Not to worry! 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? This is how video works. 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.
So if a video is captured and played back at 24fps, that means each second of video shows 24 distinct still images.
Frame rate greatly impacts the style and viewing experience of a video. 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. For 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.
A higher frame rate keeps the motion smooth and the details crisp. On the other hand, people who create animated GIFs will often sacrifice detail for a smaller file size and choose a low frame rate. Controversy aside, here are four things you need to keep in mind when choosing a frame rate.
The frame rate of a video greatly impacts the look and feel of a video, which in turn determines how realistic the video appears. That some day, very soon, the illusions we used to watch on screens, flickering in the darkness, will run into our living room and tell us that we have an email.
In traditional cinema, directors use shot selection , camera movement and editing to determine the pace and focus of each scene. But all those tools all go out the window to varying degrees when working with VR, which requires minimal cutting and camera movement so as not to disorient your viewer or make them barf. This can be done a variety of ways: blocking and motion, set layout, lighting, audio, etc. Just remember: since everything in your video will likely need to play out in longer unbroken takes without you on set, pre-production and rehearsal are your best friends.
Leave nothing to chance. Again, consider your project and what it requires. Being precise about your production workflow is critical in VR, as errors made at the top of the chain can cascade down and complicate production in a variety of frustrating ways. After pre-production comes the actual shoot. Luckily, recent versions of Adobe Premiere are fully equipped for degree video as long as you create your new project file as such. Edit, export and test your cut in an actual VR headset.
Repeat the process until satisfied. Spatialized audio tracks can be created via third-party programs such as this workstation available from Facebook and converted into a standard stereo audio file that can be edited in Premiere.

Or for that matter, why not 10 or ? The short answer: Not much, the film speed standard was a hack. You are not a camera. Ever noticed that, back in the silent film era, films looked jerky and unnatural? Because the cameras were hand cranked, the rate of each frame could vary from 14 to 26fps, yet were projected at 24fps no matter what. This variable was eliminated when the Vitaphone process came to town, synchronising sound-to-picture and giving birth to the 'talkies', starting with the The Jazz Singer in which also had the distinction of being the first filmed musical.
The standard frame rate was set to 24fps to make the whole process work. Even though lower budget silent films were still being produced after and newer and better sound recording methods were developed including the addition of recording sound next to the picture along the film strip , filming at 24fps became the standard. It also made economic sense as well.
Film stock wasn't cheap and it was decided that a rate of 24 was the best compromise between how much stock would be needed and creating a satisfactory level of realistic motion. Fast forward a few decades to the invention of the television and broadcast standards, including interlaced and the progressives, and different frame rates came into play.
Meanwhile, cinema stayed faithful to the 24fps standard and audiences grew accustomed to it. Even today, if you want to achieve a 'cinematic look' to your home movies, you would use this standard. There have been attempts in the past to move on, to evoke a similar passion for another standard or look, but so far things have been fruitless. I remember back in looking forward to Michael Mann's true story gangster movie Public Enemies. The motion seemed so lifelike, some of it was shot with the latest high definition cameras, and it looked set to blow my amateur movie-going mind.
What we got was something different. Not just digital noise in the darker scenes, but the whole affair just looked wrong somehow. The smooth motion of the actors looked like they had come from segments of a behind the scenes documentary, filmed on someone's smaller camcorder.
Although it was a mixture of film and digital, the setups used e. These settings are all about compression. 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. IPB is more compressed and creates a lower-quality image and a smaller file size. What is Frame Rate, and why does it matter? Learning Frame Rate.
