Why is my YouTube Short blurry? Causes & fixes
Check whether YouTube has finished processing higher-quality renditions and which playback quality is selected. If the original is also blurry, inspect its resolution and export history before uploading another copy.
Check these first
- Check the selected YouTube playback quality after processing finishes
- Compare the same frame with the original at the same size
- Check whether softness exists before export
Likely causes
- Source resolution is lower than the platform displays it at
Upscaling a low-resolution source to fill a larger frame makes softness and blockiness more visible - this can contribute to softness even before any platform processing.
- The source was already heavily compressed
Re-compressing a file that has already been through lossy compression once (or several times, if it was re-shared) compounds the quality loss. The blur or blockiness may be baked in before this platform touches it.
Fix it
- Re-export from the original source
Rather than repairing a suspect file, export a fresh copy from the camera roll or editor and try that instead.
