Student presentation guide
How do I turn a ChatGPT script into a narrated, animated video for class?
Updated by the Vidi team
Plans start at $5 a month.
A script from ChatGPT is a starting point, not a finished presentation. Before it becomes a video, it needs three things: facts you have checked, sentences that sound natural when spoken, and a length that fits your time slot.
After that, the job splits into two parts: the voice and the pictures. You can do both yourself with slides and a microphone, or let a tool generate them. This guide covers how to prepare the script, what makes a class video work, the different ways to build it, and how to do it with Vidi if you want the narration, animation and captions made for you.
How it works
How to do it with Vidi
Paste your checked script
Fact-check and trim the ChatGPT script first. Then paste it into the chat on your Vidi home page, up to 2,000 characters per message (about 300 words), and say how long the video should be. Making a video uses credits. Paid plans make videos up to 5 minutes, and Pro and higher add widescreen 16:9 for a classroom screen.
Approve the proposal and the script
Vidi splits your script into scenes and shows you a proposal before anything is made. Pick the narration language and one of more than 20 looks, such as clay, watercolour or hand-drawn. Read the script scene by scene and fix any wording or facts before you create the video.
Review, fix and download
Watch the finished video with the captions on. If one scene is wrong in an explainer video, change just that scene with a note instead of starting again. Then download the file, play it on the computer you will present from, and keep your fact-check notes ready in case anyone asks.
Get the ChatGPT script ready to be spoken
Start by checking the facts. AI can get things wrong, and that includes a script written with ChatGPT. Compare every claim, number, date and source against your textbook, lecture notes or a source your course accepts. If a fact cannot be checked, cut it.
Next, rewrite for the ear. Use short sentences, one point per sentence, and plain words. Read it aloud and change anything that makes you stumble. Spell out abbreviations the first time you use them.
Then fit it to the time. Read the script aloud at a calm pace and time yourself; that gives you a rough idea of how long the narration will run. If it is too long, cut whole points rather than squeezing words in. Aim for a few clear points instead of rushing through many.
Finally, make sure it still sounds like your work. Add your own example, the part of the topic you found hardest, or a question your class will recognise.
What makes a good class presentation video
Give each scene one idea. Pair one spoken point with one picture that shows it, so viewers are not reading one thing while hearing another.
Use a simple structure. Open with a question your classmates would want answered, walk through a few clear steps, and end with one takeaway sentence you want people to remember. If you have a time limit, plan for slightly under it.
Turn captions on. They let the video work with the sound off and can help classmates follow technical terms.
Match the shape to the screen. If you will play it on a widescreen projector or laptop, choose 16:9 if your tool offers it; vertical 9:16 is made for phones. Check which one your assignment expects.
If you use a generated voice, listen for mispronounced names and technical terms, and rewrite or respell them in the script if they sound wrong. Watch the whole video once from start to finish before you submit, as if you were in the audience.
Other ways to do it, and when they are better
You do not need an AI video tool. One option is to put each point of your script on its own slide and record your own voice over the slides. If your slide software can record narration and export a video, check its help pages for how. This is the better choice if your teacher wants to hear your voice, or if presenting skills are part of the grade.
If you would rather choose every picture yourself, a video editor that can read text aloud is another route. Check what your chosen editor actually offers before you start.
A third option is a template animation tool or an AI script-to-video generator. Vidi is one of these: you paste the script, approve the scenes, and it makes the narration, animation and captions. Whatever you choose, check before you start whether the free version adds a watermark, limits the length or lowers the quality at export, and whether your school already gives you access to a tool.
AI rules, file checks and timing
Read your assignment brief and your course's AI policy before you start. Your script came from ChatGPT, and a tool may also generate the voice and visuals, so there may be two uses of AI to declare. If the rules are unclear, ask your teacher. A short note saying which tools you used and what you checked or changed yourself is a sensible habit.
Check what you are allowed to submit: length limit, file type, and whether you upload a file or play it live. Test the file on the computer or platform you will use, because a video that plays on your phone may not play the same way elsewhere.
Leave time at the end. Generating, exporting and uploading a video can take longer than you expect, and you may need a second attempt after spotting a mistake. Aim to have a finished version a day before it is due.
Limits worth knowing
- AI can get facts wrong, both in your ChatGPT script and in any draft a video tool writes. Vidi does not check the facts in your video, so check every claim yourself before you present.
- Making any Vidi video uses credits. A free account is limited to vertical 9:16 videos of 15 seconds; longer videos need a paid plan, and widescreen 16:9 for a classroom screen needs Pro or higher.
- You can paste up to 2,000 characters (about 300 words) per message into the Vidi chat, so check your script's length before you paste it.
- A generated video is not the same as presenting it yourself. If your grade depends on your own voice or delivery, recording yourself over slides is the better fit. You also need to be 18, or have a parent's or guardian's permission, to create a Vidi account.
Do I need to tell my teacher I used ChatGPT and an AI video tool?
Follow your course's AI policy, and ask your teacher if it is unclear. Even when it is allowed, a brief note saying which tools you used for the script, voice and visuals, and what you checked or rewrote yourself, is a sensible and honest habit.
How long should my presentation video be?
Follow the time limit in your assignment first. Then read your script aloud at a calm pace and time it to get a rough idea of how long the narration will run. If it runs over, cut whole points rather than speeding up. Aim slightly under the limit.
Should I use an AI voice or record my own?
If the assignment assesses your speaking or your teacher wants to hear you, record your own voice over slides. If the video is a visual aid inside a live presentation, a generated voice can work. Either way, listen for mispronounced technical terms and fix them.
Can I make this video with Vidi for free?
Creating a Vidi account is free and needs no credit card, but making any video uses credits. Credits come with a monthly plan, starting with Starter at $5 a month for 5 credits, or a one-off pack from 10 credits for $10. Each video's cost depends on its length, style and engine.
Will the video fit the projector screen in my classroom?
If the screen is widescreen, a 16:9 video will fill it. In Vidi, widescreen is available on Pro and higher plans; free and Starter accounts make vertical 9:16 videos. Whatever tool you use, test the file on the classroom computer before the day you present.
Can the narration be in a language other than English?
Yes. In Vidi the narration can be in 74 languages, including Spanish, French, Hindi, Arabic and Mandarin Chinese. Choose the language on the proposal before you create the video. The Vidi chat itself replies in English.
What if the video has a mistake after it is made?
In a Vidi explainer video you can change a single scene with a note and keep the rest, instead of starting again. If a video fails or you cancel it, the credits reserved for it are returned to your account automatically.
