How do I change resolutions?

[eagleseven007]

My USB Camera has always been jittery. I want to change the resolution. Online guides all reference "octopi.txt" but apparently that's not a thing anymore?

If you used octoprint_deploy you can change camera resolution by editing the camera environment file:
sudo nano /etc/cam_instancename.env

I'm fairly sure I used octoprint_deploy, but my camera environment file doesn't exist?

Much older versions just wrote it in the service file itself: sudo nano /etc/systemd/system/cam_instancename.service

Found it. Thank you.
