Overview
Full HD, also called FHD or 1080p, refers to a video resolution with 1920 horizontal and 1080 vertical pixels. This results in approximately 2.1 megapixels per frame with a 16:9 aspect ratio. The "Full" designation distinguishes the format from the older "HD Ready" (720p) and indicates the full number of 1080 scan lines.
The appended "p" stands for "progressive" (full frame scanning): each scan line is built in one pass. This is in contrast to interlaced scanned 1080i, where a full frame is composed of two fields, each with 540 lines. Both share the same pixel count but differ in the scanning method; progressive images are considered cleaner with fast motion.
Technical Specifications
| Feature | Value |
|---|
| Resolution | 1920 × 1080 pixels |
| Total Pixels | approx. 2.1 megapixels |
| Aspect Ratio | 16:9 |
| Scanning | progressive (1080p) or interlaced (1080i) |
Common frame rates in production environments include 1080p24, 1080p25, and 1080p50, as well as the field formats 1080i50 and 1080i60. In post-production, 1080p24 is used as a digital mastering format, sometimes also in the 24PsF (progressive segmented frame) variant.
On-Set Usage
Full HD is the base resolution for professional HD workflows. Depending on the frame rate, different serial interfaces are used for signal transmission on set: HD-SDI for 1080i and 1080p25/30 signals, and 3G-SDI (or Dual-Link HD-SDI) for higher frame rates of 1080p50/60. The associated transmission standards (including SMPTE 372M and SMPTE 424M) typically operate in the YCbCr color space with 4:2:2 chroma subsampling.
Although cinema production today predominantly shoots and masters in 4K or higher, Full HD remains relevant: as a monitoring and preview resolution on set, in broadcast and streaming, and as a delivery and proxy format. Many on-set monitors, wireless transmission systems, and recording devices are designed for Full HD.
