Best AI tools for generating video

An AI creative suite for generating and editing video and images from text/image prompts, with in-house models (Gen-4, Gen-4.5) plus tools like Aleph (video-to-video) and Act-Two (performance transfer).

Professional and prosumer filmmakers and agencies needing controllable, production-quality generation and editing rather than one-shot novelty clips.

Free and Standard tiers cap out below 4K. The 125 free credits are one-time and never refresh. Gen-4.5 burns credits fast — about 25/second.

$0 — 125 one-time credits, Gen-4 Turbo plus Gen-4 text-to-image, 3 editor projects, 5GB storage.

Trains on user content by default across Free/Standard/Pro/Max tiers with no self-serve opt-out — only Enterprise can negotiate exclusion.

Flow is Google's AI filmmaking studio built on the Veo model family — text/image-to-video, scene extension, camera control, and multi-shot composition. Veo is also accessible via the Gemini app, AI Studio, and Vertex AI.

Short-form narrative filmmaking and storyboarding for creators, plus programmatic generation for developers via Vertex AI.

Consumer clips are short per generation (stitched into sequences). 1080p/4K require paid tiers. Daily and monthly credits don't roll over. Every output carries a SynthID watermark.

100 signup credits plus 50 credits/day (non-rolling), covering Veo 3.1 Lite/Fast/Quality — no published cap on total daily videos beyond the credit math (roughly 2-5/day).

Per Gemini's Apps Privacy Hub, human reviewers may review a subset of content to improve models; data is disconnected from the account before review and retained up to 3 years. No full model-improvement opt-out exists for the free consumer tier.

A generative platform for text-to-video, image-to-video, and image generation with fine controls — camera movement, object insert/removal, lip-sync, and native audio.

Fast, iterative short-clip generation for social creators and marketers wanting cinematic motion and camera control.

Free videos are capped at 720p with a watermark. Daily credits expire in 24 hours. Audio generation costs roughly 5x more credits than silent clips.

66 credits/day (non-rolling), reportedly around 6 five-second videos/day — the exact video-count-per-day is a third-party approximation, not a figure Kling states verbatim.

Broad data collection may be combined with third-party data to "improve Services" under legitimate interest; free-tier content may appear in a public community feed. Data is stored in Singapore, with no blanket opt-out described for free users.

An AI avatar video platform generating talking-head videos via stock or custom "Digital Twin" avatars, with text-to-speech and video translation/dubbing across 175+ languages.

Marketers and creators needing fast, scalable avatar videos, content localization, or personalized sales outreach video.

Free tier is capped at 1-minute videos; only Enterprise removes duration caps entirely. Unused credits expire on cancellation.

$0, no card required — 3 videos/month, up to 1 minute each, 500+ stock avatars, 1 custom Digital Twin, 30+ languages, watermarked (removal is paid).

HeyGen's Privacy Policy states user input — video, image, voice, and face data — is used "to train and enhance" its models by default. Users can opt out by emailing privacy@heygen.com; there's no self-serve toggle.

An AI avatar video generator focused on corporate training and e-learning, converting scripts into presenter-led videos using stock or "Personal Avatar" digital twins.

Corporate L&D, compliance/onboarding training, and SOP/product videos at scale without filming.

Free ("Basic") tier has no downloads at all. A photorealistic custom avatar is a separate $1,000/year add-on, annual-only. Only Enterprise gets unlimited minutes and personal avatars.

$0 ("Basic"), no card required — 1,200 credits/month (roughly 10 minutes of video), 9 stock AI avatars, 1 editor seat, but no export or download.

SOC 2 Type II, ISO 42001, and GDPR-compliant per its trust center — but exact default-training/opt-out mechanics couldn't be independently confirmed; verify directly against Synthesia's Privacy Policy before relying on a specific claim.
