In the tested workflow, though, the outputs stayed landscape rather than vertical and final download was blocked behind an upgrade, so it was more usable for in-browser review and corporate-style promo work than for immediate short-form ad export. ## Demo Recording [Video: Synthesia demo recording](https://d3epheqghktydj.cloudfront.net/synthesia-synthesia-demo-video-c3b66994a995.mp4) *Video — Screen recording of the tested Synthesia workflow, including script input, avatar selection, generation, and the download/translate menus.* ## Feature-by-Feature Breakdown ### Script-to-Avatar Video Generation **Verdict:** Worked across all three scripts, but the tested output format was not vertical UGC-ready. Synthesia took supplied product scripts and produced finished AI-avatar videos for the tested FutureSmart AI, Nike Pegasus 41, and Duolingo inputs, including spoken narration and successful completion inside the platform. **Input:** ``` FutureSmart AI script: "I've been using FutureSmart AI to discover and compare AI tools in one place. It helps me find the right tool faster with real use cases, rankings, and detailed comparisons. If you regularly use AI tools for work, it's definitely worth checking out." ``` **Output:** > **Video** **Input:** ``` Nike Pegasus 41 script: "I've been wearing the Nike Pegasus 41 for my daily runs, and they've been incredibly comfortable from day one. They're lightweight, well-cushioned, and great for everyday training. If you're looking for dependable running shoes, they're definitely worth considering." ``` **Output:** > **Video** **Input:** ``` Duolingo script: "I've been using Duolingo for a few minutes every day, and it's made language learning simple and fun. The short lessons are easy to follow, and the daily practice keeps me motivated. If you're planning to learn a new language, give Duolingo a try." ``` **Output:** > **Video** **Bottom line:** Reliable generation across three normal promo scripts, but the tested outputs were landscape 16–17 second videos rather than short-form vertical ads. ### Avatar Library and Presenter Selection **Verdict:** Presenter selection was available through a browsable avatar library. The avatar picker provided a searchable presenter library with filters like All Avatars, My Avatars, Shared with me, Recent, Brand kit, and Custom Avatars, along with presenter thumbnails for choosing a presenter. **Input:** ``` Open the avatar picker to review available presenters before generating the video. ``` **Output:** > **Image** **Bottom line:** The presenter library is easy to browse, but this report did not verify separate voice-library breadth or an avatar swap inside a finished ad. ### In-Editor Preview and Playback **Verdict:** Previewing worked inside the workspace. Synthesia let the tester review generated videos inside the workspace before export, so the result could be inspected without leaving the editor. **Input:** ``` Review the generated video inside Synthesia's in-editor preview. ``` **Output:** > **Image** **Bottom line:** Previewing is available and worked as expected, but the report did not test deeper edits or refinement beyond review. ### Export and Translation Controls **Verdict:** Export and translation actions were visible, but gated on the tested account. The version menu exposed download options for MP4 and caption files plus a Translate action, though the tested account showed upgrade gating for download and translation. **Input:** ``` Open the Download submenu on a generated video. ``` **Output:** > **Image** **Input:** ``` Open the Translate option from the same generated-video version menu. ``` **Output:** > **Image** **Bottom line:** The product surfaces export and language workflows, but the tested plan could not complete them. ## Is It Right For You? **Use it if** - You need a straightforward script-in, avatar-out workflow for polished promo videos. - You are comfortable reviewing output inside the web app before export. - You can work with a workflow that may gate download or translation behind an upgrade. **Skip it if** - You need guaranteed vertical 9:16 short-form ads. - You need to download the final MP4 on the tested plan. - You need a highly creator-style or emotionally expressive ad read. ## Classification - **Category:** video-generator - **Subcategory:** avatar-video-generator - **Type:** video ## Frequently Asked Questions **Q: Can Synthesia turn a pasted script into an AI avatar video?** Yes.
