Gphoto2佳能将电影录制质量的设置从HD更改为4K

Question

我想把佳能数码单反相机的设置从高清改为4K，反之亦然。我用gphoto2，libghot2来控制设置并捕捉照片和视频。（我已将nob切换到摄像机上的视频模式）

相机型号：佳能EOS 5D Mark IV

摄像头上的摄像头设置如下所示：

Movie Record Quality
 - MOV/MP4 
 - Movie rec. size  (MP4)
   -- FHD 50.00P IPB
   -- FHD 25.00P IPB
   -- FHD 25.00P IPB (Light)

 - Movie rec. size  (MOV)
   -- 4K 25.00P MJPG
   -- FHD 50.00P ALL-I
   -- FHD 50.00P IPB
   -- FHD 25.00P ALL-I
   -- FHD 25.00P IPB

gphoto2 --list-all-config没有列出这些设置。有没有办法我可以用脚本来切换这些。在
