Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"


Hi, 我尝试使用sequencer输出视频。使用cinematic摄影机,200%屏幕尺寸,2560x1440分辨率下一切顺利。 但是当我选择用3840x2160分辨率进行输出时,无论100%还是200%屏幕尺寸,都会发生错误。其中100% 4K输出时,似乎抗锯齿过程(TAA)被一并输出了,所以画面显得很模糊而且撕裂。而200% 4K输出时,sequencer直接崩溃,输出失败。

我使用的显卡 是GTX 1080 8G, 内存 64G。

参考输出结果请参考这个连接: 链接:https://pan.baidu.com/s/1xYZF7vTdtrO9KBUSVZVN1A 提取码:9l3j

此外,当我使用Quadro P6000和Gefore GTX 1080分别用sequencer制作动画时,我注意到GTX会直接在屏幕上新建一个目标输出分辨率的窗口(如4k)来进行计算,由于显示器小于4K,因而这个窗口会占用超出一个屏幕。 而Quadro无论输出多大分辨率,在计算过程中,屏幕上都只有一个1000像素左右的小窗口在进行渲染,不占用屏幕,而且看上去稳定性要好得多。这是有目的设计的功能特性吗?

Hi Fisher, 从视频上暂时无法判断具体是哪里的原因,可以提供下崩溃时候的log和dump吗,他们一般存在项目文件夹下的Save文件夹下。
