What You'll Learn
High frame rates for action shots
When it comes to capturing action shots, a higher frame rate can be beneficial for several reasons. Firstly, a higher frame rate allows you to capture more individual frames in a second of video. This is especially useful for fast-paced action scenes where you want to capture as much detail as possible.
Secondly, a higher frame rate can help create smoother footage. This is because a higher number of frames means that each frame captures a smaller amount of movement, resulting in a smoother transition from one frame to the next. This can be particularly advantageous for action shots that involve quick movements or camera panning.
Additionally, a higher frame rate can be useful if you plan to slow down your footage for replays or reviews. When you slow down high-frame-rate footage, you can still maintain clear and detailed images. This is often used in sports broadcasting to capture fast-moving subjects and then review the action in slow motion.
While higher frame rates offer these benefits, it's important to consider the limitations of the human eye. The human eye can only appreciate between 30 and 60 frames per second. Going beyond this range may result in diminishing returns, and very high frame rates can make footage look unnatural, especially if there is minimal movement.
It's also worth noting that higher frame rates result in larger file sizes since more frames are being captured. This can be a consideration when choosing your frame rate, as it will impact storage requirements and the speed of uploading or streaming your footage.
Finally, when it comes to audio, there have been issues with GoPro audio at higher frame rates, particularly at 120fps. Disabling the wind noise reduction feature and using foam encasing can help improve audio consistency, even in windy conditions.

Lower frame rates for standard shots
When it comes to filming standard shots with your GoPro, it's essential to choose the right frame rate to achieve the desired look and feel for your footage. Here are some insights to guide you in using lower frame rates for standard shots:
24fps for Cinematic Look
The standard frame rate for movies is 24fps as it creates a cinematic feeling. This frame rate is widely used in films and TV shows, especially for scenes with minimal movement, such as dialogues, landscapes, or quiet streets. Shooting at 24fps with your GoPro can give your footage a cinematic look and feel, making it a great choice for narrative-driven or aesthetically focused videos.
30fps for Standard Video and Streaming
The 30fps frame rate is the most commonly used in standard video shooting and is considered ideal for online streaming and uploading. Live broadcasts like news and sports are typically filmed at 30fps. This frame rate is suitable for various applications, including marketing videos, product promotions, and standard video recordings.
Lower Frame Rates for Specific Effects
Lower frame rates, such as 6 to 8fps, can be used in combination with step printing (duplicating frames) to achieve unique effects. For instance, playing back footage at 6 to 8fps at a regular speed of 24fps creates a jerky, real-time action with significant motion blur. This technique is often used in cinema to achieve specific artistic visions.
Lower Frame Rates for Practical Considerations
Lower frame rates like 24fps or 30fps are also practical choices when considering the limitations of playback devices. Older TVs and computer monitors may not support high frame rates, so sticking to lower frame rates ensures compatibility with a broader range of devices.
In conclusion, when using your GoPro for standard shots, consider the narrative, aesthetic, and practical implications of your frame rate choice. Lower frame rates like 24fps and 30fps offer versatility, compatibility, and a cinematic look and feel for your footage.

Frame rate and audio sync issues
GoPro cameras offer a range of frame rate options, from 24 FPS to 240 FPS, depending on the model. A higher frame rate is generally used for capturing fast-paced or high-movement activities, such as sports or slow-motion shots, while a lower frame rate is used for standard shots or scenes with minimal movement.
Audio issues can also arise when the "Auto Low Light" setting is turned on, which can be fixed by turning it off in bright conditions. Additionally, GoPro's wind noise reduction feature can interfere with the microphone's output during high-speed sections, resulting in inconsistent audio. This can be resolved by disabling wind noise reduction and using external accessories, such as foam encasing, or a "dead cat" fur cover, to reduce wind noise.
It is worth noting that lower frame rates can improve lighting conditions, as they allow for longer shutter speeds. This can be beneficial in low-light environments, such as underwater or indoor scenes. However, it is generally recommended to keep the shutter speed at least double the FPS rate.
When dealing with audio sync issues, it is important to consider the software used for playback or editing. Certain media players or video editors may handle frame rates differently, affecting the sync between the video and audio tracks.
In summary, while the frame rate does not directly affect the sound in GoPro footage, it is crucial to consider the relationship between frame rate, lighting, and audio settings to ensure optimal video and audio quality.

Frame rate and wind noise reduction
When shooting outdoors, wind noise can be a frustrating issue that interferes with audio recordings. Wind noise occurs when moving air rushes directly into the microphone, creating unwanted distortion that can drown out voices and other important sounds, affecting the overall quality of the recording.
To address this issue, wind noise reduction techniques are essential for achieving professional-sounding results. One approach is to utilise dedicated tools that can lessen wind noise efficiently. For instance, the AnyRec Video Converter offers a Noise Remover tool that allows users to clean and enhance audio by removing wind noise, adjusting volume, and replacing sound. Additionally, Audacity, a free audio editor, provides powerful noise reduction features, including equalisation and high-pass filtering, making it ideal for wind noise removal.
Another strategy to mitigate wind noise is to use foam encasing or "dead cat" fur stick-ons for the microphone. While these accessories may alter the appearance of the GoPro, they effectively reduce wind rumble without the constant hassle of replacing parts.
Furthermore, the choice of frame rate can also impact wind noise reduction. Higher frame rates, such as 120fps, have been associated with audio issues, particularly during high-speed sections. In such cases, disabling the wind noise reduction feature and opting for lower frame rates like 24fps or 30fps can result in more consistent audio, even in windy conditions.
Additionally, video editing software like Winxvideo AI, Premiere Pro, and DaVinci Resolve offer tools to enhance audio quality and remove wind noise. These applications provide various options, including AI noise suppression models, noise attenuation limit adjustments, and volume control, ensuring that wind noise is minimised without compromising the natural sound of the recording.

Frame rate and video quality
Frame rate, or frames per second (FPS), is the frequency at which consecutive images (frames) are displayed in a video. The human eye can analyse 10-12 images per second and perceive them as motion; the higher the frame rate, the smoother the motion appears.
The frame rate chosen will depend on the type of video being shot. 24fps is the standard used in Hollywood movies as it creates a cinematic feeling with a certain amount of motion blur. This rate is similar to how we see the world and gives video a dreamlike quality. 24fps is also suitable for scenes without many moving details, such as dialogues or landscapes.
For videos with a lot of movement, such as sports or video game recordings, a higher frame rate is often used to keep the motion smooth and the details crisp. 30fps is the most widely used frame rate and is considered the best for online streaming. 60fps has long been considered the minimum for smoothly animated video games.
The choice of frame rate will also depend on practical considerations, such as file size and export times. Higher frame rates result in larger file sizes as more frames are captured, and this can impact the time it takes to export and upload videos.
GoPro allows users to record a video at 24 FPS to 240 FPS depending on the model. Lower frame rates such as 24fps or 30fps will provide a higher bitrate, which equals better video quality.
