The old way: frozen media
In the current paradigm, content is rendered once and stored as a file. A song is mixed down to MP3. A moves compiled to MP4. A document is exported to PDF. The rendering happens at publication time. The consumer gets a fixed artifact.
This creates three problems. First, the consumer cannot adapt the content to their context — a song mastered for headphones sounds different on a car stereo. Second, the artist cannot update the content without publishing a new version. Third, the provenance chain is broken — you don't know who created each component, who modified what, or whether the content is authentic.
JIT rendering solves all three. Content is published as its source components — tracks, scenes, data, templates. The rendering happens at consumption time, on the consumer's surface, under their preferences. The artist remains in control of the source. The consumer gets a personalized experience. The provenance is preserved.
Why it matters
JIT rendering transforms the economics of content. Artists retain ownership of their source components. Producers assemble experiences without duplicating intellectual property. Consumers get personalized, adaptive content without locked-in formats.
For creators
You publish once. Every consumer renders your content on their terms. You don't need to master for every device, every format, every platform. Your source components remain under your control, protected by cryptographic provenance.
For consumers
Every experience is tailored to you. Your surfaces, your preferences, your context. No more downloading files that don't work on your device. No more format incompatibility. Content is rendered for you, in the moment.
