The verdict
Which one should you pick?
Hedra
Pick it for
- Talking-character explainers and spokesperson videos from a single portrait
- UGC-style ads and product walkthroughs with an illustrated or AI-generated presenter
- Music videos and animated shorts where a character must sing or talk on camera
Stands out
- Built for character performance first: one portrait plus audio gives lip-sync, expression and gesture, and it works on illustrated characters as well as photos.
- Character-3 clips run up to 10 minutes per generation, far longer than most single-shot video models, and are priced per second at 2.5c (540p), 5c (720p) or 6.25c (1080p).
Watch out
- Output tops out at 1080p on Character-3 and Omnia, below 4K-capable rivals
- Credits expire monthly and do not roll over, according to third-party reviews
Kling AI
Pick it for
- Character-driven short films that need the same actor across many shots
- Previs and storyboard visualisation from shot-by-shot prompts
- Multi-language talking-head and dubbed social content
Stands out
- Video 3.0 Omni reference system: carries a character's look, expressions and voice traits from reference clips into new shots
- Storyboarding sets duration, shot size, perspective and camera movement per shot, which few generators expose this directly
Watch out
- Free output is watermarked and not for commercial use
- Lip-sync and voice are less of a focus than dedicated voice tools (ElevenLabs, HeyGen)
Krea
Pick it for
- Pre-visualization: moodboards, look development and concept stills for a shoot
- Producers who want Seedance, Nano Banana and ChatGPT Image in one account instead of three subscriptions
- Motion designers generating short hero clips with a reference image and a generated soundtrack
Stands out
- One compute balance covers Krea's own models plus third-party image and video models (Seedance 2.5, Nano Banana Pro, ChatGPT Image 2, Kling, Topaz), so you do not need a separate subscription per model.
- Canvas, node workflows and the Krea Agent sit in the same product, so a brief can be run as a chat or built as a visual graph.
Watch out
- Compute units are opaque: per-model costs are not published, so budgeting video is guesswork
- Native video is capped at 720p for Seedance 2.5; 1080p and 4K need Seedance 2.0
Runway
Pick it for
- Previs and shot tests with Gen-4.5 before committing to a shoot
- Fixing finished footage with Aleph 2.0, such as swapping backgrounds or wardrobe across a clip
- Agency ad and campaign work using Agent, Brand Kits and Projects
Stands out
- Gen-4.5 and Aleph 2.0 sit in one credit pool with third-party models such as Kling 3.0, Seedance 2.5, Wan 3.0 and Nano Banana Pro, so you can compare models without separate subscriptions.
- Aleph 2.0 edits existing footage rather than generating new clips, which keeps the rest of a shot stable.
Watch out
- Credits burn fast: about 12 credits per second for Gen-4.5 and about 28 for Aleph 2.0
- Single generations run about 10 seconds, so longer scenes need stitching
