Count Generator

This generates a countdown or count-up leader traditionally used in film and television before program start.
This generator recreates classic film leader / broadcast countdown visuals, including numbers, timing marks, and optional reference sounds.

Count is a generator, not a filter.
All controls are adjusted in the Properties tab of the generated clip.

What a count leader is (historical context)

Before digital playback, films and tapes required manual cueing and synchronization.
Countdown leaders were used to:

• Signal that a program was about to start
• Give projectionists and broadcasters time to cue playback
• Synchronize sound and picture
• Provide a reference point (“start at zero”)

These leaders were commonly seen:

• At the beginning of cinema reels
• Before television programs
• On broadcast tapes and test transmissions

The rotating clock, quadrant background, and large numbers are all part of this legacy.

Generator behavior

• Produces an animated video
• Duration is explicitly defined by the user
• Animation and numbers depend on style and direction
• Must be evaluated during playback to understand timing

Parameters

Direction

Defines whether the count decrements or increments.

• Down
  Classic countdown toward zero.

• Up
  Count-up / chronometer behavior.

Style

Controls how time is represented visually.

Seconds

Displays only whole seconds.

• Does not display the starting value
• Displays 0 at the end
• Example (Duration = 10 s, Down):
  9 → 8 → … → 1 → 0

Seconds +1

Displays the starting second value.

• Displays the starting number
• Does not display 0 at the end
• The animated needle continues through the final second

Example (Duration = 10 s, Down):
10 → 9 → … → 1 (no visible 0)

Frames

Displays frame numbers based on the project’s frame rate.

• Uses the project FPS
• The counter spans the entire duration of the generated clip, starting from the total number of frames (countdown) or from zero (count-up).
• Useful for frame-accurate timing

Timecode

Displays time in HH:MM:SS:FF format.

• FF = frames
• Matches standard video timecode representation

Clock

Displays time in HH:MM:SS format.

• No frame display
• Acts as a visual timer

Sound

Controls reference audio cues.

2-Pop

Plays a short beep exactly one second before the end.

• Classic synchronization cue
• Widely used in film and broadcast workflows

Silent

No sound.

Frame 0

Plays a short beep every second.

• Useful as a rhythmic timing reference

Background (Clock | None)

Controls the visual style of the background.

• Clock
  Animated film-leader style background with rotating sweep and quadrant divisions.

• None
  Plain background with numbers only.

Drop Frame (checkbox)

Controls whether drop-frame timecode is used.

• Relevant only when using Style > Timecode
• Applies to NTSC-derived frame rates
• Does not affect visual countdown styles

Duration (time input)

Sets the total length of the generated count.

• Format: HH:MM:SS.mmm
• Determines how many seconds, frames, or units are shown

Visual characteristics

• Large, high-contrast numbers
• Rotating clock-style sweep (when enabled)
• Quadrant background reminiscent of film leaders
• Designed for readability and timing clarity

Contemporary use

Today, count leaders are used primarily as historical or stylistic elements, rather than technical necessities.

Common modern uses include:

• Intro or outro sequences
• Documentary or archival context
• Retro or broadcast-era aesthetics
• Clear visual timing before content starts
• Creative transitions referencing cinema or television history

Use with other filters

Count generators are often combined with filters for creative or practical purposes:

• Blur
  Soften the image for stylized transitions.

• Grain / Noise
  Enhance film-era authenticity.

• Color grading
  Convert to aged tones or colorize.

• Blend modes
  Overlay the count on footage as a transitional element.

• Fade In / Fade Out
  Smooth entry into the main content.

Usage notes and tips

• Choose Seconds +1 if you want the starting value to be visible.
• Use 2-Pop only when an audio reference is meaningful.
• Match Duration carefully to your intended cue point.
• Preview playback to verify timing behavior.

Limitations

• Not intended for modern synchronization workflows
• Visual behavior depends on selected style
• No per-frame visual customization
• Purely representational, not functional timing control
