I want to capture in low-light and have NoIR picamera.
I change the
off and set
import picamera with picamera.PiCamera() as camera: camera.resolution = (1280,960) camera.exposure_mode = 'off' camera.framerate =1 camera.shutter_speed = 6000000 camera.iso = 1600 camera.capture('dark.jpg')
The image I get is a decent one. I can see everything.
Now I do the same
resolution settings to record a
.h264 video. The video that I get is a black screen nothing else. Why is the video black but the image clear? Should I try the
raspivid commands to record video?
Also what is the relationship between
shutter_speed? I need fairly hight
framerate about 30 fps thus 1/30th a second is the maximum
shutter_speed possible ? Or can I increase
shutter_speed ? How can I achieve good recording while having a large
framerate at low light?
