No music, no voices.

Train through a platform

A locked wide shot of a fast passenger train rushing through an empty countryside station platform, motion blur on the carriages, overcast light. Widescreen 21:9.

Street busker, vertical

A relaxed handheld medium shot of a street busker playing an acoustic guitar on a sunny cobblestone square, passers-by walking behind. Warm afternoon light, 9:16 vertical.

Cocktail shaker, close

A shallow-focus close shot of a bartender shaking a cocktail shaker behind a dim bar, then a smooth pour over fresh ice, moody amber lighting. Vertical 9:16.

Breakfast on the stove

A static cinematic close shot of bacon and eggs frying in a cast-iron pan in a cozy sunlit kitchen, steam rising, a kettle on the stove behind. Warm morning light through a window, 16:9. Audio: loud sizzling in the pan, a kettle starting to whistle, a soft morning radio playing low. No voices.

Campfire at dusk

A slow static shot of a campfire at dusk in a quiet forest clearing, logs crackling and sparks drifting up, deep blue twilight, warm firelight on the ground. Widescreen 21:9. Audio: fire crackling and popping, crickets chirping around, a soft gentle acoustic hum in the distance. No voices.

FAQs

How do I use these HeyGen Video 1 prompts?

Copy a prompt, change the subject and setting to match your idea, and keep the sound line. HeyGen Video 1 writes the picture and the audio in one pass, so the sound cue is part of the prompt, not an afterthought. Keep any spoken line short enough to finish inside a 5 to 15 second clip.

Were these clips made with HeyGen Video 1?

No. HeyGen Video 1 is not on Morphic, so each clip was made on Morphic with other models: the ambience and effect clips with Morphic H3, which generates native audio with the video, and the spoken-line clips with Veo 3.1. They show the kind of prompt HeyGen Video 1 is built for.

Why does every prompt name the sound?

Because the audio is generated with the picture, a clip is only as good as the sound you ask for. Naming the dialogue, ambience and effects plainly is what lets the model land them on the action, instead of returning a near-silent clip.

Can I run these prompts on Morphic?

Yes. The prompts work with Morphic H3 for native audio and Veo 3.1 for spoken dialogue. Open Copilot, paste a prompt, pick the aspect and resolution, and generate. The structure is the same one HeyGen Video 1 uses.

Can I use the clips commercially?

The prompts describe original scenes with no real people, brands or logos, so what you make from them is yours to use. Avoid prompting in a real person's likeness, a trademark or a copyrighted character.
