This concept ties directly to how we naturally see the world. The frame rate of a video greatly impacts the look and feel of a video, which in turn determines how realistic the video appears. Controversy aside, here are four things you need to keep in mind when choosing a frame rate. As stated above, different frame rates yield different results, so selecting the best one means going with the option that best fits what you’re trying to create.Įven though frame rate is a relatively straightforward concept, there’s a fair amount of controversy around which rates provide the best viewing experience, and there’s research that builds the case for just about any frame rate. How do I choose the best frame rate for my video?įirst of all, there is no such thing as the “best” frame rate. On the other hand, people who create animated GIFs will often sacrifice detail for a smaller file size and choose a low frame rate. A higher frame rate keeps the motion smooth and the details crisp. Live videos or videos with a lot of motion, such as sporting events or video game recording, often have higher frame rates because there’s a lot happening at once. Different frame rates yield different viewing experiences, and choosing a frame rate often means thinking about multiple factors, such as how realistic you want your video to look or whether or not you plan to use techniques like slow motion or motion-blur effects.įor example, Hollywood-style movies are usually displayed at 24fps, since this frame rate is similar to how we see the world and creates a very cinematic look. Why does frame rate matter?įrame rate greatly impacts the style and viewing experience of a video. The speed at which they’re shown tricks your brain into perceiving smooth motion. So if a video is captured and played back at 24fps, that means each second of video shows 24 distinct still images. It’s usually expressed as “frames per second,” or FPS. Each of those images is called a “frame.”įrame rate, then, is the speed at which those images are shown, or how fast you “flip” through the book.
#FRAMES PERSECOND APP SERIES#
Whether digital or old-school film, video is a series of still images that, when viewed in order at a certain speed, give the appearance of motion. Remember those cool little flipbooks where a pad of paper had an image on every page, and when you flipped through the pages quickly, the image would appear to animate and move?
That clears things right up!Īt any rate the method allows for images - well, technically spatiotemporal datacubes - to be captured just 100 femtoseconds apart. Combined with the image acquired by the femtosecond streak camera, we can use what is called a Radon transformation to obtain high-quality images while recording ten trillion frames per second,” explained co-author of the study Lihong Wang. So to improve this, we added another camera that acquires a static image. “We knew that by using only a femtosecond streak camera, the image quality would be limited. It combines a streak camera with a second static camera and a data collection method used in tomography.
