StudioScreenRecorder

StudioScreenRecorder is a Windows desktop screen recorder built with Python, customtkinter, FFmpeg, SoundCard, NumPy, and SciPy. It combines smooth desktop capture with synchronized system loopback audio, microphone recording, live audio cleanup, and recoverable MP4 output in one easy-to-use application.

Features

• Records the Windows desktop at a target rate of 60 FPS using FFmpeg gdigrab
• Captures system audio through the active speaker's loopback device
• Captures and mixes microphone audio alongside system sound
• Applies low-frequency rumble removal and smooth audio block transitions
• Detects default audio-device changes and reconnects during recording
• Writes fragmented MP4 data continuously for improved crash resilience
• Finalizes completed recordings into standard, player-friendly MP4 files
• Provides a responsive desktop interface with recording and folder controls
• Includes direct links to official downloads, source code, and author profiles

How It Works

The recording engine launches FFmpeg as a background process for desktop video capture and encoding. Separate audio workers collect system and microphone samples, normalize their channel layout, smooth discontinuities, and feed a synchronized mixed stream into FFmpeg. Queue limits and missing-block concealment help the application remain responsive when Windows audio devices briefly pause or change.

During capture, output is written as a fragmented MP4 so useful recording data is preserved progressively. When recording stops normally, StudioScreenRecorder remuxes that file into a standard MP4 with fast-start metadata for broad media player compatibility.

Installation

Install from PyPI:

pip install studioscreenrecorder

Run

After installation:

studioscreenrecorder

Choose a destination folder, enable the capture sources you need, and select START. Select STOP to finalize and save the recording.
