Animated Code Transitions

In this article you'll learn how to create smooth, animated transitions between code steps like this one:

Jumping straight from one code block to another loses your audience. Snipcast animates the diff between steps, so every change is easy to track.

• Highlights What Changed: Lines that are added, removed, or moved are animated automatically, so the eye goes right to the change.
• Smooth, Not Jarring: Transitions ease in and out, keeping the focus on the code instead of a hard cut.
• Zero Manual Keyframing: Write your before and after code, Snipcast computes the transition for you.
• Works at Any Speed: Play transitions live while presenting, or export them as a video at your own pace.

Who is it for

Animated code transitions are perfect for:

• Refactoring Walkthroughs, showing exactly what a change touched, before and after,
• Product Demos & Talks, where a smooth transition feels more polished than a slide swap,
• Teaching Concepts, like showing how a function evolves as new requirements come in.

How to Step-By-Step Guide

You can create your first animated transition within minutes:

1. Open Snipcast, and click on Create New.

2. Write your starting code as Step 1.

3. Select the appropriate programming language on the right panel.

4. Click on the + sign to add Step 2.

5. Update the code in Step 2 to reflect the change you want to show.

6. Switch between Step 1 and 2 to preview the transition.
   Tip: Small, focused changes between steps produce the clearest transitions.

7. Click on Present to animate the transition live, or Export to save it as a video.
