什么是升频?

含义解析

在电子游戏中,升频是指将低分辨率的源素材渲染以适应更高分辨率显示器的数字过程。这是一种软件或硬件功能,而不是游戏卡带或光盘的物理属性。主流的等同概念是图像增强。对于收藏家来说,相关性在于性能:一个原生运行在 1080p 或 4K 的游戏,其体验优于从 480p 源素材进行升频的同一款游戏。这决定了在现代显示器上游玩时的视觉保真度。它属于*播放*的特性,而不是*产品*本身的特性。

对价格的影响

升频本身不会直接影响实体拷贝(卡带或光盘)的基础价格。然而,硬件的*能力*决定了其受欢迎程度。一个以出色的原生输出而闻名的主机或游戏(例如,一个支持真正 1080p 的系统),其价格会略高于一个以大量、易产生伪影的升频而闻名的产品。假设所有其他因素(状况、稀有度)相同,一个以原生方式运行的视觉要求高的 CIB(Complete In Box,完整盒装)版本,其售价可能比一个功能上相同但严重升频的版本高出 1.2 倍到 1.8 倍。例如,一款备受追捧的发布首发游戏,如果支持原生高清,其售价可能比严重依赖插值(interpolation)的同款游戏高出 20 美元。

如何识别

升频在实体物品上是看不见的。它是一个性能指标。要评估升频的潜力,请研究硬件的技术规格(例如,“这款主机输出 720p 还是 1080p?”)。卖家应该提供展示输出分辨率的游戏录像,而不仅仅是静态截图。与升频相关的版本标记是不存在的。一个常见的错误是卖家将游戏列为“HD Enhanced”(高清增强),而实际上只是被电视进行了升频,这是具有误导性的。务必要求提供在现代显示器上运行游戏的视频片段。

明智购买

仅基于游戏“可能”具有良好升频能力而支付溢价是存在风险的,除非该游戏已知具有强大的原生缩放能力。当游戏具有标志性的视觉效果,并且硬件被证明能很好地处理源素材时,支付溢价是值得的(例如,一个以干净缩放著称的系统)。一个公平的交易是标价反映了基础价值,如果确认硬件支持高保真输出,则增加一个可量化的少量溢价(低于 20%)。如果差异很大,那么这个溢价很可能是基于炒作,而非技术现实。

明智出售

在列出具有卓越原生输出能力的游戏时,值得在描述中提及这一点。不要使用“看起来很棒”之类的模糊术语。相反,陈述技术事实:“支持原生 1080p 输出。”这种精确的措辞会吸引那些愿意支付小额溢价的专业买家。“原生 (Native)”这个词是获得溢价的关键。明确说明游戏以最高支持分辨率原生运行的列表,将比通用列表表现更好,因为它能吸引视觉爱好者群体,通常比同类列表高出 10-15%。
