What Do Video Resolution Numbers Really Mean?
Video resolution refers to the number of distinct pixels displayed on the screen. Higher pixel counts mean sharper images, but also dramatically larger file sizes.
| Resolution | Pixel Dimensions | Typical Bitrate | Best For | |---|---|---|---| | **720p (HD)** | 1280 × 720 | 2.5 - 4 Mbps | Mobile screens, saving data | | **1080p (Full HD)** | 1920 × 1080 | 5 - 8 Mbps | Laptops, TVs, crisp social media clips | | **1440p (2K QHD)** | 2560 × 1440 | 10 - 15 Mbps | High-end monitors, tablets | | **2160p (4K UHD)** | 3840 × 2160 | 20 - 45 Mbps | Ultra-wide monitors, video editing |
How to Choose the Right File Size - **Limited Storage or Mobile Data:** 720p provides a great balance between crispness and a compact 20MB-50MB file size. - **Standard Archiving:** 1080p Full HD is the golden standard for smooth playback, vibrant colors, and optimal compatibility. - **Short-form Vertical Content (9:16):** Most TikToks and Instagram Reels are recorded in 1080 × 1920, making 1080p the exact native format to preserve full clarity.
