Creating AI Videos in Synthesia

📌
Note:
A Synthesia video can contain a maximum of 150 scenes, each up to 5 minutes long, with a total duration of up to 4 hours. The video limit is reached when either condition is met.

There are several ways to start a video in Synthesia:

Start with a prompt

Describe your video and Assistant generates a script and visuals for you.

Start with a template

Choose a pre-built scene layout, then fill in your own script and media.

Import a script

Already have a script written? Use it exactly as written, word-for-word.

Import a file

Turn a document, deck, or notes into a new script and video.

Import a PowerPoint

Convert an existing PowerPoint presentation into a narrated video.

Start from blank

Build your video from an empty canvas, scene by scene.

Creating something else?

Roleplay Sessions

Build an interactive conversation for learners to practice, instead of a scripted video.

AI Dubbing

Translate the voiceover of a video you already have into another language.

📌
Note:
On Free plans, Start with a template, Import a PowerPoint, Start from blank, and AI Dubbing are available. Start with a prompt, Import a script, and Import a file require a paid plan, since they run through Assistant.

Start with a prompt

Assistant turns a prompt into a video script and visuals. See Assistant for how to write a prompt, review the outline, choose a delivery style, and iterate on the result.

Start with a template

Templates provide a consistent scene layout to start your video from. See Templates to browse the library and what each layout provides.

Import a script

Use this when you have a script already written and want Synthesia to use it exactly as written, word-for-word, instead of generating a new one.

See Import a script for the full steps. There's also an older version of this reached from Create ▾ → Video → Import a file, with different new-scene line breaks — see Import a script (Legacy).

📌
Note:
Do not use Import a file for this, even if your script is saved as a Word doc or PDF — uploading a file generates a new script from its content rather than using your text. Paste your script directly instead.

Import a file

Use this to generate a video from source material — a document, deck, or notes. Synthesia reads the file and writes a new script from its content.

See Import a file for the full steps.

📌
Note:
This does not carry over the original text or structure, even if the file already contains a script or a scene-by-scene breakdown. If you want your own wording used exactly as written, see Import a script instead.

Start from blank

Start your video from an empty canvas and build it scene by scene using the editor.
