Product demo video FAQs
How do I make a product demo video with AI?
Start from a prompt, a document, a deck, or a public URL, then add screenshots or a screen recording of your product and let an AI avatar narrate. Describing your idea to Assistant gives you an editable outline of sections and key points before any scenes are generated, and you can set a Dynamic style (shorter scenes, frequent cuts) or a Presentation style (longer, denser scenes). Starting with a prompt, script, or file needs a paid plan. Check out some product demo video examples here.
Is Synthesia's product demo video maker free?
Yes, the product demo video maker is free to try. The Basic plan costs $0 and includes 10 minutes of video and 500 credits every month. You can start from a template, import a PowerPoint, or build from a blank canvas, and dubbing is available too. You can also make your first video with the tool at the top of this page, with no credit card.
Can I record my screen to make a software demo video?
Yes. Install the AI Screen Recorder extension for Chrome or Edge, then capture your full screen, one window, or a single browser tab. Recordings can run up to 60 minutes, though 30 minutes or less makes transcription and editing smoother. Your voiceover is turned into an editable script with filler words removed, and the recording is split into scenes. If you already have an MP4 from another tool, you can upload it from the Record button inside a video, up to 500MB and 30 minutes.
What files and links can I turn into a product demo video?
The video maker at the top of this page accepts PPTX, PDF, DOCX, and TXT files, or a link to a public article or blog post, and rejects pages with over 4,500 words. Inside Synthesia, Assistant accepts .ppt, .pptx, .pdf, .doc, .docx, and .txt files up to 10MB each, plus URLs, and you can combine files, links, and a prompt in one request. To keep your slides as editable scenes instead, import a .pptx of up to 150 slides, and embed your fonts in the file so text displays correctly.
Can I add interactivity to my product demo video?
Yes, you can add interactivity to your product demo video. Turn text or shapes into buttons that open a URL or jump to another scene, so viewers can choose their own path through your product. Buttons and branching menus are available on Pro plans and up, and quizzes are Enterprise only. Interactive videos play in the Synthesia player through a share link, an iframe embed, or a SCORM package, and a downloaded MP4 can’t include them.
Can I update my demo when my product changes?
Yes, and you only redo what changed. Each scene is edited on its own, so you can rewrite the script for one scene, trim or split a recording, or replace a single clip and regenerate. If your interface changed, you will need a new or updated recording for those scenes, but the rest of your video stays as it is.
Can I translate my product demo video?
Yes, in two ways. For a video you made in Synthesia, one-click translation translates the script and on-screen text into 140+ languages and keeps the same avatar and design. For any video file or YouTube link, AI dubbing replaces the spoken audio in 130+ languages, with optional lip sync.
Where can I share or embed my demo video?
Share it with a link, embed it with an iframe, or download it as an MP4. Embed it in tools such as Intercom, HubSpot Knowledge Base articles, Shopify, WordPress, and Userpilot with the integrations in the docs. For YouTube, download your video and upload it yourself in Full HD 1080p. Synthesia doesn’t publish directly to social channels.
How long should a product demo video be?
It depends on the job. A launch announcement can be short, while a full onboarding walkthrough may need more time. Many teams split longer demos into separate videos or add chapters so viewers can jump to the part they need. A Synthesia video can hold up to 150 scenes of up to five minutes each, with a total duration of up to four hours.
What does a product demo video cost with Synthesia?
Starter is $19 a month and Pro is $89 a month, billed monthly, and Enterprise pricing is custom. Plans use credits, and a typical finished video uses about 100 credits per minute. The 10 minutes of video and 500 credits every plan includes are used before any paid credits. See pricing for current plans.
Not just a product demo video maker
Synthesia is an end-to-end AI video platform for creating, localizing, and managing video at scale. Turn a deck into narrated scenes with PowerPoint to video, put a presenter on screen with AI avatars, or capture your product with the AI screen recorder.
Dub finished videos into new languages with AI dubbing, add interactivity on Pro plans and up so viewers choose their own path, and turn your guides into video with PDF to video. One platform, from first script to finished demo.
