How to Use OBS Studio to Record Your Screen (Complete Tutorial)

Unlike simple recorders, **OBS Studio** (Open Broadcaster Software) offers total control. It allows you to separate your microphone audio from the game audio, create scenes with a webcam, and most importantly: use your graphics card's chip to record without losing FPS in the game. In 2026, it remains the most powerful and free tool for content creators.

Go to Settings > Output and change the Output Mode to 'Advanced':

• Type: Standard.
• Recording Path: Choose a folder on a fast SSD.
• Recording Format: Use MKV. If your PC crashes or the power goes out, you won't lose the video. Later, you can convert to MP4 within OBS itself (File > Remux Recordings).
• Encoder: Select your graphics card's encoder (NVIDIA NVENC H.264/AV1 or AMD HW). This takes the load off your processor.

Game Capture: This is the most efficient mode. OBS "locks" onto the game and nothing else appears, preserving your privacy (Windows notifications won't show in the video).

Display Capture: Use this only for tutorials where you need to show the entire Windows desktop. In 2026, this mode still consumes slightly more system resources than direct game capture.

Using scripts to automate repetitive tasks in OBS Studio:

💻 Advanced Script Example

Python script for automatic quality monitoring and adjustment:

import obspython as obs
import psutil
import time

def check_system_resources():
    # Obtain performance information
    cpu_percent = psutil.cpu_percent(interval=1)
    memory = psutil.virtual_memory()
    
    # Check if there are enough resources for recording
    if cpu_percent > 85 or memory.percent > 85:
        # Reduce recording quality
        settings = obs.obs_data_create()
        obs.obs_data_set_string(settings, "encoder", "nvenc")
        obs.obs_data_set_int(settings, "bitrate", 3500)  # Reduce bitrate
        obs.obs_data_set_string(settings, "rate_control", "CBR")
        
        # Apply encoding settings
        output = obs.obs_frontend_get_recording_output()
        obs.obs_output_update(output, settings)
        
        obs.script_log(obs.LOG_WARNING, f"Critical resources detected: CPU {cpu_percent}%, RAM {memory.percent}% - Reducing recording quality")
        
        # Release objects
        obs.obs_data_release(settings)
        obs.obs_output_release(output)

# Timer to check every 5 seconds
timer_active = False

def timer_callback():
    check_system_resources()

def start_timer():
    global timer_active
    if not timer_active:
        obs.timer_add(timer_callback, 5000)  # Every 5 seconds
        timer_active = True

def stop_timer():
    global timer_active
    if timer_active:
        obs.timer_remove(timer_callback)
        timer_active = False

# Auto-start timer on script load
start_timer()
