Gpu Vs Cpu Encoding (Expert Answers)

Encoding is the process of converting video files from one format to another. It’s essential for making sure that the video can be played on various devices and platforms. When a video is encoded, it’s compressed and the file size is reduced, which makes it easier to store, transmit and share. The process of encoding involves a variety of tasks, such as transcoding, transrating, and transsizing.

Transcoding is the process of converting a video from one format to another. For example, converting a .mov file to a .mp4 file. Transcoding is important because not all devices support all video formats, and it ensures that the video can be played on a wide range of devices and platforms.

Transrating is the process of changing the bitrate of a video. Bitrate is the amount of data that is used to represent a second of video. A higher bitrate results in a higher-quality video, but also results in a larger file size. Transrating is important because it allows you to adjust the quality of the video to match the specific needs of the end user.

Transsizing is the process of changing the resolution of a video. Resolution is the number of pixels in a video. A higher resolution results in a higher-quality video, but also results in a larger file size. Transsizing is important because it allows you to adjust the video to match the resolution of the device that it will be played on.
