I have found that using OctoPrint, when it come to 3D Printing you need to print at a slower rate.
I know that when I use the OctoLapse plugin it causes problems see image below.
Model Printed with ABS @ 236C Hot-end 96C Bed
Left model printed with OctoLapse right directly from Controller onboard SD Card.
Because of problems using OctoPrint, now only print with controller SD card. However I still use OctoPrint to monitor the Printing from another Room.
It would be nice If while monitoring I could Record the video stream from OctoPrint though. I would like to purchase a new Raspberry Pi 4 to test OctoPrint / OctoLapse.
Have wondered if the faster Raspberry Pi 4 would allow OctoPrint / OctoLapse to print at a faster rate allowing for a better 3D printed model.

I use an old cell phone to monitor prints once in a while. There are free apps that make it super easy and don't require any subscriptions. Get OpenCamera - it lets you set up shots at a specified interval and resolution. Save the images in a directory on the phone that is backed up automatically by google photos. My old Droid Turbo has a 28 Mp camera, so I can get very high resolution images. I can check print progress by opening google photos via any web browser- the images get backed up the instant they are shot. I can also take all those images and use them to make timelapse movies. I start by batch cropping and scaling the images to whatever video resolution I want using irfanview (free), then make a movie from the sequence using imageJ (free).
Octoprint generates all sorts of wonderful stats if you're into that sort of thing, and allows you to start and stop prints using your phone (assuming the right filament is already loaded, the bed is clean, etc.) which might really impress your low-tech friends. The only value octoprint would have for me is stopping a failed print, but that happens so infrequently it wouldn't be worth the trouble to set up and maintain Octoprint. Then there are problems like stuttering prints... RPi cameras are a joke compared to my old cell phone camera.
Here's an image from the cell phone running Open Camera (click on it to see the full resolution image):
Open camera lets you add the text labeling with the time, etc., or turn that off if you don't want it.
There's more info and a sample time-lapse video on my blog. I can't figure out how to link the video here.
I mount the phone on the printer using a couple suction cups attached to a bent aluminum bracket that took about 20 minutes to make using hand tools. The camera attaches to the bracket with velcro tape.
