What Are REC 709 and REC 2020?
Understanding REC 709
REC 709, also known as BT.709, is a color space established by the International Telecommunication Union (ITU) in 1990 for HDTV standards. It defines parameters such as:
- Color gamut: Covers approximately 35.9% of the visible color spectrum.
- Gamma: Uses a 2.4 gamma curve, optimizing contrast for broadcast and HD content.
- Bit depth: Supports 8-bit per channel, providing 16.78 million colors.
- Use cases: Commonly used in TV broadcasting, YouTube videos, Blu-ray discs, and streaming platforms like Netflix and Amazon Prime Video.
REC 709 ensures consistent color reproduction across different devices, making it the preferred standard for SDR (Standard Dynamic Range) content. However, its limited color gamut and dynamic range make it less suitable for HDR and next-generation display technologies.

Exploring REC 2020
REC 2020 (BT.2020) was introduced in 2012 to accommodate the growing demand for 4K and 8K UHD content. Compared to REC 709, it offers a significantly wider color gamut and better color accuracy, making it ideal for HDR workflows.
Key features of REC 2020 include:
- Color gamut: Covers 75.8% of the visible spectrum, enabling richer and more vibrant colors.
- Bit depth: Supports 10-bit and 12-bit color depth, offering over a billion color variations.
- Use cases: Used in HDR content, professional filmmaking, high-end gaming, and next-gen display technologies like OLED and QLED TVs.
Despite its advantages, REC 2020 adoption remains a challenge due to limited hardware support. Many consumer-grade displays and editing software still rely on REC 709, requiring conversion tools to bridge the gap between the two color spaces.

Key Differences Between REC 2020 and REC 709
REC 2020 vs REC 709: A Detailed Comparison
When comparing REC 2020 vs REC 709, the most significant difference lies in their color gamut.
Color Gamut: REC 709 covers approximately 35.9% of the visible spectrum, whereas REC 2020 covers 75.8%, allowing for a much wider range of colors.
Bit Depth: REC 709 supports 8-bit color depth, displaying 16.78 million colors. REC 2020, on the other hand, supports 10-bit and 12-bit color, producing over a billion colors for greater precision.
Gamma Curve: REC 709 uses a 2.4 gamma curve, optimized for SDR content. REC 2020 features more advanced gamma curves tailored for HDR workflows.
HDR Support: REC 709 does not natively support HDR, while REC 2020 is fully optimized for HDR, enhancing contrast and dynamic range.
Device Compatibility: REC 709 is widely supported across HDTVs, monitors, and SDR content. REC 2020 requires specialized HDR-compatible displays for full-color accuracy.
Color Gamut & Bit Depth
REC 709 has a smaller color range, meaning it cannot accurately reproduce many vibrant shades, especially deep reds, greens, and blues. On the other hand, REC 2020 nearly doubles the range of visible colors, making it better suited for HDR content, professional video editing, and high-end display technologies.
HDR & Dynamic Range
Since REC 709 was designed for Standard Dynamic Range (SDR) content, it lacks the expanded contrast levels required for HDR10, Dolby Vision, and HLG formats. REC 2020, however, supports HDR workflows, allowing for richer blacks, brighter highlights, and an overall more lifelike image.

Applications of REC 2020 and REC 709
When to Use REC 709
Despite its limitations, REC 709 remains widely used across various industries due to its compatibility with HDTVs, computer monitors, and streaming services. It is ideal for:
- Broadcast television (e.g., news, talk shows, traditional TV content)
- YouTube, Vimeo, and other SDR video platforms
- Blu-ray and DVD production
- Legacy systems that don’t support HDR
- Live streaming and fast-paced video editing workflows
Since most consumer displays are calibrated for REC 709, it remains the most reliable and practical choice for everyday content.
Why Choose REC 2020?
REC 2020 is the future of display technology, offering higher color accuracy and HDR support. It is best for:
- Filmmaking and high-end video production
- HDR content for Netflix, Amazon Prime, Disney+, and other streaming services
- 4K and 8K resolution workflows
- Professional color grading and post-production
- Advanced display technologies (OLED, QLED, HDR monitors, and projectors)
With HDR and 8K displays becoming more mainstream, REC 2020 is gradually replacing REC 709 as the standard for modern digital content.
Challenges and Considerations
Limitations of REC 709
While REC 709 has been the industry standard for decades, it comes with several limitations:
- Narrow Color Gamut: REC 709 cannot reproduce many highly saturated colors, leading to less vibrant images compared to REC 2020.
- Limited Dynamic Range: Since REC 709 is optimized for SDR, it does not take advantage of HDR capabilities, resulting in less contrast and detail in shadows and highlights.
- Outdated for Modern Displays: With the rise of 4K HDR, OLED, and QLED displays, REC 709 is slowly being replaced in professional workflows.
Despite these drawbacks, REC 709 remains widely used due to its compatibility with most consumer displays.
Challenges with REC 2020
Although REC 2020 offers superior color accuracy and HDR support, it also has its challenges:
- Limited Hardware Support: Most consumer-grade monitors, TVs, and projectors do not fully support REC 2020, requiring downscaling to REC 709.
- Higher Production Costs: Creating true REC 2020 content requires HDR-capable cameras, displays, and advanced color grading workflows, which can be expensive.
- Complex Workflow Adjustments: Editors and colorists must ensure their software and hardware are calibrated correctly, as improper handling can lead to color inaccuracies.
Despite these challenges, REC 2020 is essential for high-end video production and future-proofing content for emerging display technologies.
Practical Tips for Implementation
How to Transition from REC 709 to REC 2020
If you’re working with REC 709 but want to upgrade to REC 2020, follow these steps:
- Use a Color-Accurate Monitor – Invest in HDR-compatible displays that support REC 2020 for accurate color grading.
- Adjust Camera Settings – If your camera supports REC 2020 or Log formats, enable these settings for better color retention.
- Apply LUTs for Conversion – Use Look-Up Tables (LUTs) to convert REC 709 footage to REC 2020 while preserving color accuracy.
- Use Professional Editing Software – Programs like DaVinci Resolve, Adobe Premiere Pro, and Final Cut Pro offer tools for REC 2020 color grading.
- Test on Different Displays – Since not all screens display REC 2020 correctly, always check how your footage looks on HDR and SDR displays.
- Calibration is Key – Even with a high-end display, calibrating your monitor ensures accurate color representation. Tools like X-Rite i1Display Pro or CalMAN software help achieve professional results.
