot of money. Not only do you avoid the broadcasting costs, but the data traffic costs will also be a lot lower.
- A live broadcast requires labor and resource costs. At the very least, you need an encoder and someone to monitor it. With a pseudo-live stream, you only have to set the start time in advance. Nothing needs to be done during the live stream.
- When the video is transcoded beforehand (not in real time), each of the streamed resolutions will have a higher degree of compression. This means that your viewers consume less data traffic while watching the stream. On average, data traffic usage is 30 to 70 percent lower (if the video content is static and computer-generated, the percentage will be higher) for pseudo-live streaming. If you have a large audience this will reduce costs substantially.
Simultaneous and multilingual live streams
Pseudo-live streaming makes complex setups possible, such as multiple live stream sessions that need to start simultaneously or live streams in many different languages (audio translation and closed captions / subtitles).
- Pseudo-live streaming lets you start a large number of live streams at exactly the same time. Without stress, since everything is scheduled in advance.
- Pseudo live streaming is an ideal solution for multilingual live streams. An optimal quality of the translations can be guaranteed since everything is done in advance. This is possible for audio translation as well as for closed captions / subtitles. During the live stream, viewers can select their preferred language via a dropdown menu in Clevercast Player.
- If you use Clevercast to broadcast a ‘real’ multilingual live stream (with or without Translate@Home) you can use the server-side recording to schedule a pseudo-live stream to other time zones.
If you use Clevercast player to display the live stream – whether it is as part of a Clevercast application, embedded in your site or in a 3rd party platform – you also get all Clevercast features. These include:
- Adaptive live streaming: Clevercast player switches dynamically between streams with a different resolution and chooses the most suitable one for the playback device (depending on screen size and bandwidth, memory, available CPU and GPU resources) to avoid the video stuttering or spinning.
- Controlling availability: you can whitelist and blacklist domains, IP addresses and countries to limit the availability of the stream.
- Player countdown: the player can be configured to display a countdown timer until your live stream starts.
- Poster images: you can upload images to be shown in the player before and after the live stream starts.
- Interactive messages: during the live stream, you can show messages in a player overlay
Pseudo-live streaming can be combined with a live broadcasted Q&A session afterwards. You can configure Clevercast player to automatically show a paused image when the pseudo-live stream ends. When you start broadcasting your Q&A session, this image will automatically make way for your live stream.
Pseudo-live streaming is also possible without using Clevercast Player. The live stream is sent using the standard HTTP Live Streaming (HLS) protocol and can therefore also be played in most other players. Please note that we don’t provide support for issues with 3rd party players.
