+# Screen Recorder
+## Aim 
+To build a screen recorder using Python pyautogui.
+## Purpose
+Screen Recorder is a software used to record your screen and saves it as a video file.
+## Short description
+- This code enables us to record screen easily.
+- Recorded file will be saved as "Recording.avi"
+- Libraries imported :
+    - `pyautogui`
+    -  `CV2`
+    -   `numpy`
+
+## Workflow
+- Imported required libraries i.e.,`pyautogui`,`CV2`,`numpy`.
+- Resolution is set to 1920x1080.
+- Framerate is set to 60.0 mps.
+- Created a video object and an empty window, resized this window and named it as LIVE.
+- PyautoGUI is used to take screenshots.
+- numpy will convert those screenshots into an array.
+## Compilation Steps
+- Download the file [screen_recorder.py](https://github.com/tanujadasari/Awesome_Python_Scripts/blob/main/GUIScripts/Screen%20Recorder/screen_recorder.py)
+- Run the file [screen_recorder.py](https://github.com/tanujadasari/Awesome_Python_Scripts/blob/main/GUIScripts/Screen%20Recorder/screen_recorder.py), let's start recording our screen.
+- Install pyautogui, CV2, numpy if you don't have them.
+- After clicking run,it takes continuous screenshots and makes it into an array, out.write will convert this as a video.
+- The screen will continue to record until we press `q`
+- Finally, recorded file will be saved as "Recording.avi".
