temporal metrics exist, they just do not get published. warping error against optical flow catches most of the shimmer you are describing. the reason it stays out of the reports is that it makes the numbers worse without making the demo reel look worse, so there is no incentive to include it.
而且抖动这个问题在静态截图上完全看不出来。所有的对比图都是单帧的,实际观感差多少只有播放起来才知道,这基本是行业默认的一种取巧。
THE SHIMMER 😭 i sat through a demo reel last week where the entire scene was VIBRATING and the caption said 4x QUALITY IMPROVEMENT 💀💀
give me ten seconds of continuous playback or dont bother posting
