Apple ProRes is a high quality, "visually lossless" lossy video compression format developed by Apple Inc. for use in post-production that supports video resolution up to 8K.It is the successor of the Apple Intermediate Codec and was introduced in 2007 with Final Cut Studio 2. [1]
Video is encoded with the AVC/H.264 compression scheme. Audio is encoded with the AAC codec. The compressed audio and video are multiplexed into a QuickTime file. To reduce data rate and hardware requirements, video frame has size of 960 horizontal by 540 vertical pixels with pixel aspect ratio of 1:1, which results in 16:9 display aspect ratio.
A video file format is a type of file format for storing digital video data on a computer system. Video is almost always stored using lossy compression to reduce the file size. A video file normally consists of a container (e.g. in the Matroska format) containing visual (video without audio) data in a video coding format (e.g. VP9 ) alongside ...
There are two types of links to a video: File – To create a link to the video's File Description Page, use [[:File:Time Lapse of New York City.ogv]]. To make the text of a link to the video's File Description Page appear as some text other than the video's filename, use [[:File:Time Lapse of New York City.ogv|some text you prefer]].
Thus, a representation that compresses the storage size of a file from 10 MB to 2 MB yields a space saving of 1 - 2/10 = 0.8, often notated as a percentage, 80%. For signals of indefinite size, such as streaming audio and video, the compression ratio is defined in terms of uncompressed and compressed data rates instead of data sizes:
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
Transitions - help video clips smoothly go into one another, dissolve or overlap two video or image files. [13] Fade in and fade out video and audio files - dissolve a video to and from a blank image, reduce the audio volume at the end of the video and increase at the beginning. Slideshow creation - create a presentation of a series of still ...
Files is a file management app developed by Apple Inc. for devices that run iOS 11 and later or iPadOS. [2] Discovered as a placeholder title in the App Store just prior to the company's 2017 Worldwide Developers Conference , the app was officially announced at the conference shortly thereafter.
