Practical media education with visible limits.

Who we are

We are a group of media professionals. Between us we have worked in cinema, broadcast and radio through a long run of continuous change. We watched film give way to digital acquisition, tape libraries move to file-based storage, analogue consoles become software, and distribution move from scheduled transmission to streams and feeds. Every one of those changes arrived with a promise of simplicity. Every one replaced a settled way of working with a new set of problems.

This site exists so the lessons outlast the tools. We learned most of them in edit suites, control rooms and machine rooms, where nobody wrote them down. Formats change and software changes, and the reasoning underneath stays steady: why a mix holds up on bad speakers, why a delivery spec exists, why an accessible publish reaches more people. We write the reasoning down here, we build free tools you run in your browser, and we give the same attention to where media goes next as to where it came from.

What we are building

The property is evolving from a broad creator library into an independent media utility. The focus is on useful answers that can be tested, cited, taught, and improved: loudness and delivery, accessibility QA, provenance and AI disclosure, podcast operations, and practical production workflows.

Editorial standard

• Primary standards and platform guidance are linked where they matter.
• Calculations disclose their method, supported scope, and known limits.
• Automated checks are separated from work that requires human judgment.
• Affiliate links and commercial relationships are disclosed.
• Material changes should carry an updated review date and changelog note.

Corrections

Send a factual, accessibility, standards, or privacy correction to hello@infinitecreation.io. Include the page URL, the claim or behavior in question, and a primary source or reproducible example when possible. Verified material corrections should be made promptly and recorded in the relevant page history.

Scope labels

Pages and tools use four confidence labels: Reference, Estimated, Validated, and Experimental. Compatibility with a standard or platform is not an endorsement by that organization.

How the pages are checked

The claim on this page that calculations disclose their method is worth making concrete, because it is the part a reader can test. Every worked example table on a calculator page is produced by running that page's own arithmetic, not by typing numbers in by hand. If the table and the tool disagreed, one of them would be wrong and nobody would know which. Doing it this way found a real error: the depth of field calculator was dividing a circle of confusion that was already in millimetres by 1500 instead of 1000, which overstated hyperfocal distance by half and understated depth of field by about a third on every sensor size. It had been live and wrong. The fix and the explanation are both in the changelog, dated.

Every page that states a price carries the date the price was checked, and a figure that nobody has verified carries no date at all rather than a comforting one. Roughly ninety of the money figures on this site are editorial estimates, ranges for a category rather than a price for a product, and those are labelled Estimated and never stamped as checked. Confusing the two would be the easiest way to look more authoritative than the evidence allows.

Where the sources are

All 110 biographical profiles in the broadcast pioneers section carry a Sources section you can see on the page, rather than a bibliography filed somewhere else. Of those, 89 link a document that was fetched and read before it was cited: a patent, a journal paper checked against the publisher's own record, a library scan, a museum catalogue entry. The remaining 21 carry a different kind of section, one that names the record which would settle the claim and says why it could not be reached. Charles Cros is the clearest case. The accounts of when he deposited his sealed paper with the Academy contradict each other, some saying 30 April 1877 and some 18 October, so that page names the contradiction instead of picking a side.

Reading the records rather than the received story changed several pages. The foundational patent on the active pixel sensor names three inventors where this site had credited one. The first digital camera patent lists Gareth A. Lloyd ahead of Steven Sasson. The Bell Labs switching patent that made Erna Hoover's reputation names Barry J. Eckhart alongside her. Each of those pages was corrected and each correction is in the changelog.

Checking also stops things being published. A patent widely described online as Radia Perlman's spanning tree patent turns out to be a wide area broadcast patent with two co-inventors, so it is not cited here and her 1985 paper is cited instead. A patent regularly offered as the prior art that stopped Walter Bruch patenting PAL alternates phase by field rather than by line, which does not support the claim, so that claim does not appear.

Accessibility and what we get wrong

Pages are audited against WCAG 2.2 at level AA, both by reading the markup and by running an automated check in a real browser, because some failures only exist once a page is rendered. Contrast is the obvious one. The audits are re-run whenever content changes rather than once at launch.

The changelog is not a release-notes formality. It is where errors go when they are found, including errors that were live for a long time and errors nobody had reported. A site that never publishes a correction is not a site that never had one.
