python – How to write low quality video without anti-aliasing?

I have numpy array of grayscale pictures with shape (30,30).
The problem is that, when i write it with

cv2.VideoWriter(name + '.avi', cv2.VideoWriter_fourcc(*'FFV1'), fps=24, (30, 30), False)

or

skvideo.io.FFmpegWriter("test.avi", outputdict={'-vcodec': 'libx264', '-crf': '0','-preset':'veryslow'})

my squence of images becomes from that
raw picture with plt.imshow()

to that
picture from avi video file opened with vlc with h264 codec

So i want my video without any interpolation.

I know about resizing(for example cv2.INTER_NEAREST), but in this case it is not an option

How to write raw images in video fromat?
Does vlc player affects on video reading?
