Hand-Drawn Annotation Callouts: 24 Animated Marker Strokes

Twenty-four hand-drawn marker annotations for tutorials, explainers, product demos, reaction videos and social posts. Each one draws itself on like a pen, holds, then draws off, on a transparent background.

The 24 callouts

Circle, scribble circle, rough box, underline, double underline, wavy underline, swoosh, straight arrow, curved arrow, loop arrow, S-curve arrow, elbow arrow, double-headed arrow, checkmark, cross, strikethrough, brackets, star, burst, sparkles, heart, spiral, highlighter swipe and speech bubble.

What you get

• Apple ProRes 4444 with alpha at 1920 × 1080 and natively drawn 3840 × 2160
• Colour (signal red #E5432D, highlighter in marker yellow) and White-tintable versions of every callout
• WebM with alpha (VP9) at 1080p for web pages
• index.csv with timing and alpha checks

Timing

All 24 are 75 frames at 30 fps (2.5 s): draw-on in frames 0 to 18, hold 18 to 54 (identical frames, so freeze one to hold as long as you need), draw-off 54 to 72, and empty at the start and end. Multi-stroke callouts draw their strokes in pen order.

Style

Rounded marker strokes with slight pressure taper and a gentle hand wobble, anti-aliased from a 3x to 4x supersampled canvas. Each element sits near the centre of a full frame, ready to scale and position over your subject.

How to use

Place the MOV above your footage in Premiere Pro, Final Cut Pro, DaVinci Resolve or After Effects (straight alpha). Recolour the white versions with Tint or Fill. For the web, use the WebM in Chrome, Edge or Firefox.

Drawn procedurally in Python by AssetLoom. No AI generation and no third-party brushes or fonts.
