Movie Clip ,Open 1 moive capture from iphone 4K,240Frames total only ,30FPS,only 8seconds.
Click Prefetch, Play the movie FPS 24(Its fine)
2.Track motion the moive,Play the movie FPS 24(Its fine)
3.Set the floor,etc.
When Click “Setup as Background” and "Setup tracking scene " in the 3D Viewpoint,Press “0” The camera perspective
Then the movie clip become extrem slow only FPS 2~3,almost can not move ahead. Even you can not pull the timeline because the blender will no respond.
Only in User Perspective recover FPS 24, but you can not see the movie clip as background its hard to make the animation now.
Any one can save me ?It waste lots of time and almost cannot composite the 3D models at all.
Increase the blender system DRAM to 16GB (AMD 8Core,Nv 1070) even the Proxy 25% quality. But the play FPS only several frame.
When set moive clip as background it become even more slower. Almost can not drag the timeline ,super lag.
Look into proxying your images prior to adding to the viewport. Resize your sequence in another Blender session via the Sequence editor.
Your issue is most likely the drive IO or at least it is one of the issues you have. In that case you can try creating a RAM drive and try loading your sequence from a RAM drive, but that means that you need to have alot of free RAM.
I’m using the 1080P taken from iphone only 45MB file now but still the same slow. Dont understand why blender is hard to deal the video.
I create the RAMDISK and put the clip in the disk.The FPS still only 3~4.
Video Sequencer to resize how much? 720P?
