Official details ↗Text to Video Tools
AI text-to-video tools turn written instructions into video, but they do not all produce the same kind of result. Some generate a scene from a visual prompt; others turn a script into a talking-presenter video. Browse the tools below, filter by catalogue pricing, and use the source-linked comparison to shortlist the workflow you need. Check the chosen model, export limits and revision costs before paying for a plan.
Pricing labels come from catalogue records and may change. A trial is not an ongoing free plan; check the provider before subscribing.

|---|---|---|---|
| Runway Gen-4.5Official source ↗ | Text-to-video and image-to-video scene generation. | 2–10-second clips; 720p output; 24 or 25 fps. | Standard plan or higher; documented cost is 12 credits per second. Check the aspect ratios available for the selected input mode. |
| Adobe Firefly video generatorOfficial source ↗ | Generate video from a text prompt or an image. | Workspace offers Adobe’s Firefly Video Model and partner video models. | Compare the selected model rather than treating every Firefly model as identical. Confirm its current credit cost, export options and plan access. |

Evaluate pronunciation and delivery separately from cinematic scene generation; check current plan limits. |
What is text-to-video AI?
Text-to-video describes workflows that start with written input. In scene generation, the prompt describes a subject, setting, action and camera movement. In a presenter workflow, a script supplies the words an avatar will speak. These outputs serve different purposes: a generated establishing shot cannot replace a narrated explanation, and an avatar reading a script is not a test of a model’s ability to generate a complex scene.
Text-to-video vs. image-to-video
Start with text when you want to explore a scene without supplying its first frame. Start with an image when the composition or appearance of a supplied subject matters. Image input can constrain the starting point, but you still need to inspect motion and consistency throughout the clip. If you already have a product photograph, compare reference-based tools in the image-to-video collection before regenerating the product from words.
How to turn a text prompt into a useful video
Use a small, repeatable brief before attempting a complete production. This is a suggested workflow, not a published Artificin benchmark.
- Choose a deliverable: a generated scene or a scripted presenter. Set the required orientation and clip length.
- Write one clear shot: “A ceramic mug on a wooden desk. The camera slowly moves left while the mug stays still. Soft window light.”
- Select the model and inspect its generation cost before submitting. For a presenter, supply the spoken script instead of a camera prompt.
- Watch the entire result. Check object shape, unwanted movement, timing and any audio you requested.
- Change one instruction at a time. Keep track of attempts and export the accepted clip at the required dimensions.
How to choose an AI text-to-video generator
- Follow the scene description: Specify the subject, setting and one action. Check omissions, extra objects and changes to the action before evaluating visual polish.
- Maintain continuity: Watch objects entering and leaving the frame, changes of direction and the end of the shot. Record inconsistencies that would prevent using the clip.
- Revise predictably: Change one instruction at a time. Compare whether revisions improve the requested detail without breaking the rest, including the final delivery format.
Free plans, credits and the cost of a finished clip
A free account, a short trial and an ongoing free video allowance are different offers. Check whether the exact video model is included, whether exports carry a watermark, and whether failed attempts consume credits. Compare cost per accepted clip rather than advertised subscription price alone. A plan that produces more attempts is not necessarily cheaper if most results need replacing.
A useful test before you subscribe
Write a brief for one short, continuous shot with no cuts and three observable requirements. Keep the brief and attempt budget consistent across tools. Count accepted seconds after reviewing the whole clip and include rejected attempts in the cost.
Text to Video FAQ
What is the best AI text-to-video generator?
The right choice depends on the output. Compare scene generators for visual prompts and avatar tools for scripted explanations. Use the same brief and attempt budget, then assess continuity, editability, export requirements and total cost. This page compares documented capabilities and does not publish a hands-on winner.
Can I generate AI videos from text for free?
Some providers offer trials or limited free access, but that does not mean every model or export is included. Check the specific model, credit allowance, watermark rules and download limits. The directory’s Free and Freemium labels are starting points, not guarantees of unlimited video generation.
Do text-to-video generators also support images?
Some do. Runway documents both text-to-video and image-to-video for Gen-4.5, and Adobe describes both inputs for its video generator. Input controls and available settings can differ by model. Use the linked provider documentation to check the workflow you plan to use.
Does text-to-video include speech or sound?
Do not assume that a generated clip includes audio. Check the exact model and workflow. HeyGen’s avatar workflow is designed around a spoken script; scene generation, voiceover and sound effects may be separate operations in other tools.
How do I make longer videos from short generated clips?
Plan a sequence of shots, generate them separately, and assemble accepted clips in a video editor. Check transitions, colour, subject consistency and audio across cuts. A longer final edit is different from a model generating one uninterrupted long shot.
