To make an AI video, pick a format that already works, write a short script, generate the visuals with a text-to-video or image-to-video model, add an AI voice, captions and music, then edit and export in the platform's format (9:16 at 1080x1920 for TikTok, Reels and Shorts). Tools like Revid handle all six steps in one place.
AI visuals can win reach and still lose the audience. In Revid's study of TikToks posted from May 2025 to September 2026, AI-generated videos averaged 1.4M views against 661.4k for real footage, but earned a 3.9% like rate against 7.7%. The gap comes from the inputs (the idea, the hook, the pacing), not from the model, so most of this guide is about getting those right.
How to make an AI video in 6 steps

1. Start from a format that already works
The most common mistake is opening a generator and typing "make a viral video about X". A blank prompt carries no information about what your audience watches, so the output drifts toward a generic average.
Instead, find two or three short videos in your niche that clearly outperformed, and note what they share: the first line, the shot type, the length, the pacing of cuts. That becomes your brief. If you can't name the hook and the structure of your video before you generate anything, you're not ready to generate.
2. Write a script for the ear, then cut it
AI voices sound most natural on short, declarative sentences. Write the way you talk, put the payoff in the first line, and break any sentence that needs a breath in the middle.
Then cut. In Revid's analysis of 176,367 TikToks with 1,000+ likes posted between October 2025 and October 2026, videos with under 40 characters of speech had a 123K median and 20.2% passed 1M views, while videos with speech throughout (300+ characters) had 68K and 11.9%. Silent videos sat at 73K. The sample only holds videos that already reached 1,000+ likes, so this shows what top videos share rather than a cause, but the direction is clear: let the visuals carry the story. The full method is in our study of what makes a TikTok go viral.
Videos with just a few spoken words (a line or two) beat both silent videos and videos that talk the whole way through, which were the most common and the weakest.

If you want to hear how a script reads before you build the video, run it through any text-to-speech engine, for example the setup described in MultitaskAI's text-to-speech settings docs. Rewrite every line that sounds stiff out loud.
Prompt to try
Make a 30-second vertical video on why octopuses have three hearts. Open with the hook "Your heart beats alone. An octopus has three." Use short, declarative narration of only a few lines and let close-up underwater visuals carry the story, with captions and calm ambient music.
3. Choose how to generate the visuals
"AI video" covers five different methods. Pick by what the video needs to show.
| Method | What you give it | Best for | Watch out for |
|---|---|---|---|
| Text-to-video | A written scene description | Original scenes, stories, b-roll | Inconsistent characters across clips |
| Image-to-video | A photo plus a motion prompt | Realistic results, product shots, brand visuals | Motion that drifts away from the photo |
| Talking avatar | A script and a presenter | Explainers, training, UGC-style ads | Stiff expressions on long takes |
| Script with stock or AI images | A script or a link | Faceless explainers, listicles, news recaps | A slideshow look if every scene is static |
| Your footage plus AI | Clips you filmed | Restyles, face or character swaps, b-roll fill | Rights to anything you reuse |
Most video models generate short clips, not whole videos. Google's Veo 3.1, for example, outputs 4, 6 or 8-second clips. A 30-second video is therefore several scenes stitched together, which is why the script and the scene plan matter more than any single generation. For a beginner walkthrough of a first generation, see how to generate a video with AI.
4. Add voice, captions and music
Pick a voice that fits the topic (calm for finance, fast for entertainment) and set the speed slightly faster than you think, since short-form viewers skim. Add burned-in captions: many people watch with the sound off, and captions double as a second hook.
Use music that sits under the voice, not on top of it. If the platform's audio library is limited for your use, generate an original track or use royalty-free music so the video isn't muted or claimed later.
5. Edit for pacing and check for AI artifacts
Watch the video once at full speed on your phone, the way your audience will. Cut any scene that holds after its point is made, and replace any clip with visible artifacts: warped hands, garbled on-screen text, faces that change between shots, or objects that melt during motion.
Regenerate the weak scene instead of the whole video. A timeline editor that lets you swap one clip saves most of your credits and time.
6. Export in the right format and publish
Export vertical 9:16 at 1080x1920 for TikTok, Reels and Shorts, and 16:9 for regular YouTube and most websites. Specs for each platform are in the table further down.
Length matters less than people think: in the same 12-month Revid study, every length bucket from under 15 seconds to 10 minutes had a median between 58K and 76K views. A strong first line beats a perfect duration.
How to make realistic AI videos
Realism comes from three things: a prompt written like a shot list, a camera style people associate with real footage, and sound.
Use this prompt formula for each scene: subject + action + setting + camera + light + mood + sound. One action per clip. Example:
Handheld phone footage, close-up of a barista pouring latte art in a small café, morning window light from the left, shallow depth of field, slight camera shake, natural colors, ambient café noise.
A free AI video prompt generator can turn a rough idea into this kind of structured prompt with camera directions.
More rules that make AI footage pass as real:
- Shoot it like a phone. Ask for handheld, POV or selfie framing instead of sweeping drone shots. In Revid's TikTok study, POV videos had a 107K median against 48K for selfie videos, so POV is the stronger choice when you have a free pick.
- Start from a real photo. Image-to-video keeps lighting, skin and textures grounded in reality far better than text alone.
- Keep characters consistent. Reuse the exact same character description (or the same reference image) in every scene prompt.
- Avoid known failure points. Readable on-screen text, close-up hands doing detailed work and fast crowd motion break most often. Add text in the editor instead of asking the model to render it.
- Add sound to every clip. Silent footage reads as fake. Use a model with native audio or layer ambient sound in the edit.
- Use a natural voice. A cloned version of your own voice, or a voice with slight pauses written into the script, sounds less synthetic than a flat narrator.
Realistic AI content also has to be labeled. TikTok requires creators to label AI-generated content that contains realistic images, audio or video; YouTube requires disclosure through the "AI use" setting in YouTube Studio for realistic scenes that didn't happen; Meta requires its AI disclosure tool for photorealistic video on Instagram and Facebook. TikTok and YouTube both state that the label alone does not reduce a video's distribution.
Realistic prompt to try
Handheld phone footage, close-up of a baker pulling a tray of fresh croissants from an oven in a small bakery at dawn, warm light from the left, shallow depth of field, slight camera shake, ambient kitchen sounds. Hook line: "This is what 4 a.m. smells like." 20 seconds, vertical 9:16, natural colors.
How to recreate a video with AI
To recreate a video you like, don't copy it. Break it into its recipe (hook, shot sequence, timing, tone), then rebuild it with your own words and new visuals.
- Watch the original and write down the first line, each shot and roughly when the cuts happen.
- Name why it worked: the question it opens, the emotion, the payoff.
- Write a new script on your topic that follows the same structure.
- Generate new visuals scene by scene from your shot list.
- Use original or licensed music, not the source audio.
Revid automates this. Its free deep analysis (up to 60 a day) has an AI model watch any video and explain its hook, timed structure and scroll-stopping moment. From there you can remix a viral video into an original one with options such as "Same energy, new script", "Make it about your topic" or "Post the Part 2". Revid keeps the spoken structure and pacing and writes new words, new visuals and an original music direction.
How to make an AI video with Revid
Revid is an AI video platform that turns an idea, a link or a proven viral format into a finished short-form video and publishes it to TikTok, Instagram and YouTube.
- Open the Revid AI video generator and paste an idea, a script or a link, or pick a video from Revid's library of about 2.77 million short-form videos with their engagement data as your starting format.
- Revid writes the script (pulling transcripts of related high-performing TikToks as references) and builds the video scene by scene. You can choose the model per scene: Seedance 2.5, MiniMax Hailuo H3, Wan 3.0 or Google Veo 3.
- Choose a voice (1,000+ voices in 70+ languages) and one of 30 caption styles; music is added for you.
- Fix any scene in the timeline editor, then export at 720p, 1080p or 4K at 30 or 60 fps, or publish and schedule directly to TikTok, Instagram and YouTube.
If you already know the scene you want, the prompt to video tool turns a written description straight into a video. Sign-up is free and new accounts get free credits to try it, no credit card needed; regular video creation then uses the credits of a paid plan, from $39/month for 2,000 credits, and a 30-second video with Pro AI visuals and a voice-over costs about 40 to 80 credits. For a tour of every feature, see our Revid AI guide.
Which AI video tool should you use?
Analysts at Grand View Research and Market.us both expect the category to keep growing, and more brands now make video in-house, as Wistia's brand video creation trends report, covered by Social Media Today, describes. That means dozens of tools. Pick by the job, not the hype:
| Tool | Best for | Starting price | Limits |
|---|---|---|---|
| Revid | Finished TikToks, Reels and Shorts from an idea, link, song or viral reference, with direct publishing | Free sign-up with free trial credits; paid from $39/month | AI generation uses credits; not built for long-form film editing |
| Synthesia | Corporate training and internal videos with polished avatar presenters in 140+ languages | From $29/month; free plan up to 10 minutes a month | Presenter-led, not built for short-form social formats |
| VEED | Editing footage you filmed, auto-subtitles, translation | Roughly $10 to 24/month | AI generation is a clip inside the editor, not a full video |
| Lumen5 | Turning blog posts into simple text-and-stock videos | Check its site | Limited control over visuals |
| Fliki | Voice-first videos with 2,000+ voices in 80+ languages | From $28/month | Stock-based visuals; free plan is watermarked at 720p |
| D-ID | Talking-head videos from a single photo | Check its site | Focused on talking faces |
If you're choosing between an avatar platform and Revid, our Revid vs Synthesia comparison goes through the differences feature by feature. If your main need is cutting your own long recordings into clips, a dedicated clipping tool may fit better.

FAQ
Can I make AI videos for free?
Yes, with limits. Several tools have free plans that are watermarked or capped (Synthesia allows up to 10 minutes a month, Fliki exports at 720p with a watermark). On Revid, sign-up and the viral video library are free, and regular video creation uses paid-plan credits from $39/month.
Is Sora still available for making AI videos?
No. OpenAI closed the Sora app on April 26, 2026 and shut down the Sora 2 API on September 24, 2026. Current alternatives include Seedance, MiniMax Hailuo, Wan and Google's Veo models.
Do I have to label AI-generated videos?
Yes, when the content is realistic. TikTok, YouTube and Meta all require disclosure of photorealistic AI video, and TikTok and YouTube state that the label by itself does not limit reach. Non-realistic content, such as cartoons or AI-written scripts, doesn't need a YouTube disclosure.
Can AI videos make money on YouTube?
Yes, if the final video shows your creative vision and gives educational or entertainment value. YouTube does not monetize mass-produced AI content made from generic templates, stitched-together unrelated AI clips, or AI personas posing as experts on health, legal, financial or political topics.
Can Revid make AI music videos?
Yes. Upload an MP3 or WAV or paste a Suno link into the AI music video generator, and Revid builds a beat-synced video you can edit and publish.
