Description
Subtract for mainContentSeconds and divide end card by video for endCardShare.
Frame intervals distinguish inclusive frame labels from counts between boundaries. Transition sharing and rounding a duration can differ from rounding each endpoint independently.
Subtract for mainContentSeconds and divide end card by video for endCardShare.
When to use this tool
Use Video End Card Duration when you need an explicit frame-boundary or duration-accounting step.
How to use the tool and how it works
- Enter videoSeconds, endCardSeconds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read mainContentSeconds, endCardShare. Use the output convention below.
Require positive videoSeconds and endCardSeconds within the total. Subtract for mainContentSeconds and divide end card by video for endCardShare.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| videoSeconds | Video Seconds | Required. Finite number; strictly above 0. |
| endCardSeconds | End Card Seconds | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| mainContentSeconds | Main Content Seconds | Required. Finite number. |
| endCardShare | End Card Share | Required. Finite number. |

}Limitations and assumptions
- This is a supplied duration split without edit verification, platform rules, viewer attention, advertising performance, or rights assessment.
- 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
Use a consistent frame rate and timecode convention and inspect actual edit boundaries when frame accuracy matters.
