Before jumping from the SDR to HDR converter for any video upgrade, you must have clarity about HDR, how it is different from HDR, why you need HDR, and many other factors. Once you have a brief idea about what and why you are heading to, it's time to pick the most powerful SDR to HDR converters to upscale the video quality as per your requirements. Here, you will get an overall idea about SDR to HDR with three prominent SDR to HDR converters.
What is SDR and HDR
Before heading to SDR or HDR, let's clarify that SDR and HDR are different from SD and HD.
Difference Between HD and SD: SD (Standard Definition) refers to the resolution that involves the number of pixels in a specific dimension of a display monitor. In contrast, HD (High Definition) emerged with the transition from analog to digital, offering higher resolution and greater pixel density than SD, which was equivalent to analog display quality.
SDR vs HDR: SDR (Standard Dynamic range) is more of a video technology that refers to the intensity of the brightness, color, and contrast of light and shadow. HDR (High-Dynamic Range), on the other hand, offers superior video quality compared to SDR, focusing on a broader range of colors and improved brightness and contrast. HDR enhances the visual experience by leveraging the high color range present in HD displays. Without HD, HDR wouldn't exist.
Understanding these differences helps in appreciating the technological advancements in video quality.
Why do you should convert SDR to HDR?
SDR and HDR are two video technology that tackle color clarity, exposures, light effects, detailed information of the image, and balancing light & shade. As the name suggests, HDR is the advanced version of the Standard one. When SDR is used in basic camera and video display devices, HDR is used in advanced display devices like smart TVs, smartphones, monitors, and digital equipment. So, let's see the parameters that will help you understand why you need convert SDR to HDR.
- • Balancing Color & Contrast
SDR refers to a limited color gamut & range with under-exposure brightness & contrast. HDR involves better exposure, color, brightness, and detailing of any video with dynamic color vibrancy and enhanced light & dark objects. HDR also adds 3D effects to any video.
- • Brightness & Dynamic Range
- In the SDR display devices, the brightness range occurs between 100 to 300 bits & the dynamic range is about 6 stops. In HDR, the brightness range could be adjusted between 1 nit to 1000 nits on scenes with a dynamic range of 17.6 stops.
- • Color Depth & Gamut
In SDR, the color depth range is from 8 to a maximum of 10 bits, and the color gamut range is Rec.709. In HDR, it is extended from 8 up to 12, and the color gamut range is Rec.2020.
- • File Size Support
SDR can't handle complex data with a huge file size. In contrast, HDR tackles large file sizes with more exposure and color detailing to add realistic appeal to any video. HDR also gives clarity to more visual detail in dark and bright areas in any video as compared to SDR.
- • Device Compatibility
To match the advanced technology in the digital media industry, most of the device displays are compatible with HDR video rather than SDR. No HDR-supported display wouldn't be able to give you HDR visual satisfaction with SDR-quality video.
