We recommend 16:9 players be at least 480 pixels wide and 270 pixels tall.Īny web page that uses the IFrame API must also implement the following JavaScript function: If the player displays controls, it must be large enough to fully display the controls without shrinking the viewport below the minimum size. Most modern browsers support postMessage.Įmbedded players must have a viewport that is at least 200px by 200px. The user's browser must support the HTML5 postMessage feature. It also details the different JavaScript functions that you can call to control the video player as well as the player parameters you can use to further customize the player.

It identifies the different types of events that the API can send and explains how to write event listeners to respond to those events. This guide explains how to use the IFrame API. You can also add event listeners that will execute in response to certain player events, such as a player state change. Using the API's JavaScript functions, you can queue videos for playback play, pause, or stop those videos adjust the player volume or retrieve information about the video being played. There’s a lot more technical detail to how frame rates work, but with this knowledge, you can at least identify them and choose which one is right for your current project.The IFrame player API lets you embed a YouTube video player on your website and control the player using JavaScript. If you’re vlogging or shooting fast-paced action, you’d want to run with a high frame rate to negate the blur from slower frame rates. If you’re filming travel vlogs and want to capture a cinematic atmosphere, you might want to run with 24fps or 25fps. Ultimately, this will come down to the type of content you’re creating. Common frame rates include: 24, 25, 30, 48, 50, and 60 frames per second (other frame rates are also acceptable). In its guidelines, YouTube states:Ĭontent should be encoded and uploaded using the same frame rate that was used during recording. If this is the case, what’s the best frame rate to use? Well, due to the flexibility of online platforms, there isn’t one.
Online content, such as YouTube and Facebook videos, doesn’t need to adhere to practices of television standards, and likewise, they also don’t need to conform to cinematic frame rates. While this should be kept in mind when working with any video content, it’s crucial in broadcast video. There are also Drop-Frame variations of 24fps and 60fps.
To compensate for this frame rate offset, a Drop-Frame’s timecode must skip frames 00 and 01 once a minute, except multiples of ten minutes. This format is known as Drop-Frame, whereas 30fps would be called Non-Drop-Frame. Broadcasting in the 29.97 format has since become industry standard. Fortunately, slowing the frame rate to 29.97 eliminated this static. When color television was first introduced, the added signal that provided hue and saturation levels - known as the Color Subcarrier - caused interference with existing black-and-white televisions in the form of visible static. Slowing down the frame rate decreased the amount of visible static. In my article “ The Surprisingly Fascinating World of Frame Rates,” I delve more in-depth into the reasoning from the switch from 16fps to 24fps. While there’s no one specific reason as to why we start at 24fps, we can conclude the primary reasons are math and the introduction of recording sound. In the early 1900s, there was no standard frame rate, but it was in the interest of studios to keep the frame rates low since higher frame rates require the use of more film. However, as soon as more images pass within that second, the gap between each image shortens, and our brains recognize the images as motion. Unlike shutter speed, where there seems to be an abundance of speeds to choose from, with frames per second, the settings usually adhere to a set of standards, and often, you’ll be able to choose from the small selection of: 23.976, 24, 25, 29.97, 30, 48, 50, 59.94, and 60.īut, why do they start at 24fps? Why not 19 or 20? Well, humans can typically recognize ten to twelve passing frames as identifiable individual images. In the early days of film, frame rates were kept low to cut down on cost.
