Facts checked October 5, 2026. If your Synthesia plan includes API access (Synthesia lists it on Pro and Enterprise), connect with an API key; otherwise download the MP4 and upload it. Either way, Mindstamp plays its own copy of the file and records each learner’s answers and score. ## Pick the route that your Synthesia plan allows | Option | Where in Synthesia | What stays in Synthesia | What Mindstamp adds | | --- | --- | --- | --- | | Connected app (API key) | An API key from your Synthesia account. Synthesia lists API access on its Pro and Enterprise plans. | The project and the original render. The copy comes without the Synthesia captions. | Questions and branching, plus a transcript made from the copy. | | Synthesia share link | The address of a Synthesia share page, pasted into Link. | Everything. | Nothing. A share page is a web page, so Mindstamp shows “Not a video file”. | | Upload the MP4 | Download the video in Synthesia, then upload it. Basic and trial accounts cannot download. | Synthesia keeps the original.

In Synthesia, turn on **Video Sharing**, as Synthesia’s Mindstamp guide describes. 2. Create a Synthesia API key and copy it. 3. In Mindstamp, select **New video**, then **Synthesia** under **Connected apps**. 4. Paste the key into **Synthesia API Key** and select **Submit**. Mindstamp saves one key for the whole organization. 5. Select the card of the video you want. Mindstamp shows a processing screen while it copies the file. [All video sources](https://mindstamp.com/help/what-kind-of-videos-can-i-use-in-mindstamp) ### Add questions and share with learners 1. In the editor, add a question where the avatar finishes each topic. 2. Mark the correct answer on every question that counts toward the learner’s score. 3. Add a button or a branch where the script offers a choice. 4. Publish the video, then copy its link from the **Share** page. 5. For an LMS, select **Download SCORM package**. This needs a Mindstamp Core plan or higher. ## Synthesia quizzes are on the Enterprise plan only ### Synthesia interactivity - Buttons and branching on Pro and Enterprise. Only text and shape elements can be clickable. - Quizzes with single or multiple answers, a results screen, and a pass mark, on Enterprise. - Quiz analytics by learner on Enterprise. Names need Record Learner Identity in SCORM, or SSO on the share page. - Plays on the Synthesia share page, embed, and SCORM. You cannot download an interactive video as MP4. ### What Mindstamp adds - Questions, buttons, hotspots, and branching for a video from Starter, Pro, or Enterprise. - Learner names from lead capture, without Record Learner Identity or SSO. - Quiz scores by learner without a Synthesia Enterprise plan. - A SCORM package on Mindstamp Core and higher. ## Check these before you publish ### This API key was rejected Mindstamp shows this when Synthesia refuses the key, and also when the key works but the list is empty. Check the key, and check that it belongs to an account with videos. ### A video is not in the list Mindstamp makes one request for your Synthesia video list and does not page through it, so a long list is likely cut short. Open the source again after a render finishes. If the video still does not show, download the MP4 and upload it. ### A Synthesia edit does not reach learners Mindstamp plays the copy it made at import. Render the new version, then use Replace source video on the Mindstamp video. Interactions and the share link stay. ## Synthesia interactive video FAQ ### How do I make Synthesia videos interactive? Synthesia has its own interactivity: buttons and branching on Pro or Enterprise, and quizzes on Enterprise. For Mindstamp, connect Synthesia with an API key on the **New video** page, or upload a downloaded MP4. Then add questions and branching in the editor, and Mindstamp records each learner’s answers. ### Which Synthesia plan works with Mindstamp? The Mindstamp connection uses a Synthesia API key. Synthesia lists API access on its Pro and Enterprise plans, so on other plans the connection likely fails. Then download the MP4 and upload it. Synthesia says Basic and trial accounts cannot download, so this route needs Starter or higher. The Synthesia source itself has no Mindstamp plan gate. ### Does Synthesia list Mindstamp as an integration? Yes. Synthesia’s docs have a Mindstamp setup page, and its integrations directory lists Mindstamp under Interactive & Engagement Video Tools. ### Does Synthesia still record views and quiz results? No, not for the Mindstamp copy. Synthesia keeps the original video and the project, and its quiz analytics cover videos published through Synthesia. Mindstamp streams its own copy, so views and answers on the interactive version go to Mindstamp reports. Mindstamp sends nothing back to Synthesia. ### When should I use Synthesia’s own interactivity instead? Use it when the course lives in Synthesia: buttons and branching come with Pro and Enterprise, and quizzes with a pass mark come with Enterprise. Mindstamp fits when you need questions on a Starter or Pro video, or learner names without SSO or Record Learner Identity. ### What happens when I re-render the video in Synthesia? Mindstamp copied the file at import, so its video does not change. Open the Mindstamp video, go to **More**, select **Replace source video**, and add the new render. Your questions and branches stay on the video, and learners keep the same link. The old transcript moves to the new file, so if the script changed, delete it and create a new one.
