AviSynth is a powerful script-based video editing tool, widely recognized for its versatility and effectiveness in post-production. Ideal for both editing and converting videos, AviSynth integrates seamlessly with any application supporting AVI files. It functions as a frame server, efficiently passing individual frames to other programs. The software boasts a comprehensive library of features, including resizing, cropping, adding borders, and decoding, making it an indispensable tool for video editors. Whether you're a professional or a hobbyist, AviSynth offers the robust capabilities needed to enhance your video projects.


AviSynth definitely has its perks, like great output quality, but I struggled with the scripting side of things. Some of the features I wanted were buried in menus. I had some success, but overall, it's a mix of love and frustration.
