Import PowerPoint

Convert a PowerPoint presentation to video

To import a PowerPoint presentation:

1. From the Synthesia homepage, select Import PowerPoint and upload your .pptx file:

   1. Maximum file size: 1GB

   2. Maximum number of slides supported: 150 slides

   3. Supported file format: .pptx

   4. Aspect ratio: 4:3 dimension PowerPoints are converted to 16:9

   5. Important notes on text and fonts:

      1. Fonts must be embedded in your PowerPoint file to display correctly in Synthesia.
      2. In the Auto-add PPTX animations import flow, missing-font replacements are selected automatically, without a font-selection dialog. Font replacement doesn't apply to tables (see Tables). Basic and Starter plans don't support custom font uploads.
      3. SmartArt text is non-editable, and is added as part of the static background.
      4. Lists are imported with a maximum of two levels of indentation, for both numbered and bulleted formats. Deeper levels are not supported

2. If you see How should we convert this?, select Keep my slides, then Continue to open the import options for the editable-slide workflow described below.

   Redesign with Syren opens your deck in Syren to create a dynamic video instead. If Syren isn't available to you, no conversion choice appears and you go straight to the existing import flow. This choice currently appears only for uploads through the Home page's PowerPoint tab.

   Under More options, configure:

   • Auto-populate script: Generates each scene's script from the slide's speaker notes.

     • If a slide has no speaker notes, the script is generated from the slide's text content instead.
     • Note: Requires Convert slides to editable text, shapes, and media to be enabled.

   • Convert slides to editable text, shapes, and media: Imports text boxes, shapes, images, videos, and tables as editable elements. You'll then be able to:

     • Animate all imported elements in Synthesia (animations are not imported from PowerPoint files)
     • Change the size, color, and positioning of shapes
     • Adjust the font styles and positioning of imported text elements.
     • Trim and adjust playback for imported videos to ensure they sync with your script
     • Edit imported table content (see Tables below)

   • Add avatar to each scene: Adds an avatar to every imported scene. If this is off, scenes import without an avatar, and you can add avatars yourself in the editor.

   • Add animations with AI: Automatically adds AI-selected animations to key slide elements, revealing content as the scene changes or the script progresses. These animations are newly added, not imported from your PowerPoint file.

3. Select Import.

4. Edit the video using Synthesia's tools — edit text, add/remove images and videos, add animations and transitions, and more.

5. Click Generate Video to create your video presentation.

Redesign with Syren

Redesign with Syren opens your deck in Syren to create a dynamic video, instead of importing slide by slide.

• Redesign with Syren is available only from Import PowerPoint on the Home screen. Other ways of uploading a PowerPoint file go straight to the slide-by-slide import.
• Some shapes from your deck may not look right in the Syren video. Fix these shapes in Syren after the video builds.
• If you're out of credits, Synthesia shows an upgrade prompt instead.

Layout and text fidelity

The editor preserves your source deck's text formatting and spacing:

• Line height is set per line, so differently sized text on the same slide keeps proportional spacing.
• Paragraph spacing (space before and space after) carries over from the source file.
• Bullet and numbered list characters match the size, color, and text alignment of their associated text.

Tables

Tables import as editable elements: cells and rows resize based on their content, and table text can be edited.

• Tables are imported as motion graphics, so edit their text using the motion graphic text-editing flow rather than as a standard text box.
• Tables share the same editing constraints as other motion graphics: you can edit table text, but you can't regenerate a table's style or layout with a prompt.
• Font replacement doesn't apply to tables.
