AI Video Generator: Turn Scripts Into Vertical Social Videos

Short-form video is easier to plan when the message starts with a clear script. The MXPROCESS AI Video Generator helps creators, agencies and marketing teams turn written ideas into vertical social videos with narration, captions and scene visuals. It is useful when you need a repeatable way to turn approved copy into assets for a campaign, product update, educational post or social series.

Create a vertical video from a script you control

Use the interface to paste a script, upload a TXT or JSON file, or provide an HTTPS URL to an approved source. A simple text script can become one video. For a more structured workflow, provide up to four scripts in JSON and prepare several related videos in one request. This is practical for a week of social posts, a multi-part explanation or alternative messages for different audiences.

The structured format supports a hook, introduction, body, conclusion and call to action. These sections help keep the narrative focused: start with the idea that earns attention, explain the value, then end with a clear next step. Always review facts, claims, names and brand language in the source before submitting it.

Choose the language, pacing and audio presentation

Set the language used for your content, choose a voice and adjust its speed between 0.85 and 1.25. You can set a maximum duration from 15 to 90 seconds; 60 seconds is the default. The limit gives your team a clear editorial constraint for short-form channels and helps you keep each message concise.

You can also choose whether to add ambient background music. The resulting video keeps the selected narration and includes captions so viewers can follow the message in sound-on and sound-off contexts. These choices make the interface suitable for teams that want consistent creative parameters without recreating the same setup for every script.

Receive review-ready files for your publishing workflow

For every accepted script, the service provides a vertical MP4 video and a JSON manifest. The manifest records the title, duration and content structure used for that video, which can help your team organize approvals and keep project records. A request can produce up to four videos, provided that each script fits the chosen duration.

The service does not publish videos automatically. Your editor or social media manager can review the rendered asset, confirm that it matches the approved copy and visual standards, then publish it through the channels and schedule your organization chooses.

Use the API for repeatable content operations

The authenticated MXPROCESS API accepts the same source choices and options as the interface: script text or JSON, an uploaded TXT/JSON file or HTTPS URL, language, maximum duration, voice, voice speed and background music. Submit the request to the existing asynchronous endpoint, keep the returned tracking information, and collect the MP4 and JSON results when processing is complete.

This handoff suits content platforms, agencies and internal marketing operations that already manage scripts in a CMS, approval tool or campaign calendar. Your application can submit approved copy, track the request, store the resulting files with the campaign and leave the final publishing decision with a human reviewer.

Start with an approved message

Choose a concise script, set the audience language and desired duration, and keep the call to action aligned with your campaign. Visit the AI Video Generator to prepare vertical video assets from the content your team has approved.
