Web Capture — Playwright Website Scroll B-Roll
Presets
Two presets cover 99% of web scroll b-roll:
| Flag | Resolution | Target Duration | Use For |
|---|---|---|---|
--short-form |
1080×1080 (square) | 6.0s hard cap | PIP inside 9:16 Shorts/Reels/TikTok |
--long-form |
1920×1080 (landscape) | 12.0s hard cap | YouTube long-form, VSL, landscape overlays |
Both presets:
- Default 1.2x playback speed
- Auto-compute scroll speed so full page fits in target window
- Trim 2s of leading load frames (vs default 1s)
- Hard-cap final MP4 via ffmpeg
-tfor exact output duration
Override any preset value by also passing the underlying flag (e.g. --short-form --target-duration 8).
