A simple yet fast and nimble screen capture application coded in python using pymovie and ffmpeg to capture your screen and any audio on your system then create an mp4 file of your specified length. grabber.py was used to make this video in conjunction with Kdenlive, on linux mint. It was recorded into 7, 3min long clips of 30mb each. you can see the application running and doing its thing
a few mistakes were made in the making of the code video such as indentation errors in the ffmpeg_cmd sub routine. I have included the correct code below and please customize and use it for your own stuff.

import os
import time
import subprocess
import pyautogui
from moviepy.editor import *

def record_screen_with_audio(duration=10, output_filename="output.mp4"):
screen_width, screen_height = pyautogui.size()

original_mouse_position = pyautogui.position()

pyautogui.moveTo(0, 0)

temp_file = "temp.mp4"

ffmpeg_cmd = (
f"ffmpeg -y -f x11grab -s {screen_width}x{screen_height} -i :0.0 "
f"-f alsa -ac 2 -i default -t {duration} -c:v libx264 -c:a aac -strict experimental -r 30 {temp_file}"
)
subprocess.Popen(ffmpeg_cmd, shell=True)

time.sleep(duration)

pyautogui.moveTo(original_mouse_position.x, original_mouse_position.y)

video_clip = VideoFileClip(temp_file)
video_clip.write_videofile(output_filename)
video_clip.close()
os.remove(temp_file)

if _name_ == "__main__":
record_duration = 180
output_filename = "captured_video.mp4"
record_screen_with_audio(duration=record_duration, output_filename=output_filename)
