Can I record Samsung DeX on a Mac?

Yes. If DeX runs in a Mac window through scrcpy, add --record=file.mp4 to save the session as a video. Deskbridge Pro does the same with a menu toggle.

Why is my recording unplayable?

The MP4 is finished when scrcpy exits normally. Stop it with Ctrl+C or by closing the window; if the process is killed, the file can be left without its index.

Does recording include sound?

It includes phone audio when audio is on and your phone supports audio forwarding; with audio off the video is silent.

How to record Samsung DeX on a Mac

When DeX runs in a Mac window through scrcpy, add --record=dex.mp4 and the whole session is saved as a video. Stop with Ctrl+C so the file is finished properly. Deskbridge Pro does the same with one menu toggle.

Free: scrcpy in Terminal

If you already run DeX with scrcpy (setup guide), add one option:

scrcpy --new-display=1920x1080/240 --record=dex.mp4

The file appears in the folder you ran the command from. Use a .mkv name instead if you'd rather have a format that survives a crash (QuickTime can't open MKV; VLC and IINA can).
Stop with Ctrl+C in Terminal or by closing the window. scrcpy writes the MP4's index when it exits normally; if the process is killed, the MP4 can be left unplayable.
On some phones the default H.265 encoder fails; add --video-codec=h264.

One click: Deskbridge Pro

With Deskbridge Pro ($5 a year on top of a Deskbridge license), turn on Record Desktop to Movies in the menu. Every DeX session is saved to Movies › Deskbridge, named by date and time, and Deskbridge asks scrcpy to stop cleanly so the file gets finished. Recording is in beta.

Record DeX without Terminal

Deskbridge opens DeX in a Mac window when you plug in. Free for 7 days, then $12 once; Pro is $5 a year on top.
