Price at the same settings
What to compare visually
For a fair A/B test, use the same scene and, where both modes allow it, the same first frame. Inspect motion continuity, character and object consistency, physics and contacts, camera behavior, temporal deformation, in-clip cuts and audio synchronization.
What to inspect with HappyHorse 1.1
A short scene with sound, from text, a starting image or a set of photos.
- Text, one image or references with up to 9 photos.
- 3–15 seconds at 720p or 1080p, with a choice of aspect ratios.
- More photos do not guarantee preservation of every small detail.
- Inspect hand-object contact and speech synchronization separately.
What to inspect with HeyGen Video
Creates videos with sound from a text prompt or a single source image.
- Text: the result is created from a written description.
- Every available setting is shown in the Studio form before launch, and the price follows them.
- The result length is 5 to 15 seconds.
- At most 1 photo as input.
How to run a fair comparison
- Fix the scene, the first frame (if both models accept one), the duration and the resolution.
- Judge motion, not stills: faces, hands and objects should hold across the whole clip and at cuts.
- If sound matters, listen to it separately: dialogue, effects and lip sync differ between models.
- Price a finished clip, not a second: the per-second rate times your real duration, rounded up once.
