Vidu Q4 预览版支持 4K：产品短片先验证镜头再升规格
Vidu Q4 Preview 公布 4K 输出和多参考素材能力。产品广告团队可先验证角色、产品与镜头衔接，再评估高规格交付和实际迭代费用。
10 月 7 日发布，当前仍以预览版介绍
生数科技在 10 月 7 日发布的新闻稿中介绍 Vidu Q4 Preview，列出多图、多段音频参考以及 2K、4K 输出能力。10 月 10 日的中文报道不是首次发布日期，本文按厂商新闻稿日期归档。
这些属于厂商能力说明，不能仅凭输出规格判断每个生成镜头都能满足商业交付要求。
产品短片先解决内容与衔接
广告团队可先确认产品在镜头中出现的时机、关键细节是否清楚，再评估角色表演和运镜。多张参考图能够提供更多制作依据，但仍需检查包装、服饰及道具在前后画面是否一致。
同一创意制作多个版本时，应保持核心产品资料和卖点不变，只调整开场或节奏。这样更容易比较哪种表达有效，避免把内容和画质同时改变后无法判断原因。
元链科技的观察：把迭代费用算完整
可以先用较低规格验证关键镜头，再测试最终输出。记录生成次数、可用片段比例与后期修正时间，按可交付成片计算成本。高分辨率无法自动修复错误的产品细节或不连贯的动作。我们尚未实测该版本。
预览与正式能力分别确认
厂商明确此次为完整 Q4 模型之前的预览发布。实际账号、地区、套餐、输出选择及素材商业使用条件应以入口规则为准，不能把首发宣传价格当作任何规格都适用的固定费用。
Announced October 7 as a preview
ShengShu Technology’s October 7 release introduces Vidu Q4 Preview with multiple image and audio references and 2K/4K output. The October 10 Chinese report is later coverage. This article uses the company release date.
These are vendor descriptions. Output resolution alone does not establish commercial suitability.
Validate the product message and transitions
First check when the product appears and whether important details are readable. More references can guide production, but packaging, clothing and props still need continuity review.
When comparing variations, keep core product facts and selling points unchanged while varying an opening or pacing. Changing everything at once makes results difficult to interpret.
Yuanlian’s perspective: count iteration costs
Test key shots at a lower specification before evaluating final output. Record attempts, usable footage and correction time, then calculate cost per deliverable film. Higher resolution cannot fix inaccurate details or broken actions. We have not tested this version.
Check preview conditions
The company describes this as a preview preceding the full Q4 model. Account, region, plan, output choices and commercial rights need confirmation. Launch pricing should not be assumed to cover every specification.
