Shrinking Your Videos Without Losing Quality: The x265 Compression Guide
Performance Scaling (1080p Source):
| Preset | Relative Speed | Bitrate Increase (vs slow) |
| :--- | :--- | :--- |
| veryslow | 1x (Baseline) | -5% (Smallest output) |
| medium | ~3.5x | +5% |
| fast | ~10x | +15% |
| superfast | ~25x | +35% (Largest output) | shrinking x265
If you have a hard drive screaming for mercy, download a tool like HandBrake, select "H.265," and watch the gigabytes free up. Shrinking Your Videos Without Losing Quality: The x265
The "standard" balance for good quality at a significantly reduced size. 4K (UHD) Content: You can push the CRF higher, up to , without noticeable loss due to the high pixel density. Rule of Thumb: Every increase of roughly halves the resulting bitrate/file size. 2. Encoder Presets: Slow is Small Rule of Thumb: Every increase of roughly halves
How did we get here, and what’s being lost in the compression?
The next time you download a 1.5GB x265 “1080p” movie, ask yourself: Are you saving space, or are you watching a ghost of the original?
