What is HFR? Everything You Need to Know

HFR stands for High Frame Rate and is expressed with a well-known unit fps. You might have once heard about HFR from your friend or experienced it yourself while buying a security camera or watching a movie. The most common and widely used application for HFR is video, filming, and gaming.

In this article, we will explain what HFR is. We will talk about the most common frame rates and their advantages and applications.

What Is HFR?

HFR is a common term that refers to a high frame rate. The higher the frame rate, the better will be the visual graphics.

Higher frame rates enhance your visual experience by making the video smoother and lag-free. However, a frame rate is a measure of images displayed every second means a video with HFR has a larger file size, and LFR has a smaller file size.

In the older times, only standard frame rates were available up to 10-12 FPS. You can also visualize the low frame rates in vintage 90s movies like The Godfather. The trend evolved gradually from low frame rates to higher frame rates. You can see a quick transition in 2000s movies and games, which were upgraded to 120fps. Modern televisions support 4K and 8K, the top HFR.

The movies you watch today are shot with the best possible video equipment, and you can also change the resolutions according to your system requirements. The gaming industry has also adopted the HFR for high-quality visuals and smooth gaming experience. The common HFRs are 25fps, 48fps, 60fps, and 120fps, which you usually encounter daily.

Common HFR Rates

25fps

25fps is commonly used for video recordings and broadcastings. Some security cameras also have the option to record at this frame rate. It is a suitable frame rate for security cameras as it captures the required details and offers enough clarity. However, you might experience minimal lag, especially if the object is too fast.

48fps

48fps is advanced and smoother as compared to 25fps. It reduces the motion blur in videos and makes it appealing to watch. It brings more details to the video, so even if you see it in slow motion. It is also good for detecting the motion of objects more accurately. However, this frame rate is not quite common in security cameras. The standard for that is 25 to 30 fps.

60fps

60fps reduces the blurry motion effects and makes the footage smooth with quick actions no matter how fast the object is. HFR is a crucial aspect of competitive gaming to enjoy a lag-free experience. It is definitely a clear advantage, but it requires too much storage space and bandwidth. Plus, the cost of a 60fps camera will be way higher than the common security cameras.

120fps

120fps is a high-end choice. It is usually used in games and not expected in security cameras. You might have experienced 120fps in VR or AR or have a television that supports it. It has ultra-smooth motions that make the scene more exciting and real. But for special security, it could be a great option to even notice the license plate for a very fast moving vehicle.

Advantages of High Frame Rate

Better Video Quality

HFR provides a more detailed video because of the greater exchange of frames per second. There are more frames and images per second, so you have more information to look at. You can experience the video with sharper and more detailed graphics. The scenes will appear smoother and let you visualize the facial features and other details without any hassle.

Better Clarity in Slow Motion

When a security camera captures videos in slow motion, the video quality heavily depends on its frame rate. Lower frame rates do not have too many frames, which is the reason you experience lagging. For smooth video playback, even in slow motion, it is better to have high frame rates. It gives you optimal clarity and more information.

Reduced Motion Blur

Motion blur can ruin the footage when it comes to security cameras. It hides the details of the object and makes it difficult to identify. The best way to prevent motion blur is to increase the frame rate. It offers smoother playback and allows the camera to capture intricate details.

Application of High Frame Rate

Video and Film

Filmmakers and videographers prefer high frame rates because of fast-moving scenes. HFR assists them by providing clear and detailed footage. They are highly effective in action and fighting scenes. The current film production is mainly based on 120fps or higher to make it more engaging for the fans.

Sports

Sports broadcasts and slow-motion replays include HFR, which captures detailed and smooth actions. It enhances the graphics for the people watching live to enjoy the real experience from their homes. For instance, if a footballer scores a goal, you can only visualize it clearly if the broadcasting is done with HFR.

Virtual Reality (VR) and Augmented Reality (AR)

HFR helps you by providing high-quality graphics while wearing a VR headset to maximize comfortability. AR and VR need to sense motion more quickly and this can be done only with HFR. A higher frame rate controls the latency by reducing it to its lowest for a smooth experience.

Security and Surveillance

Security cameras need HFR to be as efficient to recognize a person even in darkness. Cameras like cx810 have HFR to produce a clearer image if the object or individual is moving at a fast pace. It improves the monitoring capability and provides responsive footage.

Gaming

Gaming is one of the most crucial things that needs HFR to make it more attractive and reality-based. Games that involve fighting and action need low latency for a competitive experience. The smoothness is a critical chunk that must be prioritized while gaming.

Industrial inspection

Industrial inspection needs accurate footage to pick up and replace the defect immediately. Sometimes, slow-motion playback is needed to inspect a machine at high speeds, which needs HFR monitoring.

FAQs

1. What is HFR gaming?

The common gaming HFRs are 120fps, 144fps, or higher, providing high-quality graphics for a smoother experience. Shooting games need more precision and reflexes, so a higher frame rate is required to meet the expectations.

2. What does HFR mean in news?

HFR in the news means broadcasting the same as when you watch live sports. A higher frame rate keeps the footage lag-free and allows users to watch it on television without any blur or delay.

3. How does HFR work?

HFR is the number of frames displayed per second. For instance, you have a 60fps display; the suffix 60 represents the number of frames/second. The higher the frame rate, the better the video quality.

Conclusion

Eventually, the world of HFR is increasing in terms of technology and providing more options for the users to choose according to their system needs. You can experience HFR almost everywhere, even in your eyes. It helps you to approach a more detailed and enhanced quality.
