A person, an action, a line
Create a 5–15 second character scene with generated sound. Image, video and audio references can guide the person, action and spoken moment.
Keep in mind
Audio is generated with the clip. 4K describes output size, not a guarantee of better motion.
Room for a longer scene
Build a scene up to 30 seconds, starting with text, an image or a mix of visual and audio references.
Keep in mind
Output goes up to 1080p. References guide the result; they do not guarantee an identical face or object.
Bring sound into the scene
Create from text, an image or references with audio generated alongside the video, up to 1080p.
Keep in mind
Generated audio still needs listening checks. For dialogue, review the exact words and mouth timing.
Start from a single image
Animate an opening image with generated audio, or explore a scene from text. Both routes offer output up to 1080p.
Keep in mind
The separate reference-to-video mode is limited to 720p. Check the mode, not just the model name.
Picture, sound and final frames
Explore text, image and reference workflows, including first-and-last-frame control and 4K output options.
Keep in mind
Duration and resolution choices depend on the mode. Check the exact combination before quoting a scene.
How we choose
H3 moves first for short character scenes with generated sound and mixed references. Seedance 2.5 gives a longer scene room to breathe. HappyHorse 1.1, Grok 1.5 and Veo 3.1 are alternatives to test with the same spoken line and framing.
This is an editorial order for starting your tests, not a measured quality ranking. We consider the available inputs, duration, audio and output options for this task. The clips use different prompts and settings; a single result cannot establish which model is best. Check the full model details before you create.
