what is the transcoding

Hello steemit family,

PART#1

We will describe the elements of digital media file types that we use for different purposes in daily life, how the previously written code conversion works on these elements, what problems may arise when moving from one form to another, and which workflows are most effective for code conversion under different conditions. ), it turns out that the digital image does not have the data capacity necessary to accurately describe a set of pictures of most recording, storage and playback conditions. then the development of compression / decompression algorithms (codecs) that will require less data bandwidth with the progress of tenological systems began. I wrote the most common media protocols below.
Examples of commonly used carrier file types in the world:

QuickTime MOV: A cross-platform multimedia format specifically developed for Apple.
MPEG-2 Transport Stream and Program Stream: A type of file developed by the Motion Pictures Expert Group, used in optical media (DVD Video, Blu-ray Disc) and digital broadcasting (ATSC).
WMV and MP4: used for internet distribution
GFX (General eXchange Format): Developed by Grass Valley and standardized by SMPTE.
LXF: A broadcast server format developed by Harris (today Imagine Communications).
MXF (Material eXcHanGe Format): Standardized by SMPTE.
