You can type or paste your text outline into our explainer video generator. The tool processes your sentence to create a narrated video with subtitles and music.
Turning a text outline into a narrated explainer video requires condensing your main points into a clear format. Our tool is built specifically to take one sentence and turn it into a complete video that includes voice narration, on-screen subtitles, and background music. If you have a longer text outline, the process starts with refining that outline down to its core message.
What do I need to prepare before generating a video?
Before you make yours, you need to review your text outline carefully. Because the generator uses exactly one sentence to build the entire video, you must condense your outline. A standard text outline usually contains a main topic, a few supporting points, and a conclusion. To prepare this for the generator, you need to write a single, well-structured sentence that covers the sequence of events or the logical argument you want to present.
Read through your outline and identify the subject, the problem, and the solution. For example, if your outline is about a new software tool, your single sentence should state what the tool does, who it helps, and how it works. You do not need to prepare separate audio files, subtitle files, or music tracks. The generator provides the narration, the text for the subtitles, and the music automatically based on the sentence you provide.
When writing your text outline, you must also consider the language of your audience. Our explainer video generator supports two languages: English (en) and Chinese (zh). If your text outline is in English, you will write your single sentence in English. The tool will generate English narration and English subtitles. If your target audience speaks Chinese, you must write your single sentence in Chinese (zh). The tool will then produce Chinese narration and display Chinese characters in the subtitles. You cannot mix the languages in a single sentence if you want accurate narration and subtitles. Choose either English or Chinese before you submit your text to the generator.
If you are unsure about the length or pacing of your message, you can read our guide on how long should an explainer video be. This helps you understand how the length of your text translates into spoken narration. You can also review Opus 5.5 Video Prompts to see examples of briefs that work well. Preparation is entirely about the text; the visual and audio elements are handled by the tool.
How do I use the explainer video generator?
The process of making the video takes place entirely on our website. You do not need to install any software on your computer. Here is the step-by-step method to turn your sentence into a completed video.
First, navigate to the AI Explainer Video Generator. You will see a text input area ready for your input.
Second, take the single sentence you prepared from your text outline and type or paste it into the text box. Check your spelling and grammar, as the tool will read and interpret exactly what you provide. The words you type will appear directly on the screen as subtitles.
Third, submit the sentence. The generator will process the text. During this step, the system creates the voice narration, times the subtitles to match the spoken words, and adds background music to the audio track.
Fourth, review the final video. The output will be a narrated explainer video complete with the music and subtitles. If you need to review the underlying technology, you can read about the Claude Video Generator and the Opus 5.5 Video Generator.
If you are generating videos and need to process a payment, you will use FloatPass. All payments on the Explainer Video Generator site are handled exclusively through FloatPass. You do not need to set up alternative payment processors. When prompted to pay, the system will direct you through the FloatPass integration. You can review the pricing page to understand when a payment is required for turning your text outline into a narrated explainer video. If you encounter any issues with the FloatPass payment process, you can reach out to support by sending an email to contact@explainervideogenerator.com.
What are the common mistakes to avoid when writing an outline?
When you turn a text outline into one sentence, it is easy to make structural errors that affect the final video. Avoiding these mistakes ensures the narration sounds natural and the subtitles are easy to read.
Do not use overly complex punctuation. Semicolons, dashes, and parentheses can confuse the pacing of the narration. Stick to commas to separate clauses. The voice synthesis relies on standard punctuation to insert pauses, and unusual punctuation can make the spoken audio sound disjointed.
Do not cram too many distinct topics into one sentence. If your original text outline covers five different subjects, pick the most important one. The generator creates a focused explainer video based on the sentence provided. If the sentence lacks focus, the video will jump between ideas too quickly. You are better off making multiple videos for multiple ideas rather than crowding one sentence.
Avoid vague language. Use concrete nouns and active verbs. The generator relies on your words to determine the tone and flow of the explainer video. Clear words result in clear narration and precise subtitles. If you find that your videos are looking too similar to one another, you can read our article explaining why every Opus 5.5 showreel looks the same to learn how to brief one that looks different.

How do narration, subtitles, and music work together?
When you provide your one sentence, the tool generates three distinct audio-visual elements simultaneously.
The narration is the core of the explainer video. The tool reads your sentence and synthesizes a voice to speak the words aloud. The pacing of the voice dictates the length of the video. The narration drives the timing of the entire project, ensuring that the video lasts exactly as long as it takes to read the sentence.
The subtitles are generated directly from the words in your sentence. They appear on the screen in sync with the narration. This ensures that viewers who watch the video without sound can still read the exact message derived from your original text outline. The text you type is the text that appears, word for word.
The music is added as a background layer beneath the narration. It plays throughout the duration of the video, matching the length of the spoken sentence. You do not need to edit the audio tracks together; the tool mixes the narration and the music automatically so that the voice remains clear over the instruments. The combination of these three elements provides a complete explainer video without requiring manual video editing.
Where else do people look for video generation?
While our tool turns one sentence into a narrated explainer video with subtitles and music, people also look at other websites for video generation. Some of the other places people search for these tools include pexo.ai, canva.com, golpoai.com, pictory.ai, capcut.com, and heygen.com. We do not provide details on how those platforms operate, but they are common destinations for users researching video creation methods and comparing different approaches to making explainer videos.
What other types of explainer videos can I make?
Depending on the subject of your text outline, you might want a specific style of explainer video. The single sentence you provide can be tailored to fit different formats based on your needs.
If your outline is about teaching a concept or explaining a theory, you might read about our AI Whiteboard Explainer Video Maker. Whiteboard videos are traditionally used for educational content and breaking down complex ideas into simple drawings.
If your outline details a new item coming to the market, you can look at the AI Product Launch Video Maker. This format is suited for sentences that highlight a specific problem and introduce a new product as the solution to that problem.
If your outline contains statistics, numbers, or trends, you might be interested in the Animated Data Story Video Maker. This is useful when your single sentence focuses on explaining data points or research findings to an audience.
You can also read more about the underlying technology in our blog post detailing how Opus 5.5 videos are made and explore the differences in production methods by reading about code-drawn video vs AI video models.
