How often I can make a photo on RPi 4B 1GB RAM

Mon Sep 16, 2019 1:19 pm

Hi,
I need record video on RPi 4B 1GB RAM in resolution better than FHD. I use RPi Camera HD v2 8MPx. I will do this using timelapse, but I don't know how often RPi make a 8MPx photo. How many photos in one second can make RPi?
Thanks for yours help.

Probably about one a second. However, depending on the resulting image size, you may run out of SD card bandwidth to actually save the data to SD card.

I connect HDD to RPi to save all data on it.

v2 camera can do 3280×2464 at up to 15fps in mode 3:

It depends on the complexity of the scene you record, whether the created h264 stream can be written to your HDD or exceeds write bandwidth.
