NOTES
- Numbers on screen that aren't from a named source are examples (for example the gigabytes-per-hour bars are my arithmetic from YouTube's bitrates).
- Safe-area margins for vertical video are examples only. I did not find official numbers.
- The Shorts help page I read says a maximum resolution of 1080p; some third-party guides say otherwise. The video says so. Check YouTube's live pages before relying on any number.
- Wikipedia is a secondary source; where only Wikipedia was available (history, 29.97, drop-frame, shutter angle, aspect ratio history) the video says "Wikipedia says".
- Facts were checked in October 2026.
- Narration is an AI-generated version of my own voice.
