What is Asynchronous Video?
Asynchronous video is recorded, uploaded, or processed independently of real-time interaction. Its creation, transformation, and viewing can therefore occur at different times.
How Asynchronous Video works
Asynchronous video separates capture, processing, distribution, and viewing into independently scheduled stages. Unlike a live session, it can be transcoded, captioned, moderated, and packaged before an audience requests playback. The delay enables heavier optimization and review but introduces a period in which an upload exists without ready renditions. Media systems can model that transition explicitly and notify publishers, or expose status for polling, when required derivatives become available.
Key facts
- 1Because playback is not tied to capture time, encoders can use slower multi-pass or quality-targeted strategies that would be impractical under live latency constraints.
- 2Recorded media can be packaged into downloadable files or segmented adaptive streams; “asynchronous” describes timing of participation, not a particular container or codec.
- 3A completed upload is only the first durable milestone: thumbnails, captions, transcodes, moderation, and publishing may each fail or finish on different schedules.
When Asynchronous Video matters
Recorded messages and uploaded presentations use asynchronous delivery when participants need not be present together. Background transcoding adds completion delay but avoids tying long jobs to live requests.
