I would like to save a series of 16 bits depth images to a video. I used VideoWriter but it only save video in 8 bits 3 channels. And I also check this linklink text, I don't know if it sopport 16 bits and single channel video write, or what can I do to save 16 bits single channel depth images as a video in C++? Can anyone help me ? Thanks for advanced.

you can write grayscale images by setting the last argument to VideoWriter to false, but it won't support 16bit images.

until you find a better idea, try to save a sequence of single 16bit images using imread() / imwrite()

EDIT:

if you have numbered 16bit images, like a0001.png, a0002.png, a0003.png you can use:

cap = VideoCapture("a0001.png") # start with 1st img number

and still retrieve 16bit images !
