Encoding as Rented Infrastructure
Ben Ruedlinger, CINO at Wistia, on the video hosting infrastructure stack
The real shift is that video encoding has moved from a core product decision to rented infrastructure, which lets new video companies spend their time on the user experience instead of on file formats, pipelines, and delivery. Mux and similar APIs turned a hard engineering job into a simple developer workflow, while Wistia kept an advantage because it built that layer earlier and can spread those fixed costs across its own product and margins.

For a startup, the practical alternative is no longer build versus buy, it is ship now versus lose time. Mux describes the product as handing over a file and getting back a working playback URL, with transcoding, storage, and delivery handled underneath.

The companies that still build more themselves are usually the ones where video is mission critical and huge in cost. Wistia says outsourcing key video infrastructure would not work at its scale, while Mux says its value is sitting at a lower abstraction layer than Wistia, Vimeo, and YouTube.

What gets commodified is the mechanical work of preparing video files for playback. The value moves up into faster workflows, analytics, interactivity, search, branding, and systems of record. Milk Video even describes replacing parts of Mux with AWS Lambda and FFmpeg once its own workflow became clear enough.
From here, more of the stack becomes invisible. Encoding, captioning, cropping, and even basic editing keep getting wrapped into default APIs and browser tools, while winners differentiate through the application layer, where teams create, publish, measure, and reuse video inside a broader business workflow.
