Watch it

Thirty seconds, no sound needed: every line is captioned. A breadboard becomes a board, and then the app reads the real example project and points at what the usual checks do not.

Every cut is on the Product video release. Download a file and upload it to the post: feeds play an uploaded video inline, which they will not do for a link. Each video has two companion files:

  • -cover.jpg: the opening frame, for a platform that asks for a thumbnail;
  • .srt: the captions, for a platform that takes a caption file.

The long cut runs 61.5 seconds; its files say 60s, the slot it is made for.
