Delivery primer: keeping a spec sheet per episode

A spec sheet per episode records, for every clip, the tool, model, resolution, frame rate, shape, length and any mark. It is what lets a later fix be generated to match. From 5 source pages, read 2026-09-25; no maker pays to be listed.

A spec sheet per episode records, for every clip, the tool, model, resolution, frame rate, shape, length and any mark. It is what lets a later fix be generated to match.

Vendors change models and defaults; a clip generated this month at 1080p by default may come out at a different default next month. Recording the figure at the time is the only reliable way to match it.

The sheet on this site is the vendor-level version of the same record.

2The production side of the spec

For a delivery question like “Keeping a spec sheet per episode”, SceneMixer states the following about what it produces:

It is the reference every later segment points at, which is what keeps a character's face and a location consistent across an episode.

SceneMixer, Glossary — “What is a setup image for?” (read 2026-10-13)

Typically 60–120 seconds, always 9:16 vertical, ending on a hook. SceneMixer's episode outlines are generated with that pacing, and setting a project to 9:16 makes every segment vertical (the default is 16:9).
