There's now an affordable way to create AI-generated videos — subscribe to xAI SuperGrok, generate your clips, then combine them into a finished movie. SuperGrok paired with MovieMaker Grok is the recommended way to make AI videos today — the cheapest, fastest, and highest-quality path available. Get started in the two steps below.
Generate your clips with xAI SuperGrok, then bring them to Movie Maker Edit to combine them. SuperGrok is the cheapest, fastest, and highest-quality option — use it while it lasts, as providers change their terms without much warning.
xAI SuperGrok — Grok Imagine Recommended
Open xAI SuperGrok →Bring your clips to Movie Maker Edit — stitch them into one continuous video, add a soundtrack, and export a finished MP4. It is free, needs no account and no API key, and runs entirely in your browser.
Open Movie Maker Edit →Movie Maker Edit is free — no account, no API key. The clip generator above requires its own paid subscription.
The good news: if you run out of free quota with your SuperGrok subscription, you can keep working on your long video without any 5-hour quotas. A BYOK version of MovieMaker Grok is provided. Here is how it works: just open MovieMaker Grok, get an xAI key — instructions are provided in the app — and enter your API key. Then you can create as many watermark-free video clips as you want for $0.07 per second of xAI API tokens that you pay for yourself. You won't even need a SuperGrok subscription to do this. Combine all your clips in the free Movie Maker Edit when you are done.
The BYOK version of MovieMaker Grok is free to use with your own API key and gives you full control:
MovieMaker Grok does not require a paid subscription — you only need a funded xAI API key. Detailed setup instructions are in the app itself.
Footnote — Google Gemini option (not recommended)
Google Gemini Pro and MovieMaker Gemini still work, but are not recommended at this time. Gemini costs more than Grok and produces less accurate videos in lower quantities. It only, at best, provides an alternative — a more costly and difficult path. Use it only if Grok cannot deliver exactly what you need and Gemini can, though this is rare.
Google Gemini Pro App (Veo 3.1). Up to 4K, up to 10 seconds per clip, with audio. Requires a Google Gemini Pro (or higher) subscription, min $19.99/mo. In practice you will be lucky to get one usable clip per 5-hour window before the quota slams shut for another five hours. If you accumulate these free clips over several days, you can still combine them in Movie Maker Edit.
BYOK MovieMaker Gemini. Roughly $0.40 per second — about 5.7× the price of Grok. It also requires a Google Gemini Pro or higher subscription (min $19.99/mo) and a paid Tier 1 or higher Google Cloud API key.
