How to Create Multiple Social Media Sizes in After Effects

Why Multiple Social Formats Create Repetitive Work

Every output version can require a new composition, different dimensions, reframed layers, and another review. Repeating those setup decisions manually makes it harder to keep naming, timing, graphics, and delivery settings consistent.

Common Aspect-Ratio Families

Choose the actual pixel dimensions required by the destination instead of relying on the aspect-ratio label alone.

Manual Workflow with Duplicated Compositions

1. Finish and save the primary composition.
2. Duplicate it for each required format.
3. Name every duplicate clearly by destination or dimensions.
4. Open Composition Settings and enter the target width and height.
5. Reframe layers, text, and graphics for the new canvas.
6. Review each composition before adding it to the Render Queue.

Reframing Text, Graphics, and Important Subjects

A wide layout rarely transfers directly into a vertical frame. Reposition the main subject, check whether text remains inside the visible area, and adjust graphic groups that were designed around the original canvas. Nested source compositions can help preserve the master design while giving each destination composition its own crop and position.

Maintaining Consistency Across Versions

• Use predictable composition names.
• Keep duration and frame rate intentional across outputs.
• Check shared colors, typography, and watermark placement.
• Confirm that every composition starts from the correct master.
• Review every version instead of assuming the same framing works everywhere.

When Manual Resizing Becomes Repetitive

Duplicating and configuring one or two compositions is straightforward. The process becomes repetitive when a delivery includes many destinations or when the same setup must be rebuilt for every campaign.

A Faster Workflow with Social Exporter for After Effects

Social Exporter applies built-in or custom presets to the currently active composition, creates the required compositions, and sends them to the After Effects Render Queue. Custom presets can define a name, icon, width, height, frame rate, and Nest or Duplicate mode.

Individual, All Duplicate, and All Nest modes control how new compositions are structured. You can review the generated compositions and retain control over final format and render settings in After Effects.
