Video Duration

What is video duration?

Video duration defines the target length of your final video.

In ReelBot, duration is not a cosmetic setting — it is a structural constraint that influences:

  • script length
  • voice pacing
  • caption density
  • visual sequencing

Duration should be decided early and changed deliberately.


Available duration options

ReelBot currently supports the following durations:

  • 15 seconds
  • 30 seconds
  • 45 seconds
  • 60 seconds

These options are optimized for short-form platforms and predictable pacing.


What duration affects

Duration directly controls:

Script length

  • character limits are enforced based on duration
  • longer durations allow more content
  • shorter durations force concision

Scripts are generated to fit, not overflow.


Voice pacing

  • voiceover generation respects the selected duration
  • speech rhythm is adjusted automatically
  • captions and visuals follow voice timing

Duration defines the tempo of delivery.


Caption behavior

  • longer durations allow more readable pacing
  • shorter durations increase caption density

Caption timing remains accurate via speech marks, but pacing originates from duration.


Visual sequencing

  • B-roll is trimmed or looped to match voice length
  • cinematic videos adapt visuals to duration
  • no manual timeline editing is required

Duration anchors the entire composition.


When duration is applied

Duration:

  • applies immediately when selected
  • persists across drafts
  • is included in templates
  • is restored when editing projects

It remains active until explicitly changed.


Changing duration safely

Changing duration after content has been generated can impact downstream steps.

If you change duration after:

  • topic generation → script & voice must be regenerated
  • script generation → script & voice must be regenerated
  • voice generation → voice must be regenerated

ReelBot will:

  • show a warning dialog
  • list affected steps
  • require confirmation before clearing anything

No work is lost silently.


Duration and regeneration

Duration changes are treated as structural changes.

This means:

  • regeneration is required to maintain pacing integrity
  • old voice timing cannot be reused
  • captions must realign to new pacing

This protects output quality.


Duration and templates

Duration is stored in Templates.

Using a template:

  • preselects duration
  • enforces consistent pacing across batches
  • avoids repeated decisions

Templates are the best way to standardize duration.


Choosing the right duration

General guidance:

  • 15s → hooks, quotes, fast insights
  • 30s → explanations, storytelling
  • 45s → deeper educational content
  • 60s → structured tutorials or narratives

Choose duration based on message, not platform alone.


Common mistakes to avoid

  • changing duration late in the flow
  • using visuals to compensate for rushed scripts
  • forcing long messages into short durations
  • switching durations mid-batch

Most pacing problems start with duration choice.


Best practices

For consistent results:

  • decide duration before generating content
  • keep one duration per batch
  • save winning durations as templates
  • regenerate upstream when changing duration

Discipline beats experimentation at scale.


The CreatorOps perspective

In CreatorOps, duration defines system boundaries.

By fixing duration early:

  • scripts become predictable
  • voice pacing stabilizes
  • regeneration becomes safe
  • batching becomes scalable

ReelBot treats duration as infrastructure — not preference.


  • Script Generation
  • Voiceover Generation
  • Regeneration & Safe Iteration
  • Templates

Choose duration intentionally — everything else follows.
