Convert AVI to 265
About AVI
AVI (Audio Video Interleave) is one of the oldest video formats, developed by Microsoft in 1992. As a container format, it can use a wide variety of codecs for video and audio. While it was once extremely popular, it has been largely superseded by more modern formats like MP4. It lacks modern features like native support for streaming or subtitles and can result in very large file sizes.
About 265
This is a raw video stream encoded with the H.265/HEVC codec, using the '.265' file extension. It is functionally identical to a '.hevc' file. It contains the highly compressed video data without any audio or container information. It is used in professional workflows before the final video file is assembled.

Frequently Asked Questions
Is AVI still a useful format?
For new video projects, AVI is not recommended. Its main use today is for compatibility with older systems or legacy content. Modern formats like MP4 offer better compression, more features, and wider compatibility.
Why do some AVI files not play audio?
This is a common issue with AVI files and is due to its reliance on codecs. The AVI file itself is just a container. If your system does not have the specific audio or video codec installed that was used to create the file, it will not be able to play correctly.
Why do some files use .265 instead of .hevc?
It is simply an alternative file extension for the same type of raw H.265 video stream. There is no technical difference.
Is a .265 file smaller than a .264 file?
Yes, for the same source video at the same visual quality, the .265 file will be significantly smaller (often about half the size) than the .264 file, thanks to the superior compression efficiency of the H.265/HEVC codec.
