The disadvantages of transcoding are that there is quality loss when transcoding between lossy compression formats, and that the process is highly CPU-intensive. This article compares video converters that have their own articles on Wikipedia.
The software converts most video files into other formats such as AVI, MKV, MOV, Ogg, VOB, MP4, FLV, WMV, MP3, etc. [5] [6] [7] [8]. This freeware also performs ...

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.
Video can be compressed immensely (e.g., 100:1) with little visible quality loss Audio can often be compressed at 10:1 with almost imperceptible loss of quality Still images are often lossily compressed at 10:1, as with audio, but the quality loss is more noticeable, especially on closer inspection.
LosslessCut is a free, platform independent video editing software, which supports numerous audio, video and container formats. [4] [5]It is a graphical user interface, with MacOS, [6] Windows [7] and Linux [8] support, using the FFmpeg multimedia framework.
ALAC data is frequently stored within an MP4 container with the filename extension.m4a. This extension is also used by Apple for lossy AAC audio data in an MP4 container (same container, different audio encoding). The codec can also be used by the .CAF file type container, though this is much less common.
