How to Create a Professional Video With Synthesia
1. Set Up Your Synthesia Account
Get started by visiting synthesia.io and clicking Get started (no credit card needed). Sign up with your email and create a password, then verify your address if prompted. After logging in, you’ll see your dashboard with options like My Videos, Templates, and Assets — everything you need to begin creating a Video with Synthesia quickly and easily. You can start on the free plan to try things out (it supports up to 3 minutes of video per month and a limited avatar selection). As a bonus, you won’t need any camera or microphone – Synthesia runs in your browser and uses AI avatars and voices based on your typed script. Once logged in, you might also explore adding your company logo or colors in a Brand Kit (if available on your plan) so that all your videos look on-brand from the start.
2. Write an Engaging Marketing Script
Before diving into the editor to create your Video with Synthesia, write a clear and compelling script. Aim for a concise length – marketing videos often work best around 30–90 seconds (roughly 75–150 words). Use a friendly, confident tone that matches your brand personality (e.g. enthusiastic and upbeat for consumer products, or calm and professional for B2B services). Structure your script with a hook at the start to grab attention, a brief explanation of the benefit or solution in the middle, and a strong call-to-action at the end. One helpful framework is FOCA:
– Focus (Hook): Start with a question or bold statement (e.g. “Tired of slow internet?”).
– Outcome: Quickly promise the viewer what they’ll gain.
– Content: Deliver your key message or features in simple terms.
– Action (CTA): Finish with a clear next step (e.g. “Sign up now for a free trial!”).
Keep sentences short and jargon-free. For example, a script might say: “Looking to grow your skills? Our online courses make learning easy in just 10 minutes a day. Join over 10,000 students and start your first free lesson today!” After writing, read your script aloud to check the flow and timing — this ensures it sounds smooth once turned into a Video with Synthesia. Each scene in Synthesia will speak a chunk of this text, so break it up by natural pauses or sentence ends.
Once your script is ready, it’s time to bring it to life — open Synthesia and start creating your first AI video in minutes.
3. Pick the Right Avatar and Voice
In Synthesia, avatars are AI-driven presenters, and selecting the right one is key to producing a polished Video with Synthesia. Choose one that fits your content: think about gender, age, dress style and energy level. For example, a relaxed, casual avatar might suit a lifestyle product, while a more formal, suit-wearing avatar would fit a corporate pitch. Browse the avatar gallery and preview a few voices – you’ll see many languages and tones (cheerful, friendly, calm, etc.). Match the voice tone to your message: an excited, upbeat voice can add energy, while a steady, clear voice lends authority. If your audience is international, pick the appropriate language or accent. Don’t stress about lip-sync; Synthesia automatically syncs the avatar’s mouth to your script.
Tip: consistency matters – using the same avatar (or a small set of similar ones) throughout keeps the video cohesive.
4. Build Your Video with Synthesia
Start a new video project: In your dashboard, click Create Video (or New Video). Give it a title and select a template if you want a head start (there are marketing or product demo templates you can customize), or choose a blank video to build from scratch. Set the aspect ratio (like 16:9 for standard video).
Add your scenes and script: Each video is made of scenes. By default there’s one scene; you can add more as needed. For the first scene, paste the first part of your script into the text box. Then select your avatar and voice for that scene. Repeat for each scene: paste the next lines of your script, and choose the avatar (you can keep the same one or pick a different matching avatar if you want variety). Synthesia will generate the speech and lip-sync automatically for each scene.
The media panel in Synthesia’s editor lets you upload images or pick stock visuals for each scene.
💡 Tip: You can explore dozens of ready-made marketing templates inside Synthesia’s video editor to save time and keep your visuals on brand.
Upload brand assets and visuals: Click the Media button (or Assets) in the top toolbar. Upload your logo and any product photos or branded images. Drag and drop them onto the scene – for example, place a corner logo or an image of your product when building a Video with Synthesia that feels polished and on-brand. From the Library or Environments tabs, you can also pick background images (e.g. an office, outdoors, or abstract gradient) to set the tone. The Create with AI tab can even generate short video clips from a text prompt for b-roll. Adding one clear visual per scene helps illustrate your point without clutter. For instance, if you’re talking about a feature, show a related icon or photo on the side. Stock content from Getty, Pexels, etc. is available directly in the panel.
Add on-screen text: to emphasize key points in your Video with Synthesia, click the Text button in the toolbar. Choose a style (Title, Subtitle, Body text, etc.), then type your caption or bullet list. Format it (font size, color) to match your brand. You can easily create bullet points by typing * then space. For example, you might list three main benefits as bullet text while the avatar speaks. Place the text box so it’s readable but doesn’t cover the avatar’s face.
Add background music: Click the Music toggle on the right side. Browse the music library by genre or mood and preview tracks. Select one and click Add to apply it to your scene. Adjust the volume slider (Synthesia recommends around 10–20% volume) so the music stays in the background. You can copy the same track to all scenes or use different ones per scene. Music adds polish and energy, but keep it subtle.
Transitions and timing: Turn on Scene Transition in each scene’s settings to create smooth fades between scenes. Pick a simple transition style (or apply one to all). Let Synthesia handle most timing: t will match the avatar’s speech to the length of the scene, ensuring your Video with Synthesia flows smoothly. If a scene feels rushed or too long, break the text across more scenes or edit your script.
Preview as you go: Use the Preview button on each scene (and the play button for full video) to check how it looks and sounds. Make sure the avatar is clearly visible, text is legible, and visuals align with the dialogue. Adjust positions and sizes in the canvas as needed.
5. Review and Refine Your Video
Once all scenes are assembled, watch the full video from start to finish. Listen closely and look for any issues: is the avatar’s lip-sync smooth? Does the voice sound natural and the right volume? Check spelling and grammar in your text boxes. Ensure each scene isn’t too busy – if something distracts from the message, simplify it. Ask yourself: “Am I excited or informed by this Video with Synthesia?” Adjust pacing if needed: shortening text slightly can make the avatar speak more clearly.
- Check consistency: Make sure colors, fonts, and logo usage are uniform. All scenes should feel like part of the same presentation.
- Fine-tune wording: If a sentence sounds odd when spoken, edit the text. You can rephrase directly in Synthesia. Sometimes a shorter sentence or a small pause (by splitting into two scenes) improves clarity.
- Get feedback: Share the draft (via Synthesia’s preview link) with a colleague or friend. Fresh eyes can spot things you missed.
- Polish timing: Use the Trim or Split options on video clips or background animations if a scene needs fine-tuning. Ensure the avatar isn’t idle for too long, and that you’re not rushing the voiceover.
- Final preview: When everything looks right, do one more complete preview. Congratulate yourself – it should flow like a real video, even though no camera was used!
6. Export and Download Your Final Video
You’re almost done! First, click the Generate button (usually top-right) to produce your final Video with Synthesia. Give your video a name and description if prompted. (If you want subtitles burned in, toggle captions on before generating.) Synthesia will render the full video in HD. This may take a few minutes depending on length and queue.
Once generation is complete, go to My Videos in the dashboard. Find your video and click the three-dot menu (⋯) on it. Select Download and choose .mp4 to save the video file to your computer (it will be Full HD 1080p by default). You can also download the audio track (.wav) or subtitle files (.srt/.vtt) if you need them separately — perfect if you plan to repurpose your Video with Synthesia across different platforms.
- Note: Free (Basic) accounts cannot download videos. If you’re on a paid plan (Starter, Creator, etc.), downloads are enabled. If you see “Download” greyed out, you’ll need to upgrade or use the video’s share link.
- Share your video: If you can’t download, use the Public Video Page link or embed code to share the video with others. Paid plans allow watermark-free downloads; free videos will have a Synthesia logo overlay.
Now your professional AI video is ready to share with the world. You’ve done the hard work of scripting and design – Synthesia handled all the production with just your text and assets. Play the final file to make sure it meets your expectations, and send it out on your marketing channels. Enjoy your new video!
