There is no single best AI video generator — the right one depends on what you ship. MakeThisVid is built for short-form ad and social clips: 6-second 720p or 8-second 1080p video with audio baked in, commercial use licensed on every plan, from $19.99/mo for 10 credits or a $2.99 one-time pack. For longer cinematic single shots, Runway. For narrative scenes, Sora. For talking-head avatars, Synthesia or HeyGen.

Best AI Video Generator: How to Pick One

By MakeThisVid Editorial Updated Methodology
Real output — prompt: "A futuristic city skyline at dusk, neon signs reflected in rain puddles, camera slowly tilting up, cinematic colour grade"

"Best AI video generator" is a question that breaks the moment you ask it seriously. Best for what? A six-second paid social ad, a one-minute explainer, a talking-head training module, and a cinematic short are four different jobs — and four different tools. This page maps the honest criteria, then names the tool that wins each lane. MakeThisVid wins one lane: short-form ad and social clips with audio.

How to Use MakeThisVid

From prompt to downloadable MP4, ready to deploy.

  1. Pick the lane before the tool

    Short ad clips, long explainers, avatar presenters, and cinematic shorts use different generators. Decide what you are actually shipping before reading any "top 10" list — the same list reads differently depending on the answer.

  2. Filter on commercial use and watermark

    If the output runs as a paid ad or ships to a client, both have to be unambiguous. MakeThisVid licenses commercial use on every plan and the $2.99 starter pack and never adds a watermark. Most no-cost tiers explicitly exclude commercial use — the clip looks fine but is not legally runnable.

  3. Look at cost per clip, not monthly fee

    A $10/mo plan with 5 credits costs more per clip than a $79.99/mo plan with 60. MakeThisVid Pro lands at ~$1.33 per 720p clip with audio — divide credits into monthly fee on any plan before signing up.

  4. Test with a single pack first

    On MakeThisVid the $2.99 Starter Pack ships one 720p clip; the $4.99 Starter HD Pack ships one 1080p clip with audio and commercial use rights — no subscription required. Run a real prompt through it, decide if the output fits your brand, then upgrade if it does.

  5. Generate, download, ship

    Prompt → 45-90 seconds → MP4 with audio baked in, no watermark, commercial use included. Drop straight into Meta Ads Manager, Google Ads, the post scheduler, or a client brief. If a render fails for any reason, the credit is refunded automatically.

Who Uses MakeThisVid for This

MakeThisVid — best for short-form ad and social clips

Purpose-built for 6-second 720p or 8-second 1080p video ads with audio. Lite $19.99/mo (10 credits), Standard $49.99/mo (30 credits), Pro $79.99/mo (60 credits). Or $2.99 one-time for a single clip. Commercial use included on every plan and pack.

Runway Gen-3 / Gen-4 — best for longer cinematic single shots

Strong for one cinematic clip up to 10 seconds with detailed motion control. Output is silent — bring your own audio. Subscription starts at ~$15/mo. Best when each frame matters more than throughput.

Sora (OpenAI) — best for narrative scene generation

Highest fidelity for story-driven prompts and longer scenes. Access via ChatGPT Pro ($200/mo). Best when a single scene needs to read as a narrative beat.

Synthesia / HeyGen — best for talking-head avatars

Avatar presenter video with multilingual voice for training, internal comms, or explainer modules. The wrong category if you need synthesized scenes; the right one if you need a presenter.

Pictory / InVideo / Fliki — best for repurposing-to-video

Stock-assembly tools that turn blog posts and scripts into longer-form videos with voice-over. Useful for content reformatting, not for original ad creative.

MakeThisVid. It generates 6-second 720p or 8-second 1080p video clips with audio and commercial use rights on every plan, from $19.99/mo for 10 credits or a $2.99 one-time pack. The format and licensing match how paid social ads ship.
MakeThisVid Pro lands at roughly $1.33 per 720p clip with audio (60 credits for $79.99/mo). The cheapest entry without a subscription is the $2.99 Starter Pack — a single 720p clip with commercial use rights. The cheapest 1080p entry is the $4.99 Starter HD Pack.
MakeThisVid bakes audio into every render — no separate step, no upgrade. Runway, Pika, Kling, and Luma output silent clips. Synthesia, HeyGen, and Fliki include voice but they are avatar or stock-assembly tools, not scene generators.
Most generators ship watermarks on no-cost tiers because rendering is GPU-expensive. MakeThisVid has no no-cost option — the lowest entry point is the $2.99 one-time pack, which produces one 720p clip with audio, no watermark, and commercial use rights. The cheapest 1080p entry is the $4.99 Starter HD Pack.
MakeThisVid renders 6-second 720p or 8-second 1080p clips per generation. For longer pieces, generate multiple clips and stitch them together — this is the standard workflow for ad sequences. Sora supports up to ~20 seconds in a single render; Runway Gen-3 supports up to 10.
