An AI video generator
you can argue with.
Most text-to-video tools give you a clip and a shrug. Blob gives you a first cut you can change, describe the video, watch it get made, then keep talking until it is right.
- 01
Describe the video
One or two sentences is enough. "A 30-second explainer about our pricing change, calm tone, ends on a signup card."
- 02
Blob builds a first cut
It plans the shots, generates the footage (or uses yours), writes and reads the voiceover, scores it, and captions it.
- 03
Change it by saying so
"Make the intro shorter." "Warmer music." "Cut the third shot." Each note produces a new version you can watch.
Generation is the first draft, not the deliverable
The hard part of AI video was never producing something. It is producing something you can then fix. A generator that hands back an MP4 and no way to adjust it has moved the problem rather than solved it: you either accept what you got, or you start over with a slightly different prompt and hope.
Blob treats generation as a first draft. The video that comes back is a real project (shots, audio, captions and music are separate, addressable things), so the second instruction can be "swap the opening shot" rather than "try again, but different." That is the difference between a slot machine and a tool.
This matters more as the work gets longer. A five-second clip is cheap to reroll. A ninety-second explainer with a script, a voiceover and six shots is not, and rerolling it loses the parts that were already right.
What you can ask for
The instruction can describe the outcome rather than the mechanism. You do not need to know what a keyframe is, or which model produced which shot.
- A whole video from an idea. "A 45-second product announcement for a note-taking app, upbeat, vertical for Reels."
- A specific shot. "Add a slow push-in on a coffee shop at sunrise before the second line."
- A script and read. "Write the voiceover, keep it under 80 words, read it calm and unhurried."
- Music that behaves. "Score it, and duck the music under the voice."
- A format change. "Give me a 9:16 version and a 16:9 version of this."
The full vocabulary is broader than this, and you do not have to learn it, plain descriptions work. If you want a sense of what phrasing gets good results, the prompt guide collects the patterns that hold up.
Generated and filmed footage in one project
Most real videos are a mix. You have a talking-head recording and you need three cutaways you never shot. You have a product demo and you need an opening title sequence. You have nothing at all and you need something by Thursday.
Blob does not care which parts are yours. Upload footage and generate the rest, or generate everything, or start generated and replace shots with real ones as you get them. The instruction is the same either way: describe what should be there.
That is a practical difference from tools that split into "generator" and "editor" products. When the two are separate, moving between them means exporting, re-importing, and losing everything the first tool knew about your project.
Where AI video actually is right now
It is worth being straight about the state of the field, because the marketing around it is loud.
Adoption is genuinely broad. Adobe's survey of more than 16,000 creators across eight countries found 86% actively use creative generative AI, and Wyzowl found 63% of video marketers have used AI tools to create or edit video, up from 51% the year before. This is no longer an experiment at the edges.
What has not arrived is one-shot perfection. Generated footage still needs direction: a bad take is a bad take whether a camera or a model produced it. The tools that work in practice are the ones that make the second, third and tenth pass cheap. That is the bet Blob makes: not that the first generation will be right, but that fixing it should cost you a sentence.
Questions
- Can I generate a video without uploading any footage?
- Yes. Describe what you want and Blob plans the shots, generates the footage, writes and reads a voiceover, adds music and captions it. You can then change any part of it by describing the change.
- Can I mix generated footage with my own?
- Yes, in the same project. Upload what you have and ask Blob to generate the rest: an opening title, a cutaway you never shot, a closing card. There is no separate import step.
- How long can a generated video be?
- Short-form work (social posts, ads, explainers, intros) is what it is built for. Longer pieces work best when you generate them in sections and stitch them, which you can do inside one project.
- What does generating a video cost?
- Blob is pay-as-you-go, billed in plain dollars. You add funds and spend only on the work you run, so a short clip costs a fraction of a longer piece rather than both consuming a fixed monthly quota.
- Is my footage used to train AI models?
- No. Your uploads and projects are never used to train models.
