Large video files can be a real headache—consuming hard‑drive space, lengthening upload times, and turning off online viewers. Whether you’re sharing on social media, embedding in blogs, or emailing, you need a tool that shrinks files without compromising quality.
What Drives Video File Size?
Beyond resolution, four key factors determine a video’s physical size: bitrate, frame rate, encoding format, and the container format. Understanding these will help you choose the right settings for the best balance of quality and compression.
| Quality | Resolution | Aspect Ratio | Typical Bitrate (Mbps) |
|---|---|---|---|
| 8K (4320p) | 7680 × 4320 | 16:9 | >50 |
| 4K (2160p) | 3840 × 2160 | 16:9 | 25‑30 |
| QHD (1440p) | 2560 × 1440 | 16:9 | 15‑20 |
| Full HD (1080p) | 1920 × 1080 | 16:9 | 8 |
| HD (720p) | 1280 × 720 | 16:9 | 5 |
| SD (480p) | 852 × 480 | 16:9 | 2‑3 |
For most online applications, scaling down to 1080p or 720p offers the best compromise—high‑resolution enough for clear playback yet small enough for quick sharing.
Recommended Compression Profile
- Container: MP4 (universally supported)
- Resolution: 1080p or 720p
- Bitrate: 8 Mbps for 1080p, 5 Mbps for 720p
- Frame Rate: 24–30 FPS
- Codec: H.265 (offers 25–50% better compression than H.264 at comparable quality)
