Snagit does not support GlF or MP4 files withdimensions greater than 3840x2160 or less than 64x64

今天用Snagit想截取屏操作为Gif，保存时提示：

Cannot open file.Snagit does not support GlF or MP4 files withdimensions greater than 3840x2160 or less than 64x64.

解决方法: 

 

打开注册表，查到：
HKEY_CURRENT_USER\Software\TechSmith\Features\snagit.

修改AllowHwVideoEncoding键值为0

 

然后重新启动Snagit
