What this is about

Two very different situations produce the same picture. In the first, a cinema-format film is shown on a 16:9 screen and the bars are simply the honest way to preserve the composition. In the second, an editor adds bars to 16:9 material to make it look like cinema — a look that works for a trailer and irritates in a training video. What causes real problems is baking bars into a master: a platform that crops or reformats then adds its own, and the picture ends up in a shrinking box.

A term only helps when everyone on set means the same thing by it — so what follows is how it is used, not a dictionary definition.

What runs differently here

In planning terms, that means:

• Never bake bars into a master that other platforms will reformat; deliver the clean image
• As a style choice bars suit trailers and image films, rarely training or explainer content
• Bars in the picture also eat into the area available for titles and safe margins

With TillyGen

Deliverables held per project in TillyGen make clear which version carries bars and which stays clean, so the right file goes to the right platform.

Change one constraint and the consequences travel through the whole plan: affected shots are flagged, the call sheet is regenerated, and nobody keeps working from yesterday's version.
