http://www.maartenbaert.be/simplescreenrecorder/ my version only works with X11, not wayland though.

I took at look at this and had to try installing it on my Raspberry Pi. It worked great!

I couldn't get it to recognize my microphone but I didn't fiddle with that much. It was easy to capture an audio track on my Mac while recording the screen on the Pi and bring the movie over into Quicktime and sync them up.

I've been looking for a way to record the screen on my Pi so I thank you too!

This is a life saver, thanks for sharing.

I have recorded many hundreds of hours of content. I first used Quicktime on MacOS, it worked well enough. Great quality, fast, and easy to use.

More recently I moved over to OBS, which I consider to be far superior to Quicktime for one important reason: more control over audio settings. With OBS I can use just about any mic and get reasonable sound quality with a few tweaks. At present, I'm using a $20 headset and it works just fine.

OBS has been useful, so has Overwolf, but I think the best tool I've used has been Quicktime on OSX. It's much easier to use than most things. My go-to on Windows is the XBox Game DVR recording functionality but I only use it because the alternatives are pretty slow.

shareX for windows! Been using it for prob 10 years and its donate-ware

records in MPEG or GIF and lots of screenshot options as well. auto-upload to lots of free sharing sites if you choose. for screenshots I use Windows10 built-in "snipping tool" you dont get any simpler than that.

For simple recordings, I use https://screencast-o-matic.com

My answers are platform-specific:

For Windows: Camtasia

For macOS: Screenflow

Screenflow or Quicktime.
