AviUtl portable is a video editor with video filtering features. You can install various plugins and scripts to improve its features. It has a simple interface that makes video editing quite intuitive. You can edit multi-channel audio/video tracks in its timeline.
AviUtl can edit (split, merge, change speed or interlace, etc.) or apply filters (sharpening, change colours, add black strips, etc.) to a AVI format video. You can add 3rd-party plug-ins to add multiple functions, removing ghosts, handling other formats like mp4 or divx, and more. The Advanced Editing Plug-in changes AviUtl like a different software; which enables you to make/edit videos even from zero.
