Why can a 15-second TVC require more than 15 seconds of video generation?

Write two duration totals

Consider a fictional 15-second desk-lamp edit with nine approved shots. The current CartVisual TVC prompt compiler requests a five-second native source clip for each shot. The arithmetic is 9 × 5 = 45 seconds of planned source footage, although the accepted final timeline totals 15 seconds. This does not mean 45 seconds of continuous finished video.

The plan supports 9, 16 or 25 shots; read the saved plan’s actual count. These are duration calculations, not prices or successful-generation records. The current quote calculates the film quantity from compiled shots and exposes generated duration separately from final duration. Recheck if the implementation, approved plan or model binding changes. A video provider’s unrelated duration menu does not alter this saved TVC calculation.

For the fictional nine-shot example, one additional five-second retake adds five planned generation seconds: 45 + 5 = 50, while the intended edit can remain 15 seconds. Record the actual successful jobs, failed/uncertain jobs and charge rules separately; the arithmetic does not decide whether a failed request is billable or refunded. The current assembly uses the configured prefix of each source clip, not every generated second.

Separate the chargeable stages

This table uses the fictional nine-shot case; a 16- or 25-shot plan changes the source row. The four sheets are alternatives for one film, not four included films. Keep image generation and video generation on separate budget lines. Adding narration, licensed music or an external editor is also a separate production decision. The example quantities describe a workflow; current prices come from the application quote.

Budget for a decision, not unlimited attempts

Set an initial approval budget and a repair allowance before submitting. For the lamp, reserve the allowance for an incorrect switch interaction rather than spending it on a fifth attractive storyboard. If the important action cannot be shown faithfully, stop and capture real footage. More attempts do not establish product performance or guarantee a usable result.

Use the downloadable TVC review ledger to record generated seconds and accepted edit seconds separately. This is a manual planning aid. It does not read your wallet or submit a job.

Reconcile the completed film

After completion, list the actual successful source clips, failed jobs and any approved retakes. Match charges to the task record and current credit rules rather than this fictional arithmetic. Watch the delivered film at normal speed and inspect the source clips separately. A successful assembly only establishes that the files were combined; it does not approve the advertised product claims.
