PC screen recordings made with OBS, Bandicam, or built-in recorders often look blurry and soft during playback, with unsharp text edges that hurt content delivery. With AI video repair technology now widespread in 2026, multiple mature solutions exist for fixing PC screen recordings. This guide is compiled by the Linghu Video Quality Restorer technical team using real test data, comparing 3 practical repair methods to help you choose the right one.
1. Common Causes of Blurry PC Screen Recordings
According to screen recording software user feedback, about 75% of PC screen recordings suffer from blurriness, mainly due to:
- Recording resolution mismatch: Recording area resolution is lower than the display's native resolution, becoming blurry when upscaled.
- Bitrate set too low: Reducing bitrate to shrink file size causes detail loss and blocky artifacts.
- Poor encoder choice: Using outdated encoders or hardware encoders with compatibility issues reduces sharpness.
- Scaling algorithm loss: Resizing operations during post-editing introduce interpolation loss, blurring text edges.
