How to Publish a Pre-Recorded Video as a Live Stream

These pre-recorded videos are well-pre-edited content for very precise and polished delivery. Unlike live streams, pre-recorded videos allow for adjustments on the visual elements, audio, and transitions to give a high-quality production. This flexibility makes them apt for various industries, such as:

‍Webinars and training: Deliver consistent, flawless tutorials accessible anytime.‍

Virtual events: Use pre-recorded sessions to avoid technological risks in live streaming.‍

Product launch: Display products with better graphics and fuller narratives. Elimination of live uncertainties pre-recorded videos have the aim of enhancing viewers' experiences with dependable and engaging presentations.

Why use pre-recorded videos for live streams?

Pre-recorded videos streamed live combine control, quality, and reliability in a way that is hard to achieve with live broadcasts. From a technical standpoint, here are some advantages:

‍

Bandwidth optimization: Pre-recorded streams take advantage of Adaptive Bitrate Streaming (ABR). This means pre-encoding content into different quality levels and adjusting the resolution and bitrate that the player will use during playback in real-time by matching what's available, thus giving a better buffering experience.

Reduced CPU and encoding load: Pre-recorded content is encoded offline as opposed to live streaming that has real-time encoding. As such, this will bring down the computational requirement when transmitting. This further means reducing the risk of a drop frame or overheating of such systems with reduced processing abilities.

Improved resource utilization: The pre-recorded streams can be hosted and delivered through Content Delivery Networks. This will reduce latency and quicken the load time for viewers everywhere in the world. Since the upload bandwidth of the host system is not used heavily, it is very much suitable for high-traffic events.

Error-free delivery: With the preparation of a video in advance, errors associated with live streaming are taken care of before the go-live date, such as audio levels that are variable, poor lighting, or connection issues.

Pre-recorded live streams combine the best of both worlds: flexibility and control of offline editing, along with the reach and engagement potential of live broadcasts. They, therefore, represent an efficient way to deliver high-quality, scalable content.

Best practices for streaming pre-recorded videos

To ensure a seamless and engaging experience when streaming pre-recorded videos, adhere to these best practices with technical insights:

Conduct comprehensive testing

• Perform a dry run to check for audio-visual synchronization, encoding settings, and network stability.
• Use monitoring tools like OBS's stats panel or third-party analytics to detect potential frame drops, CPU overloads, or bandwidth issues.
  

Optimize video quality

• Utilize tools for video compression to maintain high quality while reducing file size.
• Choose the appropriate codec (e.g., H.264 for compatibility or HEVC for efficiency) and resolution (720p or 1080p) based on your audience's devices and bandwidth.
• Ensure proper keyframe intervals for smoother adaptive bitrate streaming, typically every 2 seconds.
  

Strategically schedule streams

• Analyze audience data using tools like analytics or platform-specific insights to identify peak engagement times.
• Account for global time zones if targeting international viewers, scheduling streams to maximize attendance.
  

Leverage post-stream engagement

• Extract highlights or key moments from the stream using FastPix clipping features.
