Batch review notes, lock preproduction, test a tenfold price rise and pin tool versions. A guide from the Korean producers' 8 November cost warning.

The Korean producers' warning on 8 November points to a practical lesson: in AI production, the number of revision rounds and the price per attempt drive the budget more than the headline cost. This guide turns their points into steps.

## Count attempts, not shots

Our 3 November guide showed that cost per usable clip depends on how many attempts you discard. Kim Kwang-jib's point adds the human side: every re-render is paid for again. Use his example as a rule. Ten notes sent together can cost one re-render, while ten notes sent across ten days can cost ten.

- Collect notes into one review round per sequence.
- Set a limit on rounds before the shot is locked.
- Record each re-render and its reason.

## Lock the preproduction

Kim says weak preproduction can push AI above the 35mm era in cost. Before generating, fix the script, storyboard, character references and style references for a sequence. Treat changing them as a new budget line.

## Test the budget against a price rise

The tenfold stress test is a planning step we added. Take your current price per second, multiply it by ten, and see whether the project still works. Kim's own example turned a token bill of roughly KRW500 million into KRW5 billion, which equals the whole KRW3-5 billion budget of a typical Asian feature, while a far larger Hollywood budget could absorb it. If your plan fails at ten times, either budget a reserve or choose a cheaper path for those shots.

## Lock tool versions per sequence

Lee says tools update weekly and make a year-old shot look dated. Mixing versions inside one scene can break continuity. Choose a model and version per sequence, note it in the prompt log, and change it only at a sequence boundary unless a shot fails.

## Use AI where it is cheapest to be wrong

Kim's hybrid approach puts AI on large crowds and live action on leads' close-ups. Generate wide, forgiving shots, film the shots that audiences judge on faces, and review the split after a test sequence.

## Test delivery early

Lee says streamers check files mechanically and AI output struggles with bitrate and colour grading. Export a short test clip in the delivery format at the start.

## Keep the cheap shots cheap

Match the model to the shot: a lower-cost model for establishing shots, a stronger one for hero shots. Compare cost per usable clip, as in our 3 November piece.

## What to watch

Whether tool makers publish stable price commitments, and whether more productions report their revision counts alongside their budgets.

## RenderBob 3 and this story

RenderBob 3 makes the model a per-clip choice and keeps each clip's references and prompt log with the studio, which is what a revision count, a version lock and a cost comparison depend on.
