Understanding Common FPS Values: The Advanced Guide to Video Frame Rates [2023 Update]
Without a doubt, live video streaming online and streaming video content online is more popular than ever. Over 85% of all internet users in the US alone watch online video content monthly. According to HubSpot, 91% of businesses regularly use video as a marketing tool – an all-time high. Businesses, broadcasters, and aspiring individuals who aren’t creating content may be missing out on a lot of traction and opportunities.
Demand for video continues to rise, and it’s a fantastic video tool that will remain attractive and lucrative to businesses. But many broadcasters are intimidated by video industry jargon such as FPS video, multiple frame rates, picture resolution and so forth. However, the technical jargon need not impede on your technical progress. With guidance, you can better understand the importance of FPS values and how best implement high-quality video to enhance your business online.
In this article, we’re going to delve deep into understanding common FPS values. We’re going to guide you on how to correctly use common FPS value to enhance your content and to create professional-looking videos that inspire your audience and play seamlessly across their screens. Using easy-to-read tables, we’ll give you expert recommendations on video settings, bitrate settings and more.
What is a Frame Rate?
What is a Frame Rate?
Video is a series of still images that, when viewed in order at a certain speed, give the appearance of motion. Frame rate refers to the number of individual frames or images displayed per second of film or video.
Frame rate is the speed at which those images are shown. Each image represents a frame. To create the perception of motion, the brain automatically adds or fills in the missing information. This speed tricks your brain into thinking the video is playing in one smooth motion.
What is (FPS) Frames per Second?
Frames per Second (FPS) measures how motion video is displayed. With the way our brain adds missing information to create motion, the higher the FPS, the smoother the motion appears before the eyes. For example, if a video is captured and played back at 24 frames per second, that means each second of the video shows 24 distinct still images.
In general, the minimum FPS needed that helps avoid any jerky motion is 30 frames per second. You’ll be looking at around 60 frames per second for high-motion content. But, more on selecting the correct FPS for your videos from among the common FPS values later.
Why Does Frame Rate Matter?
Video making has been simplified dramatically in recent years thanks to innovations in video recording equipment and software related to editing and special effects. That increases the importance of understanding frame rates before you shoot a video, especially when it comes to producing high-quality business content. The frame rate dramatically impacts the style and viewing experience of a video.
When considering the best frame rate for your content, you are choosing between how realistic you want your video to look or whether or not you plan to use different techniques or effects like slow motion or transitions.
What is the Best Frame Rate for Live Streaming Video?
The best frame rate for live streaming should be at least 30fps for live video. While common FPS values are one of the most critical technical aspects of online streaming, they’re not as important as video quality.
The Society of Motion Picture and Television Engineers (SMPTE) standardized frame rates in TV and movies, but frame rates in video content haven’t been. Frame rates are used in digital cameras used on DSLR, mirrorless, and smartphone devices.
These indicate the quality of the camera when capturing video. Cameras have a base frame rate, which you will need to check in your settings before you start capturing content. You can also find frame rate examples in the settings of your video encoder
Video-making is very diverse, so There isn’t just one best frame rate for video per se. Each frame rate example has a specific use. So the best frame rate for your video will depend on your niche, video settings, and overall vibe you want for your content. Here are some use cases for common FPS values used in the video-making industry:
- 24 frames per second is the industry standard for videos on the web, most TV and film,
- 30 frames per second is mostly used for live TV like news programs, concerts, sports, and soap operas. These six extra frames per second make for a much smoother video feel that works great for a less cinematic video.
- 60fps and 120fps are used for recording video to be played back in slow motion
To figure out the best frame rate for your videos, you will have to determine what type of content you’re looking to create. Content should be encoded and uploaded in the same frame rate in which it was recorded when uploading to a hosting platform like Dacast.
Do Higher Frame Rates Mean Better Quality?
Higher frame rates do not necessarily mean better quality. As we mentioned previously, each frame rate example has a specific purpose. The higher frames per second, the slower the slow motion will be.
For example, videos recorded at 120fps can be slowed down to a 24-frame rate, which creates that smooth slow-motion effect. The notion that higher resolution video looks better with higher frame rate examples is dependent on the display capabilities. An OLED display with 60-120 frames per second will show the content much better compared to an LCD at 24-30fps.
Some cameras may be able to film at 120 frames per second; they can only film at 720 pixels instead of 1080. So, the higher the frame rate, the higher the cost of video quality.
Consumers have a low tolerance for bad streams and video quality. For many, 90 seconds is the most they will tolerate when it comes to low-quality content. If, after 90 seconds, the video is still low quality, they will look for a different video.
What’s the Difference Between Common FPS Values: 24fps, 30fps, and 60fps?
The most common FPS values in videos are 24, 30, and 60 fps. Since there are three major frame rates to consider for uploading business video content online, we’re explaining each.
That’ll help ensure your encoder, camera, and other live streaming equipment settings are optimized before you hit “record.”
24fps
This frame rate is the one used by most in Hollywood. It makes video content seem more cinematic. While an average person may be unable to tell the difference between this frame rate and a higher one, most professional video makers can.
One of the main disadvantages of filming in 24fps is that it can look quite choppy and unprofessional if slowed down. If a broadcaster plans to shoot footage to slow it down in post-production, we always recommend filming at a higher frame rate.
30fps
Many modern cameras can film video content in 30 frames per second. Traditionally, this is the best frame rate for live streaming (fps live) for TV video content in the USA. As your camera is capturing more still images per second than it was with 24fps footage, this is ideal for sports and other fast-moving videos.
If you bought your video camera between 2000 and 2010, will likely only have the option to film in 30fps for live streaming fps.
60fps
The 60 frames per second setting is nearly equivalent to 50 frames per second. If the camera you’re planning to create video content on was manufactured in the US, it would likely offer the ability to film at 60 fps rather than 50. Some cameras will have the option to film in both.
This live video FPS is a high frame rate mainly used for slo-mo. Typically a video is recorded at 60fps and is then slowed down to 24 or 30 fps post-production. That allows for a smooth slow-motion effort during post-production.
Any frame rate over 60 frames per second is considered a high-speed frame rate. Some cameras on the more professional side will go as fast as 1,000 frames per second. You may have seen video examples like a bullet going in slow motion or a water balloon popping.
Which is Better: 24fps, 30fps, or 60fps?
After learning the differences between the most common FPS values, you may be wondering which is the best frame rate for live fps streaming: 24fps, 30fps, or 60fps?
All three common frames per second rates have a place in today’s digital world. There isn’t one answer to which is better, 24fps or 60fps, or better, between 30fps or 60fps. Your frame rate choice depends on your video camera, your encoder settings, post-production, the type of content you’re creating, and where you will be hosting it. Shooting at either 24 or 30fps should give you your camera’s best performance and quality it has to offer.
How to Choose the Best Common FPS Values and Frame Rate for Streaming Video
Since you will choose your live FPS rate based on what you’re shooting, here are the best use cases per streaming frame rate:
24fps
- If someone is speaking
- Landscapes
- Video where you need to get details and textures
- HD video
- Reviews
- Podcasts
- Most live-streams
30fps
- Can be used as-is and can be slowed down to 24fps
- Sports and other fast-moving content
- TV shows and vlogs
- HD video
- Cinematic shots
- Action shots
- Shots that require you to capture extra details
50fps
- This is the interlaced field rate of PAL. Some 1080i HD camera record at this frame rate
- HD video
- High-speed games
- Gaming reviews and playbacks
59.94fps
- HD cameras can record at this frame rate. While it’s sometimes referred to as 60fps, it’s best to use 59.94 unless you mean 60fps
- Compatible with NTSC video
60fps
- When the subject needs a more graceful appearance
- Adds emotions to the shot
- Great to slow down video shots during sporting events
- Can be slowed down to the perfect slow-motion ability
- HD video
- Fast-paced content
- Action content
When you know the type of content that you’ll be shooting, ensure that your camera setting is correct and so is your video encoder. Once those are dialed into the correct streaming frame rate, you have chosen the best frame rate for your video.
If all this still seems confusing to you, try using a lower FPS value to ensure your live-stream plays without lag for your viewers. Unless a specific requirement calls for a higher FPS, steer clear of it. For newbie broadcasters, a simple rule of thumb to keep in mind is:
You can get away with lower FPS (which would also lower the amount of bandwidth you are using) if you are streaming slow-motion content. You will probably want a higher FPS to make the motion feel more fluid if there is heavy motion.
Frame Rates and Live Streaming FPS
When it comes to video frame rates for live video (FPS live) there are many factors to consider. Suppose you’re a business interested in live streaming video content to your employees or your clientele. In that case, you will have to know the settings that create the best-finished video product.
Most online streaming platforms will back 60fps. At a minimum, you should try stream video content at least 30fps.
As with video resolution, frame rates affect video bandwidth requirements. Video content with a higher frame rate has more data to transmit than content with a lower frame rate.
Other reasons why FPS live streaming frame rates matter in video streaming include
- When the live stream concerns something fast-paced like a sports event stream or a concert, a stream with higher frames per second will produce better video. The event’s fast-moving motion can be captured using more frames per second.
- For live streams where the event isn’t high-paced, like educational content, tutorials, a church service, or a government meeting, high frame rates aren’t typically required as most of the motion can be adequately captured by a lower fps as well.
Higher frame rates are becoming the new norm as increased video bandwidth capability reaches more viewing devices. That means until it’s the norm, it’s critical to pay attention to all the settings on your devices and encoders to ensure the proper live FPS rates are being chosen.
Streaming Frame Rates and Encoders
According to HubSpot, online video was the number one media format in 2020. While video technology continues to advance, the quality of the captured images has never been better. But, the file sizes have also grown exponentially. That brings the various types of live video encoders to light.
Encoders are either hardware or software that brings raw video and converts it into a digital format and size that becomes compatible with online players and devices. There are two types of encoders – software encoders and hardware encoders. Let’s discuss the differences.
Software encoders
- Video conversion programs that run on a computer
- Have a graphic interface to manage the conversion process
- Allow control over elements such as video bitrate and stream quality
- Low cost and easy operation
Hardware encoders
- Standalone, dedicated devices that do not require a computer to use
- The only purpose is to encode raw video into streaming data
- Small, portable case but can also be set up as large, permanent fixtures
- Include specialized internal components that don’t share resources with any other processes
To upload your content, your must encode your video to fit the needs of your video hosting platform.
Recommended Live Encoder Settings
At Dacast, we use the real-time messaging protocol for RTMP ingest of live streams. The platform transcodes that live video content into the HLS streaming protocol. Finally, that streaming content reaches your viewers via top-tier CDNs.
Most live stream frames move from the encoder to the online video platform in RTMP format. Then the platform transcodes this video into HLS. RTMP encoders are all configured in the same basic manner. To ensure your live stream is stable and fully functional, if you’re planning to live stream the video content you’re creating, you will have to configure your encoder to use the settings below.
First, ensure you are following everything in the Common Settings section. Then select the most appropriate bitrate & resolution (depending on your needs) and configure all settings for that size exactly.
Common Settings:
The following settings are recommended for optimal live streaming FPS, regardless of your selected resolution and bitrate:
VIDEO CODEC | H.264 (X.264 may work) |
FRAME RATE | 25 or 30 |
KEYFRAME INTERVAL | 2 secs (or 2x frame rate) |
SCANNING | Progressive |
ENCODING BITRATE | Constant (CBR) |
AUDIO CODEC | AAC |
AUDIO BITRATE | 128 kbps |
AUDIO CHANNELS | 2 (Stereo) |
AUDIO SAMPLE RATE | 48 kHz (48,000 Hz) |
Resolution & Bitrate Settings:
Select one of the following configurations and ensure your encoder is set up with these exact settings for optimal live streaming:
ULD | LD | SD | HD | FHD | |
Name | Ultra-Low Definition | Low Definition | Standard Definition | High Definition | Full High Definition |
Video Bitrate (kbps) | 350 | 350 – 800 | 800 – 1200 | 1200 – 1900 | 1900 – 4500 |
Resolution Width (px) | 426 | 640 | 854 | 1280 | 1920 |
Resolution Height (px) | 240 | 360 | 480 | 720 | 1080 |
H.264 Profile | Main | Main | High | High | High |
Video and audio codec:
- The video codec profile we recommend using for H.264 is High. You may also see an X.264 option; this is simply another implementation of the same protocol. You can use either one.
Audio bitrates:
ULD | LD | SD | HD | FHD | |
Name | Ultra-Low Definition | Low Definition | Standard Definition | High Definition | Full High Definition |
Video Bitrate (kbps) | 350 | 350 – 800 | 800 – 1200 | 1200 – 1900 | 1900 – 4500 |
Audio Bitrate (kbps) | 64 | 64 | 128 | 256 | 256 |
Bitrate Recommendation:
- We recommend a standard or low definition (480p/360p) under 1000kpbs (audio and video bit-rates included based on the table above).
Frames per second (FPS):
- Simply put, most users should generally set frames per second (fps) at 30. For people in certain regions of the world, however, 25 frames per second are standard. However, 30 fps will work anywhere.

Plus and Minus
Advantages of High Frame Rates (e.g., 60fps):
- Smooth Motion: High frame rates result in exceptionally smooth motion, making them ideal for fast-paced action scenes or sports broadcasts.
- Enhanced Realism: Higher frame rates can create a more lifelike and realistic viewing experience, reducing motion blur and flickering.
- Slow Motion: Footage shot at high frame rates can be easily slowed down during post-production to achieve a smooth slow-motion effect, adding cinematic value.
- Reduced Judder: High frame rates reduce juddering or stuttering, providing a seamless and immersive viewing experience.
- Ideal for Gaming: High frame rates are essential in gaming to ensure responsive and fluid gameplay, reducing input lag.
Disadvantages of High Frame Rates (e.g., 60fps):
- File Size: High frame rate videos typically have larger file sizes due to the increased amount of data per second, requiring more storage space.
- Compatibility: Not all devices and platforms support high frame rates, potentially limiting your audience’s access to your content.
- Unnatural Look: Some viewers find videos shot at very high frame rates (e.g., 120fps or above) to have an unnatural, almost hyper-realistic appearance, which may not be suitable for all content.
Advantages of Lower Frame Rates (e.g., 24fps):
- Cinematic Aesthetics: Lower frame rates, such as 24fps, have been a standard in filmmaking for decades, giving content a traditional cinematic look.
- Reduced Storage: Lower frame rates result in smaller file sizes, making them easier to manage and store.
- Ideal for Narrative Content: 24fps is well-suited for storytelling and narrative content, providing a more artistic and deliberate pacing.
Disadvantages of Lower Frame Rates (e.g., 24fps):
- Motion Blur: Lower frame rates may exhibit more noticeable motion blur in fast-action scenes, potentially reducing video quality.
- Incompatibility with High Motion: They might not be suitable for content with rapid motion, such as sports, as it can result in choppy or less fluid visuals.
- Not Ideal for Gaming: Lower frame rates in gaming can lead to input lag and a less responsive gaming experience.
In summary, the choice between high and low frame rates depends on your specific content and goals. High frame rates offer smoother motion and enhanced realism but can result in larger file sizes and may not be universally supported. Lower frame rates provide a cinematic look and smaller file sizes, making them suitable for narrative content but less ideal for fast-action scenes. The decision should align with your content’s intended style and the preferences of your target audience.
