• UtVideo is a series of codecs (video encoders) designed and maintained by UMEZAWA Takeshi (Japan).
• Thanks to these codecs, the generated videos are 10 times smaller than a raw AVI file, while fully retaining lossless quality.
• The version used is completely free and ad-free.
• This software is open-source and has been updated for over 18 years. It is primarily used for scientific devices (such as microscopes and telescopes), making it highly reliable.
