Capabilities

What you can build with HeyGen Video

HeyGen Video is a general-purpose AI video model for creators and teams who need scenes, not stock. Generate a shot from a prompt, an image or your own references, then build it into finished video without leaving HeyGen.

Scenes around your digital twin

Your Avatar V digital twin delivers the message in your own face and voice. HeyGen Video builds the world around it: the factory floor you mention, the product you launch, the city you open in. Both land in the same HeyGen workspace, so a talking-head update becomes a produced film without a shoot.

Text to video with sound

Write what happens and what it sounds like. HeyGen Video generates subject, setting, light and audio in one pass, so every 5 to 15 second clip arrives with its own dialogue, room tone and effects. There is no separate voiceover pass or lip-sync step to run.

Twelve styles, one model

Live-action cinema, plasticine stop-motion, cel anime, watercolor wash, mid-century screen print, impasto oil: HeyGen Video's launch films covered twelve styles from the same model. Name a real production process, restrict the palette, and rule out the smooth digital default. Chain image to video shots from each last frame to move one drawing across media.

Reference-led control

Upload up to 9 images, 3 videos and 3 audio clips, 12 in total, and address each one in your prompt as Picture 1 or Video 1. HeyGen Video keeps the color, form and markings of the product you supply. Set a seed and the same prompt returns the same clip, so you change one clause at a time.

Use cases

How creators and brands use HeyGen Video

From founder updates and product launches to training explainers and short-form social, HeyGen Video supplies the shots a script needs: the establishing scene, the product close-up, the cutaway with real sound. Generate them alongside your avatar videos, all in one workflow inside HeyGen.

Social-first creative clips

Generate 9:16 hooks and transitions for TikTok, Instagram Reels and YouTube Shorts, with sound already in the clip. Short, contained shots with one subject and a still camera are where HeyGen Video performs best, which suits the first three seconds of a feed.

Founder & brand videos

Deliver the message with your digital twin, then cut to HeyGen Video scenes that show the warehouse, the product line or the city you are expanding into. Brand films that look shot on set start from a named camera and lens in the prompt.

Educational & explainer videos

Show the concept instead of describing it. Plasticine stop-motion suits onboarding and explainers that should feel handmade, and pencil sketch works for early design reviews. Keep hands still and let narration carry the procedure, since close hand work is one of the model's weaker areas.

Product launch content

Upload a product photo in reference to video mode and place it in any scene you describe, with its color and markings intact. Short launch lettering renders inside the shot when you spell it exactly and name it as the only text in frame.

"The magic moment for me was when I realized I could write a script, send it off, and never have to be on camera again — and HeyGen would handle the rest."

    常見問題

    Everything you need to know about HeyGen Video.

    甚麼是 HeyGen Video?

    HeyGen Video 是 HeyGen 的通用 AI 影片模型,以 MiniMax H3 為基礎,並由 HeyGen 進行後期訓練。它可根據提示詞生成完整場景,包括主體、環境、燈光及聲音,製作成 5 至 15 秒的短片。模型支援三種模式:文字生成影片、圖片生成影片及參考素材生成影片。在 HeyGen,您可於同一工作流程中,將它與您的 AI 數碼分身及其他模型配合使用。

    我可以使用 HeyGen Video 製作甚麼?

    您可以製作品牌影片鏡頭、產品場景、B-roll 插入鏡頭、社交媒體吸睛開場及風格化解說影片,每段均配有相符音訊。HeyGen Video 能保持場景連貫:物件的大小和位置維持一致,並遵循物理定律。它會嚴格按照簡介製作,因此只有在您提出要求時才會加入對白。對於只有一個主體、一個地點和一個動作的簡短獨立鏡頭,效果最佳。

    How do I access HeyGen Video on HeyGen?

    HeyGen Video is available through the HeyGen API as the model heygen-video-1, on paid API keys. Create a key in your API settings, then send a prompt and a mode to the create endpoint. Finished clips appear in your workspace alongside your other HeyGen videos.

    如何在 HeyGen 上使用 HeyGen Video?

    選擇模式,撰寫詳細的提示詞並提交。您可以使用文字生成影片來建立新場景、使用圖片生成影片以您自己的首幀作為開場,或使用參考生成影片來保留您提供的產品、人物或地點。詳細列明攝影機、鏡頭和聲音的長提示詞,效果比短提示詞更佳。輪詢工作狀態或設定回呼,然後下載 MP4。

    HeyGen Video 支援哪些解像度、影片長度和長寬比?

    影片片段長度可由 5 至 15 秒,解像度支援 480p、768p、1080p 或 2K,並編碼為每秒 24 格、配備立體聲音訊的 MP4。畫面比例包括 21:9、16:9、4:3、1:1、3:4 及 9:16,讓您可直接為 YouTube、TikTok、Reels 或 Shorts 生成影片,毋須重新裁剪。1080p 及 2K 僅支援以 16:9 或 9:16 輸出,費用為 768p 收費的 3 倍。

    輸出內容可安全用於商業用途嗎?

    可以。根據您的 HeyGen 商業授權,使用 HeyGen Video 生成的影片可用於商業用途,包括廣告、社交媒體帖文、產品發佈及客戶交付成果。為避免畫面中出現虛構品牌元素,請在提示詞中加入「不要出現標誌、品牌名稱、印刷文字或徽章」,否則即使是素色衣物和設備,也可能會出現虛構標記。

    Does HeyGen Video generate sound and dialogue?

    可以。環境底噪、音效和語音會根據同一提示詞與畫面一併生成,因此音訊會配合您所描述的場景。書面對白以每秒約 2.5 個英文單字為宜,即 15 秒片段約 37 個英文單字。如不需要背景音樂,請註明「不要音樂」。如需較長的腳本演繹,您的數碼分身可以用您的聲音說話。

    How does HeyGen Video compare to Seedance 2.0, Veo 3.1 and Sora 2?

    Seedance 2.0, and Veo 3.1 are known for complex, multi-shot cinematic motion. HeyGen Video competes on control: literal prompt following, sound from the same prompt, up to 12 references and repeatable seeds. The bigger advantage on HeyGen is workflow. You pick the right model for each shot, then add avatars, voice and captions in one place.

    我可以使用 HeyGen Video 兩次生成相同的影片片段嗎?

    Yes. Set the seed yourself and the same prompt with the same seed, submitted in succession, returns an identical file. Hold the seed and change one clause at a time to iterate. When the seed is omitted the server picks a random one, so two identical requests return different videos. The completed job reports the seed it used.

    HeyGen Video 會改寫我的提示詞嗎?

    只有在您允許的情況下才會如此。提示詞增強功能可以改寫提示詞的其餘部分,因此,如果您希望文字完全按原文保留,請停用此功能。您亦可以傳入一個回呼 URL,以便在工作完成時收到通知,毋須輪詢結果。

    無論您想製作甚麼,現在都能實現

    立即開始使用 HeyGen Video 及 HeyGen AI Studio 的其他功能。毋須拍攝,亦毋須製作團隊:建立 API 金鑰,幾分鐘內即可送出您的第一個提示詞。

    • 一次操作即可將提示詞轉換成短片
    • 每段影片均有聲音
    • 可透過種子值重複生成
