ESP32 CAM: How To Save Movies On An SD Card

Here’s a tutorial that shows you how to record a movie using the ESP32 CAM microcontroller module and save it onto an SD card. I’ve used the ESP32-CAM-Video-Recorder-junior example project. It records a series of short movies in .AVI format onto the ESP32 CAM’s SD card. It doesn’t need a wifi connection so you can use it anywhere.

The ESP32 CAM module has an integrated Micro SD card slot. Personally I use 4 Gb cards with my camera modules, but apparently cards as large as 16 Gb work too.

If you’re wondering what the image quality is like, here’s a cinematic style movie I recorded using the ESP32 CAM module with the popular OV2640 fisheye lens. The lens has a 160° field of view and is really nice considering it’s so small.

In the above video I discuss some of the various issues with taking movies, including the notorious green tint, the lack of a viewfinder and some strange quirks I found while recording the AVI files.
