即便是 Google 剛推出的 Omni 模型,生成出來的效果也大輸 Seedance 2.0,很多人一定都想玩玩看 Seedance 2.0。只不過價格真的不便宜,一般來說也沒有免費的管道,但如果你是拿 iPhone 的話,有一個好消息,不知道是不是官方忘記關掉,還是其他原因,Krea AI 的 iOS 版目前影片生成功能中,有很多模型都能免費用,其中就包括 Seedance 2.0。更重要的是,還沒有任何限制,連 15 秒影片也能免費用。
這邊也先提醒一下,這看起來是 Krea AI 官方失誤不小心放出來,因此隨時都可能改掉,如果你用的時候不是免費,那代表已經改了。
現在可以免費無限量生成 Seedance 2.0 影片的方法,隨時可能會改掉
先到 App Store 安裝 Krea AI App,並免費註冊帳號和登入,接著再按照以下步驟操作。
進到 Krea AI 主畫面後,按下方的 Create Video,然後點輸入框下方的 Veo 3.1,就會打開模型選單,往下滑即可找到 Seedance 2.0,下面就標示著 Free with Quota,不花任何額度:
影片比例有 16:9 和 9:16,按最右邊圖示可展開更多功能選項,包括影片時間,預設 5 秒,最長可以設定到 15 秒:
解析度有 480p 和 720p 兩種,輸入提示詞並送出後,就會開始生成影片,我測試時大約 5 分鐘左右就完成:
這是我測試的第一部影片,時間設定 5 秒:
可以上傳首幀圖片,因此第二次測試 15 秒影片,我就有補首幀圖片,使用一樣的提示詞。尾幀圖片不知為何,我點都無法上傳,會一直覆蓋首幀的圖。15 秒生成時間就比較長,但也大概 5~7 分鐘左右就完成:
第二部測試的影片,15 秒:
還有其他影片生成模型也免費用,有標示 Free with Quota 就是,趁官方還沒修復之前也能玩玩看。
生成時,網頁版登入同一個帳號,也會顯示正在生成影片:
也能看到生成結果:
以下是我使用的提示詞,機器狗大戰外星人:
A futuristic sci-fi city at night, rain falling onto metallic streets, neon lights flickering in the background. A high-tech robotic dog is fighting an alien humanoid warrior in an abandoned urban district. The robotic dog is built with black titanium armor and a glowing blue energy core. Its eyes shine with sharp blue light, and it moves at extreme speed, capable of teleporting instantly to attack from different directions.
The opening shot starts with a low-angle slow push-in. The robotic dog growls and extends its mechanical claws, while the alien warrior raises an energy blade and prepares to fight. In the next second, the robotic dog teleports behind the enemy and launches a surprise attack. The camera quickly switches to a handheld tracking shot with intense motion, creating a thrilling and urgent combat rhythm. The alien warrior turns around and blocks the attack, causing bright energy sparks to scatter through the rain.
Then the camera cuts to an overhead aerial view. The robotic dog teleports repeatedly, leaving multiple blue afterimages as it attacks from the left, right, and above. The alien warrior is forced to retreat while swinging the energy blade to counterattack. The camera then cuts back to an extreme close-up, capturing the moment when the robotic dog’s metal claws scrape against the energy shield, sending sparks and rain droplets flying through the air.
Finally, the robotic dog teleports into midair and dives toward the alien warrior. The camera uses slow motion to show the moment of impact, as the ground cracks and blue energy explodes outward. The scene feels fast, intense, cinematic, and full of pressure. High-quality sci-fi action movie style, dynamic camera cuts, strong lighting contrast, neon rainy night atmosphere, thrilling and explosive, but no graphic violence or gore.
