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 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.

A .gifv "file" is simply a HTML webpage which includes a HTML video tag, where the video has no sound. As there were large communities online which create art using the medium of short soundless videos in GIF format, GIFV was created as a functionally similar replacement with vastly smaller filesizes than the inefficient GIF format.
In contrast, lossy compression (e.g. JPEG for images, or MP3 and Opus for audio) can achieve much higher compression ratios at the cost of a decrease in quality, such as Bluetooth audio streaming, as visual or audio compression artifacts from loss of important information are introduced.
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.
A video coding format [a] (or sometimes video compression format) is a content representation format of digital video content, such as in a data file or bitstream.It typically uses a standardized video compression algorithm, most commonly based on discrete cosine transform (DCT) coding and motion compensation.
This freeware also performs functions such as downloading videos from online video-sharing sites such as YouTube, Facebook, Vimeo, Niconico, MetaCafe, etc. [9] Users can edit videos as they like, such as cutting, rotating, flipping, adding video effects, or combining multiple videos into one file.
