What is an H261 file?
An H261 file is a video saved using the H.261 video compression standard. It likely contains footage recorded during a video conference. H261 files are quite rare, so most popular media players cannot play them.
The H.261 video compression standard was created and is maintained by the International Telegraph Union (ITU), a division of the United Nations that coordinates the world's response to information and communication technology issues. The standard was created in 1988 and last updated in 1993, and it was the first video compression standard to use discrete cosine transform (DCT) compression. H261 files are the precursors to .H262, .H263, .H264, and .H265 files, which utilize updated iterations of the H.261 compression standard.
How do I open an H261 file?
Because H261 files are so uncommon, most popular media players cannot play them. However, you can play H261 files in VLC media player, and you can convert them to a more usable video format using FFmpeg.
