scrolling

:contentReference[oaicite:1]{index=1}

Description

Applies a continuous scrolling motion to the video by shifting the image over time in a single direction.
Unlike scrolling_pro, which allows multi-axis control, this module provides a simple, fixed-direction scroll effect — ideal for lightweight motion or ambient looping.

Purpose

scrolling is designed for creators who want:

a minimal, no-parameter scroll effect,
subtle ambient motion for backgrounds or textures,
lightweight directional drift without configuration,
simple kinetic movement for loops or collage layers,
predictable, consistent scroll behavior.

How It Works

Directional Motion
The video image is translated across the frame at a fixed rate and direction.
Wraparound Behavior
Pixels exiting one side of the frame re-enter from the opposite side, producing an infinite-scroll illusion.
Fixed Parameters
Since the module has no program-specific arguments, its scroll speed and direction are predetermined.
Encoding
Output is encoded using global Videobeaux CRF, codec, and pixel-format settings.

Program Template

videobeaux -P scrolling -i input.mp4 -o output.mp4

Arguments

(No additional program-specific arguments; uses global videobeaux options only.)

Real World Example

videobeaux -P scrolling \
  -i myvideo.mp4 \
  -o scrolling_styled.mp4

Program Output

Technical Notes

Because scroll speed is fixed, this module is ideal for simple kinetic backgrounds.
Looping behavior depends on footage content; pattern-like textures loop more seamlessly.
Best used when a uniform directional drift is desired without fine-tuning.
Works cleanly at any resolution or aspect ratio.

Recommended Usage

Ambient looping textures for projection or VJ systems.
Background drift behind titles, overlays, or motion graphics.
Simple motion injection for collage edits.
Use in batch workflows where consistent, automated scroll is needed.

Quality Tips

Lower CRF produces smoother scrolling with fewer compression artifacts.
Slight pre-blur (e.g., via blur_pix) can reduce visible seams in detailed footage.
Pair with lsd_feedback for evolving drifting effects.
Combine with overexposed_stutter or nostalgic_stutter for stylized motion disruption.
Use convert_dims beforehand if preparing platform-specific scrolling backgrounds.
