Effective Ways to Compress OBS Studio Recordings Easily
Last updated: May 2026
Understanding OBS File Sizes
OBS Studio is a popular choice among creators for recording and streaming, but the resulting files can be hefty. This is due to OBS recording videos in high quality by default, leading to large file sizes.
By understanding the factors that contribute to file size, such as bitrate, resolution, and frame rate, you can make informed decisions about how to compress your recordings.
Adjusting OBS Settings for Smaller File Sizes
Before starting your recording, tweak OBS settings to create smaller files without significantly sacrificing quality:
- Resolution: Lowering the resolution can greatly reduce file size. Consider recording in 720p instead of 1080p if high definition isn't necessary.
- Bitrate: Adjust the video bitrate to a lower setting. A bitrate of 2500 kbps is often a good balance between quality and size.
- Frame Rate: Reducing the frame rate from 60fps to 30fps can decrease file size while maintaining acceptable quality for most recordings.
Using Video Compression Software
Post-recording, you can use video compression tools to further reduce file size. Popular options include:
- HandBrake: A free, open-source tool that allows you to compress and convert video files efficiently.
- FFmpeg: A command-line tool that provides powerful options for video compression and conversion.

Archiving and Storage Solutions
Once you've compressed your OBS recordings, consider archiving to save space. Options include:
- Cloud Storage: Utilize services like Google Drive or Dropbox for easy access and sharing.
- External Hard Drives: Invest in physical storage for long-term backup and security.
