Description
Calculate supplied caption-visible share of creative duration.
Advertising records distinguish nominal reach, impressions, visibility thresholds, disclosure order and content budgets. New unique people are supplied rather than deduplicated, and caption duration alone does not establish accessibility. Code-point truncation can split a grapheme even when it meets a numeric text budget.
Calculate supplied caption-visible share of creative duration.
When to use this tool
Use Ad Creative Caption Duration Share when you already have captionVisibleSeconds, creativeDurationSeconds and need to calculate supplied caption-visible share of creative duration.
How to use the tool and how it works
- Enter captionVisibleSeconds, creativeDurationSeconds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read fraction, remainder. Use the output convention below.
Require creativeDuration>0 and captionVisibleSeconds in [0,creative]; return caption/creative and creative-caption.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| captionVisibleSeconds | Caption Visible Seconds | Required. Finite number; minimum 0. |
| creativeDurationSeconds | Creative Duration Seconds | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| fraction | Fraction | Required. Finite number. |
| remainder | Remainder | Required. Finite number. |

}Limitations and assumptions
- Duration alone does not establish readable captions, timing alignment, accessibility conformance, actual exposure or comprehension.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review actual audience, media, creative and transaction records with the complete measurement and applicable disclosure rules. Verify definitions and rendering before interpreting local counts or flags as effectiveness, billable delivery or compliance.
