Hello djkam2001,
We see that you have questions about Quicktime and screen recording.
When you first open Quicktime it’s expected to show the “Open File…” window. If you close the window and click File > New Screen Recording you should still be able to record your screen and the video should be saved after stopping the recording.
When you start a new screen recording, you should see the Screenshot toolbar. If you click the Options dropdown you can choose where the screen recording will be saved.
To stop recording, click the stop icon in the menu bar. If you quit Quicktime without stopping the recording it will not be saved.
Keep in mind, you don't have to open Quicktime to start a screen recording, you can press Shift + Command + 5. That will bring up the Screenshot toolbar where you start a screen recording. How to record the screen on your Mac
We hope that helps.
