What Is Rec.709?

Rec. 709 is a standard developed by the International Telecommunication Union (ITU) for high-definition television (HDTV). It defines the following:

1. Color Space: Specifies the color primaries, white point (D65), and transfer characteristics (gamma curve) used for HDTV.
2. Resolution: Typically associated with 720p and 1080p video formats.
3. Frame Rates: Supports various frame rates like 24, 25, 30, 50, and 60 frames per second.

Rec. 709 is widely used for HD broadcasting and production, ensuring consistency in color reproduction across different devices and platforms.
