Premium beverage product film, one continuous five-second shot. A single tall clear glass filled with sparkling orange citrus drink and clear ice cubes stands on a pale gray stone pedestal, a small lemon wedge on the left and one green leaf on the right, clean muted turquoise studio background. Soft daylight from upper left glints through the glass. The camera makes a slow, subtle clockwise orbit while keeping the entire glass centered. Tiny bubbles rise naturally and condensation glistens. Preserve the glass shape and orange drink color throughout. No cuts, no hands, no text, no logos, no music, no speech. Silent video.

Create one continuous five-second product shot from the supplied first frame to the supplied last frame. Keep the camera locked, with exactly the same clear glass, ice cubes, stone pedestal, lemon wedge, green leaf, turquoise background and soft upper-left lighting. A thin stream of orange citrus drink pours naturally from above the top edge into the glass. The liquid level gradually rises from the first-frame level to the last-frame level; the ice floats upward slightly, bubbles and ripples behave naturally. The pouring stream stops before the end and the final image settles into the supplied last-frame composition. No cuts, no new objects, no hands, no text, no logos. Silent video, no music or speech.

Use the supplied reference image to preserve the exact clear highball glass, orange citrus drink, ice, stone pedestal, lemon wedge and green leaf. Use the reference video only for its slow clockwise camera orbit and soft lighting rhythm. Create a fresh five-second premium beverage product shot in the same muted turquoise studio setting. Begin with the whole glass centered, make a small smooth clockwise orbit and finish slightly closer while retaining the entire glass. Keep the liquid level and glass shape consistent with the image; tiny bubbles rise naturally. One continuous shot, no cuts, no added objects, no text, no logos. Silent video, no music or speech.

Seedance 2.0 图生视频

在 API Hop 使用 Seedance 2.0 图生视频 API,登录后上传一张图片,再用文字提示词描述主体与镜头运动。本模式仅使用一张首帧图片,不接收尾帧。

图生视频:输入与参数

选择主体清晰、构图适合目标片段的图片。登录后上传不超过 10 MiB 的 PNG、JPEG 或 WebP 图片;账号上传返回的素材 URL 会用于视频请求。

图片确定起始构图

上传的图片以 first_frame 角色提交,用于指导视频起点;这不代表成片每个像素或细节都会始终保持原样。

先完成上传,再提交生成

等待上传完成后再生成视频。本地路径、blob URL 和图片 data URI 不会直接作为生成素材提交。更换创意时可以替换或移除图片。

描述运动,而不是重新画出图片

写明主体动作、镜头路径和需要保留的特征。选择 4-15 秒固定整数时长、480p、720p、1080p 或 4k 分辨率,以及适合原图的输出比例。生成音频是独立的可选设置。

音视频联合生成与输出检查

Seedance 2.0 可生成与画面配合的声音,适合在短镜头中探索环境声、动作音效与对白。生成音频是独立输出设置;是否提供参考音频取决于输入模式,不能把模型支持多模态理解为每个页面都接受所有素材。

图生视频:检查生成结果

视频质量需要结合真实输入和目标用途检查。本节按可观察的成片标准评估,不把演示效果或单个样例当作画质、延迟或业务成功率承诺。

起始构图与主体身份

对照原图检查视频开头,再沿整个片段检查主体。留意轮廓、材质、重要细节和背景位置,不把输入图片视为还原度保证。

运动与镜头稳定性

检查运动是否来自预期的主体或镜头。连续观看整个片段,留意不必要的形变、重复细节和突然的透视变化。

检查开头与整个动态过程

沿整个片段检查起始构图、主体身份和运动。任务成功不代表图片已经在视觉上保持一致。

结尾需要特定图片时使用首尾帧;需要其他素材指导外观、运动或声音时使用多模态参考。

记录完整耗时、返工与实际费用

用同一组任务记录从提交到结果可用的时间、需要修改的次数和账户费用。区分队列等待、任务完成与人工验收;先找到可接受的质量和预算,再扩大生成数量,不根据一次等待推断稳定服务速度。

API 请求与任务跟踪

将当前模式的请求提交至 POST /v1/video/seedance,再用返回的任务 ID 查询 GET /v1/jobs/{jobId}。等待 COMPLETED 且含有输出后再使用结果;查询已有任务不需要重新提交生成。

Seedance 2.0 图生视频常见问题

可以上传哪些图片?

登录后可以上传一张不超过 10 MiB 的 PNG、JPEG 或 WebP 文件。鉴权上传会返回素材 URL;不要把本地文件路径或图片 data URI 直接放进视频生成请求。

图生视频可以添加第二张图片吗?

不可以。本模式只接受一张 first_frame 图片。需要可选结束画面时使用首尾帧,需要多份素材输入时使用多模态参考。

图生视频使用另一个 Seedance 2.0 模型吗?

不是。它仍使用 model: seedance-2.0,通过同一个异步视频 API 提交一张 first_frame 图片。独立模式将单图工作流与纯文字及多素材任务区分开。

输入图片会被精确复现吗?

不能假定逐像素保留。图片指导起始构图,提示词指导运动。接受结果前,请检查开头和后续画面。

Seedance 2.0 四个页面使用不同的 model 参数吗?

不是。四种输入模式均使用 model: seedance-2.0,通过 POST /v1/video/seedance 提交异步视频任务,再用 GET /v1/jobs/{jobId} 查询。不要把页面模式名、显示名称或其他模型 ID 当作接口中的 model。

Seedance 2.0 支持哪些时长与输出设置?

当前 API Hop 接口使用 4-15 秒整数时长,默认 5 秒,支持 480p、720p、1080p、4k,以及 16:9、9:16、1:1、4:3、3:4、21:9、adaptive 比例。生成音频单独设置;不使用 -1 自动时长,也不要自行添加 seed、negativePrompt 或其他未列出的参数。

遇到鉴权、余额或生成错误怎么办?

先核对 Bearer 鉴权、账户余额、seedance-2.0 模型权限和当前模式所需输入,再检查素材地址是否可访问。保留完整错误与任务 ID,并区分提交失败、等待中和任务失败;不要只看一个数字错误码就判断原因。

Seedance 2.0 生成费用如何确认?

先在本页价格区核对分辨率、时长与是否包含视频输入对应的价格,再结合账户记录确认实际费用。价格暂不可用不代表免费;不要把其他版本或文本模型的单价用于推算本次视频任务。
