Cheapest AI Movie Maker

Every subscription in this category sells a credit allowance, and the allowance is what you are actually buying. Two plans at the same price can differ five-fold in how much finished film they produce, because the per-second rate of the model you spend them on differs five-fold.

Runway publishes both halves of its equation, which makes it the cleanest worked example. Standard is $15 a month for 625 credits, and Gen-4.5 text-to-video bills 12 credits a second. That is 52 seconds of video a month — Runway says so on its own pricing page — which works out at about $1.44 for a five-second clip, and worse if you do not spend the whole allowance, because Standard and Pro credits reset within 24 hours of your billing date rather than rolling over.

LTX Studio at $15 looks like the same price and is not the same product at that tier: its own pricing page puts consistent Elements, AI storyboards and the commercial-use licence at Standard, $35 a month. So the entry price for the thing most people mean by "AI movie maker" — script in, consistent characters out, allowed to use the result at work — is $35 there, not $15.

Katalist starts at $19 a month for one custom character and 700 video credits, with a seven-day trial on every tier. Ten custom characters is the $39 plan.

Three of the ten published models take a starting frame and nothing else. Grok Imagine Video is the cheapest clip in the roster at $0.23 for five seconds, and if your film has one recurring character in it, that is a false economy: ask it for a second shot of the same person and you get a different person, so you re-roll, and each re-roll bills.

Worked through: a one-minute film is 1,080 credits ($2.70) on Grok Imagine Video if every shot lands first time, against 3,900 credits ($9.75) on PixVerse C1, which carries the cast. The gap is about three re-rolls. Nobody gets a multi-shot film in one pass.

Which is also why "no sign up" is worth thinking about for two seconds rather than filtering on it. A tool that lets you generate anonymously is a tool that cannot keep a character sheet for you between sessions, and character sheets are the mechanism that makes a film cheaper than the sum of its re-rolls.

A large share of what ranks for this phrase is a timeline editor with AI features attached — you are cutting footage you already have, and the AI does captions, background removal and stock search. If you have clips and want them assembled, that is the right product and this page is not about it.

A smaller share generates the footage. Within that, the split is between clip generators (one prompt, one clip, no memory) and pipelines (script, cast, shot list, render). Both are represented at every price point, and the price you should compare is per finished minute rather than per month.

A third group is film-from-photos: you supply the images and the tool animates and sequences them. Cheaper than generating from scratch, and reference-driven models here will take your photos too — that is the same mechanism, from the other end.

Signing up puts 100 credits in your account, once, with no card. For a typical short story that is enough to go from your idea to a storyboard — the story brief, the script, the cast images and the shot plan — or, if you would rather, about 16 images in the image studio. A longer script or a bigger cast can use it up first, and the video itself is bought with credits.
