It allows the user to specify a specific target file size. In the first pass, the encoder analyzes the input file and automatically calculates possible bitrate range and/or average bitrate. In the last pass, the encoder distributes the available bits among the entire video to achieve uniform quality. [10]
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:
[2] [4] The software also offers various effects like video rotation, captions, watermarks, and text overlay. [9] [10] It also includes a built-in preview feature, that enables users to view their videos before and after the conversion process. [10] It supports batch conversion and running conversion in background. [11] [12]
Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general-purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay.
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]].
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]
File size is a measure of how much data a computer file contains or how much storage space it is allocated. Typically, file size is expressed in units based on byte. A large value is often expressed with a metric prefix (as in megabyte and gigabyte) or a binary prefix (as in mebibyte and gibibyte). [1]
High 4:2:2 Profile (Hi422P): Primarily targeting professional applications that use interlaced video, this profile builds on top of the High 10 Profile, adding support for the 4:2:2 chroma sampling format while using up to 10 bits per sample of decoded picture precision.
