How to Record MP4 Videos in OBS Flawlessly


  • More compatible format for uploading and editing
  • Smaller file size
  • Prone to errors and corruption if recording stops unexpectedly


  • More stable format for recording
  • Larger file size
  • Needs remuxing to MP4 for editing and sharing

Best Practices

  • Use “Automatically Remux to MP4” setting to record MKV and automatically convert to MP4
  • Ensure system has enough processing power and disk space
  • Use recommended encoder settings like CRF rate control
  • Set keyframe interval to 2 seconds
  • Record separate audio at 48kHz sample rate

Optimized Settings

  • Output Mode: Simple
  • Recording Quality: Indistinguishable Quality
  • Encoder: Hardware encoder if available
  • Container Format: MP4
  • Video Bitrate: 4000-6000 kbps at 1080p60
  • Keyframe Interval: 2 seconds
  • Audio Sample Rate: 48kHz


  • Update OBS and graphics drivers
  • Close other resource intensive programs
  • Use log analyzer to diagnose issues
  • Record short test clips to check settings
  • Revert to last known good OBS version if update causes issues

In summary, recording to MP4 directly has some risks but can be done smoothly by optimizing OBS settings, system resources, and following best practices like automatic remuxing. Testing different configurations is key to balancing quality and performance.
