2026 年 10 月 11 日晚 19:30，《2026 美好奇妙夜》如约登场。
异形主屏融入 "时光之眼" 概念，超 3000 盏数控灯与全场数控荧光棒交相辉映，AIGC 实时渲染将虚拟与现实叠合于同一帧画面 —— 这场被外界称为 "中国室内直播晚会视觉技术新纪录" 的科技盛宴，在国家速滑馆 "冰丝带"拉开了帷幕。
不过，当观众惊叹于舞台巨幕上清晰细腻的视觉呈现时，可能很难想到，这些出现在 20 米巨幕上的画面，原始素材分辨率其实只有 720P 或 1080P。
将 720P/1080P 的视频素材撑上 20 米舞台巨幕，放大到 8K 分辨率播放而不露任何瑕疵—— 这背后，是火山引擎 AI MediaKit 针对巨幕场景推出的超分方案。
一场远超常规的分辨率跨越
超分辨率在视频技术领域并非新概念，但面向巨幕场景的超分，面临的是一道远超常规的超分难题。
常规的超分场景，是将低分辨率视频提升 2 倍或 4 倍，在手机或电脑屏幕上观看。而美好奇妙夜的舞台巨幕宽达 20 米，实际播放分辨率要求达到 8K。这意味着，原始 720P 素材需要被放大数十倍—— 每一个原始像素，都要被 "脑补" 出上百个新像素来填补。手机屏幕小，同样的画质瑕疵不容易被发现；但舞台巨幕上，任何一处纹理模糊、边缘锯齿、色彩断层，都会被放大到肉眼可见。
算法要为每一帧画面“生成”出大量像素 —— 皮肤上的毛孔、丝绸上的经纬纹路、羽毛的纤细分叉，这些在原始素材里不存在的细节，都需要模型根据画面语义 "生成" 出来，还得生成得准、生成得稳。
逐帧估算：为每一帧画面 "补全" 细腻纹理
火山引擎 AI MediaKit 巨幕超分方案的核心，是通过算法逐帧估算，补全画面的细腻纹理与边缘细节。与传统视频超分方案不同，这套方案的本质是生成式补全—— 模型理解画面内容后，生成原始素材中没有的纹理细节。
第一，逐帧纹理生成。 模型对每一帧画面进行语义级理解，识别出皮肤、织物、羽毛、金属、水波等不同材质区域，针对不同纹理特征采用差异化的生成策略。羽毛的纤细分叉、光泽渐变、层次叠压，在 720P 原始素材中，往往只能保留有限的信息，经过模型逐帧补全后，在 8K 巨幕上则能够呈现出肉眼可辨的细腻纹理。
第二，边缘细节重建。 在巨幕播放场景下，画面放大后容易暴露边缘接缝、轮廓发虚和纹理断裂等问题。针对这些情况， AI MediaKit 巨幕超分方案进一步优化了关键区域的细节表现，让画面在大屏观看时保持更自然、稳定的清晰度。
第三，时序一致性保障。 视频不是静态图片，连续帧之间的 "跳变" 是超分技术的隐形杀手。如果每一帧独立处理，画面可能出现帧间闪烁、纹理漂移。巨幕超分方案引入时序约束机制，确保补全的纹理在前后帧之间保持连贯，让巨幕上的画面如丝般顺滑。
二十米级大屏需要真实像素密度支撑，远看有气势，近看有细节。
舞台光照、运动画面和大面积屏幕同时存在，对稳定性要求更高。
面向传播与现场观看，画面不能只锐化，还要自然、干净、连续。
高分辨率母版让巨幕画面保留层次，不因尺寸放大而显得松散。
复杂光影和快速运动中，清晰度、稳定性和自然感需要同时成立。
AI MediaKit 面向巨幕场景的工程化落地
在 2026 抖音美好奇妙夜，火山引擎 AI MediaKit 巨幕超分方案主要用于播放素材的画质增强，让 720P/1080P 可以通过超分达到适配巨幕大屏的超高分辨率的播放需求。同时，配套的色彩与明暗细节增强能力也有助于进一步提升画面在巨幕场景下的整体观感。目前火山引擎已支持最高 16 bit 全范围色深输出，能够大幅改善大屏画面的色彩过渡和细节表现。最终让经过增强处理的素材在舞台巨幕上呈现出更清晰、更稳定、更完整的视觉效果。
对于这类项目而言，难点不仅在于画质增强本身，还在于能否在有限的制作周期内实现稳定交付。火山引擎凭借在长短视频业务中积累的超大规模视频处理能力，将这条从低分辨率超分至 8K 的画质增强链路打磨至工程级可靠，确保每一个节目在登上巨幕时，都呈现出最佳状态。而且这套方案的技术上限远不止于此，最高可支持将画面增强至 16K/32K 分辨率，为未来更大尺寸、更高规格的巨幕场景预留了充足的技术余量。
随着 AIGC 内容、AI 生成视频在晚会和大型活动中的应用越来越普遍，原始素材分辨率与终端播放规格之间的差距只会越来越大。火山引擎 AI MediaKit 巨幕超分要解决的，正是这一类实际制作问题：在控制制作成本的同时，帮助更多素材适配大屏和巨幕场景，提升最终呈现的清晰度、稳定性与观感质量。
这项能力的意义也不止于一次舞台应用。早在 2026 年春晚中，火山引擎就曾依托同款超分能力，将 Seedance 2.0 生成的 720P 视频增强至 8K，成功登上央视春晚大屏。无论是舞台演出、品牌发布，还是文旅展陈，历史素材、普通高清素材和 AIGC 素材都可以通过增强处理，更好满足超大屏播放需求。随着显示规格不断提升，巨幕超分也有望进一步拓展到沉浸式空间、数字艺术展示、商业大屏、城市公共显示以及大型赛事和活动现场等更多场景。未来，火山引擎智能视频云将继续用过硬的技术能力，为更多行业客户提供可靠且稳定的 AI MediaKit 巨幕超分解决方案。

On the evening of October 11th, 2026, 19:30, The Great Night 2026 came out as promised.
The Alien main screen incorporates the concept of "The Eye of Time", with over 3000 digital lamps conjoining with the full range of digital fluorescent rods, and AIGC in real time replays virtuality and reality in the same frame -- a technological event called "New Record of Visualization at China's Indoor Live Nights" that opened a screen in the National Skide.
However, it may be difficult to imagine when the audience is amazed by the clarity and detail of the visual appearance on the scene, that these images appear on the 20-metre screen, the original assetresolution is actually only 720 P or 1080 P.
The video asset of 720P/1080P has been extended to a 20-metre stage screen, zooming in to 8K resolution without any defects -- behind this is Volcengine AI MediaKit's hyperscore program for the scene.
A far more conventional resolution cross. Viet.
SuperZ resolution is not a new concept in the area of video technology, but it is a far more conventional hyper-spectrum problem for the super-spectrum view.
The normal hyperspection is two or four times higher than the low resolution video, which is viewed on a mobile phone or computer screen. And the scene of the wonderful night is 20 meters wide, actually playing resolution for 8K. This means that the original 720P asset needs to be magnified dozens of times -- every original pixel, filled with hundreds of new pixels from the brain. Cell phone screens are small, and the same painting defects are not easily detected; however, any texture, edge sawn, colour faults on the stage screen are magnified to the eye.
Algorithms to "generate" large amounts of pixels for each frame -- fur holes on the skin, parallel paths on silk, fiber-division forks on feathers that do not exist in the original asset, require models to be "generated" in the sense of the image, and they have to be generated correctly and steadily.
Frame-by-frame estimation: "Purpose" for each frame
At the heart of the Volcengine AI MediaKit superspect scheme is a frame-by-frame estimation to complete the fine texture and edge details of the picture. Unlike the traditional video hyperscore, the essence of the package is to generate a complete -- a model that understands the content of the image and generates texture details that are not found in the original asset.
First, frame-by-frame texture generation. The model provides a symmetrical understanding of each frame, identifies different material areas such as skin, fabric, feathers, metals, water waves, and uses differentiated production strategies for different texture characteristics. In the original asset of 720 P feathers, which are broken into forks, glacial gradients, lacquers, often only limited information is kept and, after model-by-frame completion, visible fine texture is presented on the 8K curtain.
Secondly, the edges are rebuilt. In the scenes of the scenes, the images are magnified and exposed to the problems of edge stitches, contours and texture fractures. In response, the Al MediaKit superscore programme further optimized the detailed performance of key areas and allowed for more natural and stable clarity in viewing the screen.
Third, time-series consistency guarantees. Videos are not static images, and the "jumping" between successive frames is the invisible killer of ultra-point technology. If each frame is handled independently, the image may be scintillated, texture drifted. The mega-scene hyperscene programme introduced time-series binding mechanisms to ensure consistency in the texture of completion and to smooth the screen as silk.
The 20-metre-scale screen needs to be supported by real pixel density, with a long view of power and near details.
The presence of both stage light, motion pictures and large-scale screens is more important for stability.
The image must not only be sharpened, but also natural, clean and continuous.
High resolution masters keep the screen layered and do not appear loose by magnifying the size.
In complex light and fast motion, clarity, stability and natural sense need to be established simultaneously.
AI MediaKit, the engineering of a giant scene. Land
On the night of 2026 Douyin, the Volcengine AI MediaKit superspection program was used mainly to play the graphic enhancement of asset, allowing 720 P/1080P to reach the ultra-high resolutiones that fit the screen. At the same time, the accompanying increase in colour and dark detail has also helped to further enhance the overall view of the picture in the scene. Volcengine has now supported a maximum of 16 bit full-scale depth output, which can significantly improve the colour transition and detail of the large screen. In the end, the enhanced processing of asset shows a clearer, more stable and more complete visual effect on the scene.
For such projects, the difficulty lies not only in the qualitative enhancement itself, but also in the ability to achieve steady delivery within a limited production cycle. Volcengine, with its super-large video processing capacity accumulated in the long short video operation, sharpened the graphic enhancement chain from low resolution to 8K to engineering level to ensure that every programme was in the best position to go on screen. Moreover, the technical ceiling of the package is much more than that, and the maximum support is for increasing the picture to 16K/32K resolution, leaving sufficient technical space for a larger and more specific scenario in the future.
As AIGC content, AI-generated video applications become more common at parties and large events, the gap between the original assetresolution and terminal broadcast specifications only increases. Volcengine AI MediaKit, which is the kind of actual production problem that needs to be solved: Controlling production costs has helped to increase the number of asset screens and scene scenes and improve the quality of clarity, stability and perception that eventually emerge.
This capability is also more than a stage application. As early as the spring of 2026, Volcengine had boosted the 720P video generated by Seedance 2.0 to 8K, relying on the same amount of overrated power, and successfully made it onto the screen. Both stage performances, branded publish, and exhibition tours, history asset, common high-resolution asset and AIGCZ98Z can be better served by enhanced processing. As the display specifications continue to rise, it is also expected that the curtains will expand further to more scenes such as immersion space, digital art displays, commercial screens, urban public displays and large-scale events and events. In the future, the Volcengine smart video cloud will continue to use hard technical capabilities to provide reliable and stable Al MediaKit screen super-score solutions for more industry clients.
