How Do You Turn a Blog Post Into a Video With AI?
Turn one blog post into a 60-second video: choose the idea, rewrite for the ear, generate scene-by-scene B-roll, add a voiceover and captions, then resize and embed.
A blog post becomes a video when you stop trying to cover the whole article and pick the one idea worth 60 seconds. Take the single most useful point, rewrite it as spoken sentences, generate one B-roll shot per sentence, add a voiceover and captions, then export the aspect ratio the destination needs. The whole job can be done with one tool for the script, one for the B-roll and one for the voice, and the first 10 credits are free.

Pick the 60 seconds worth filming
A post is written to be skimmable, with headings, caveats and side notes. A video is linear: the viewer cannot jump back, so every sentence has to earn the next one. That is why the first job is subtraction, not adaptation.
Read the post and look for the passage you would send to a friend. It is usually a single claim with a concrete example, or a mistake with a fix. Write that passage down in one line. If you cannot, the post has several ideas and you should make several short videos rather than one crowded one.
- The strongest claim. The one sentence a reader would quote.
- The sharpest example. A before-and-after, a price, a specific mistake.
- The obvious question. The thing a reader asks in the comments, answered directly.
One blog post can yield a small series this way. Three videos from three sections usually reach more people than one video that summarizes all three badly. If the post already has a script-like structure, the AI script writer can compress a section into a first draft.
Rewrite for the ear
Spoken sentences are shorter than written ones. Cut subordinate clauses, replace semicolons with full stops and read the draft aloud. If you run out of breath, the sentence is too long. If you stumble, a viewer will too.
Keep the specifics. A video that says "save time" is wallpaper; a video that says "cut the clip at the pause, not mid-word" gives the viewer something to do. Numbers, names and concrete actions survive the move from page to camera better than abstractions do.
Write the opening line last. The first sentence has one job: make the viewer stay for the second. A useful pattern is to state the problem in the viewer's words, then promise the fix in the next line. Avoid introducing yourself first; the viewer came for the answer, not the biography.
Generate B-roll scene by scene
One shot per sentence is a reliable rhythm for a 60-second video. That gives you roughly eight to twelve shots, each four to eight seconds, which is the range most models handle comfortably. Write a shot list with one action per row, then generate each shot separately.
| Script beat | Shot to generate | Why it works |
|---|---|---|
| “Most clips are cut too late” | A hand trimming a clip on a timeline, close on the cut | Shows the mistake being fixed |
| “The first frame decides everything” | A phone screen lighting up in a dark room | Turns an abstract claim into an image |
| “Caption the pause” | A waveform with a caption appearing at the gap | Makes the instruction visible |
Seedance 2 Fast is a sensible B-roll model: it renders quickly, supports the common aspect ratios and includes native audio if you want ambience. Generate drafts at 480p and keep the prompt to one action and one camera move. If a shot needs a specific look, use an image as the first frame and describe the motion, rather than describing the whole scene from scratch.
The Faceless Channel Maker is the shortcut when you do not want to write a shot list at all. Give it a topic and it writes an AI voice-over script plus cinematic B-roll, which is the same workflow with the planning step done for you. It is the closest thing to turning a post into a video in one pass.
Voiceover and captions
Generate the voice on the text to speech tab. ElevenLabs Multilingual V2 and Turbo 2.5, Google Gemini Flash TTS with 30 voices across 70+ languages, and xAI TTS are all available there, and you can download an MP3 on paid plans. Pick a voice that matches the post's tone: a practical guide reads better in a calm, clear voice than in a dramatic one.
Then caption it. Most feed viewers start muted, so the captions are not an accessibility extra; they are the primary text for a large share of the audience. Burn them in, keep them to one or two lines, and place them clear of the platform interface. If you are captioning an existing talking clip rather than generated B-roll, the AI Captions tool transcribes up to three minutes with word timing and lights each word as it is said.
Balance the levels. The voice should sit clearly above the music, and the music should drop under any dense sentence. If you cannot hear every word on a phone speaker, the mix is wrong. Our text to speech guide covers voice selection and pacing in more detail.
Aspect ratios for each platform
Decide the destination before you generate, because the frame changes what the shots can show. A 16:9 landscape has room for a wide scene; a 9:16 vertical rewards a single subject and a close camera.
| Destination | Ratio | What changes in the edit |
|---|---|---|
| Shorts, Reels, TikTok | 9:16 | Bigger captions, one subject, hook in the first second |
| Feed post | 1:1 or 4:5 | Product or face centred, text inside the safe area |
| YouTube, site embed | 16:9 | Wider shots, longer captions, room for a lower third |
If you need more than one, build the vertical version first and reframe the landscape from it, or the other way round. Rebuilding from the script twice is more work than resizing one master. The wider rules are in our aspect ratio guide.
Embed and repurpose
Put the vertical cut where short video lives, and embed the landscape cut in the blog post it came from. The embed does two things: it gives readers a second way to consume the same idea, and it gives the page a reason to stay open longer. Keep the video near the section it summarizes rather than at the very top, so it supports the text instead of replacing it.
Then repurpose rather than rebuild. The same 60-second script can become a captioned post, a carousel of stills pulled from the frames, and a short text post that links to the full article. Changing the wrapper is cheap; changing the idea is not. Our faceless YouTube channel guide covers the ongoing version of this workflow, where the video is the main product and the blog is the supporting text.
Frequently asked questions
How long should a video made from a blog post be?
About 60 seconds is a good default. It is long enough for one clear idea and short enough to finish before attention runs out. Longer posts can become a series of short videos rather than one long one.
Do I need to appear on camera?
No. You can use generated B-roll with a voiceover, or a faceless format. If you want a presenter, the avatar tools can put a photo to work instead.
Can I use the blog post text as the script?
Not word for word. Rewrite it for the ear with shorter sentences and one idea per line. The meaning can stay; the punctuation usually cannot.
What should I use for the voiceover?
Generate one on the text to speech tab with ElevenLabs, Gemini or xAI voices, or record your own. Pick a voice that matches the tone of the post.
Should the video go in the blog post or on social?
Both, in different cuts. Embed the landscape version in the post and publish the vertical version on short-video platforms.
Open the Faceless Channel Maker to turn a topic into a scripted voiceover and B-roll, or build the same video shot by shot from the text to video tab. There is no subscription needed, credits never expire, and new accounts get 10 free credits with no card, enough for a first 60-second test.
