I do not know what "then 4d means(h,w,b,f) is or not.." means. Please explain. With read() you can read a frame from a video, or the whole video, which would be a 4D array if you had a color video.

Is is a whole video not frame..

Each frame of a video is represented by a 3D array -- height, width, and color channel (R, G, B). You can store multiple frames in the same array by using the 4th dimension, making the array height, width, channel, frames
IM(13,5,2,14)
is frame 14, channel 2 (Green), pixel row 13, pixel column 5.
