The screenRecord limatation was increased from 3 minutes to 30 minutes in Android 14: https://cs.android.com/android-studio/platform/tools/adt/idea/+/30e0278da071829221e1282fff0381c175e38049

If you are running under rooted device you can apply this workaround to get more than 30 minutes, you can follow this tutorial : https://maestro.dev/blog/fixing-androids-3-minute-screen-recording-limitation

Or we can do the ugly solution by looping the screenrecord adb shell command and merge the frame later.
