IPB is more compressed and creates a lower-quality image and a smaller file size. While your specific camera is going to influence to what degree that compression is, the short of it is this: All-I compression is less compressed and creates a higher quality image (and a larger file size). These settings are all about compression. Objective: In this study, we sought to compare the radiation dose between peripheral vascular interventions using fluoroscopy frame rate of 7.5 frames per. Measured in hertz (hz), this measures how quickly a screen refreshes or “recycles” an image and usually correlates to the maximum rate that can be displayed on a particular screen. What’s the difference between Frames Per Second and Refresh Rate?Ī refresh rate is typically given to a display rather than a camera/filming system. This, since it is slower than the human eye, is what results in this frame rate being more cinematic overall, while 30fps is smoother and feels slightly more true-to-life. But in time, film was too expensive to maintain that frame rate and it kept getting reduced until it finally arrived at an industry standard of 24fps. Different scientists over the years have debated optimum frame rates-with Thomas Edison recommending 46fps. The minimum frame rate for the human mind to perceive motion is 16fps. Great Question-honestly, it’s purely arbitrary and is rooted in film history and economics. So How did we land on 24fps (or 30fps) as a standard? (Rest Assured, Instagram doesn’t conform your 24fps content to 30fps on upload it retains it’s original frame rate) Additionally, a lot of apps (like Instagram ) use 30fps as their standard for filming, so it’s becoming even more prevalent in daily films that you’ll see in your feed. If you’re filming live events and want a smooth, seamless look, then 30fps might be more of what you’re after. If you want to add drama and depth to it, you can include 60fps or 120fps and play it back in 24fps (either 2.5x or 5x slower than it was filmed). If you need something more cinematic, then 24fps is great. Well, it all depends on what you’re after! Each frame rate has a specific use, so it might be helpful to first ask yourself what you want to film and create.
