From Avisynth wiki
This page should become an overview about AviSynth related utilities.
- AvsPmod - Highly recommended; closest thing to an GUI/IDE. AvsPmod is a continued develpoment of AvsP. Latest build can be found here.
- AVFS - a virtual file system that exposes the output of AviSynth scripts through the file system as a set of virtual media files. This allows AviSynth to feed media applications and converters that do not use the VFW API. It also allows accessing AviSynth script output through network shares, and allows mixed use of 32 bit and 64 bit video processing and consuming applications. AVFS mounts *.avs files as *.avi & *.wav files.
- AVS2AVI - A command line program that compresses video from an AviSynth script using any VFW codec. See archived homepage | usage examples
- avs2pipemod - a CLI tool to pipe raw/y4m video and wav/extwav/raw audio to various audio/video encoders. It has other useful functions like benchmarking, saving pixel values to a text file, it can suggest x264 settings for Blu-ray disc encoding, and also has support for high bit depth video. avs2pipemod is the continued development of avs2pipe. GitHub repository
- REWAVI - Rewritten/modified WAVI; only the source code is available at the moment.
- WAVI - Extracts WAV audio from AVI/AVS files. The primary purpose of this tool is to save audio tracks from AviSynth. See original SourceForge homepage
- Avs2YUV - Piping tool commonly used to pipe y4m and raw video (including high bit depth) to encoders like x264, x265, and FFmpeg/Libav (among others).
- avs4x26x - AviSynth to x265,x264, and x262 piping tool; continued development of avs4x264mod. GitHub repository
- avs4x264mod - AviSynth to x264 piping tool; continued development of avs4x264 with additional futures and bugfixes.
- avs4x265 - AviSynth to x265 piping tool; based on avs4x264 with some enhancements from avs4x264mod.
- AviSynth Info Tool - This program gathers all available info about the installed AviSynth version. It should be useful for troubleshooting since especially novice users don't always know which AviSynth version they have installed, what DLLs/DLL-versions reside in their plugin directory, etc. The tool also helps resolve problems with plugin DLL dependencies like missing Microsoft runtime libraries.
- AVSMeter - A CLI (command line interface) tool that "runs" an AviSynth script with virtually no overhead, displays clip info, CPU and memory usage and the minimum, maximum and average frames processed per second. It measures how fast AviSynth can serve frames to a client application (x264, for example) and comes in handy when testing filters/plugins to evaluate their performance and memory requirements.
- avs2bdnxml - AviSynth rendered subtitles to BluRay SUP/PGS and BDN XML.
- AVSLib - General purpose toolkit/extension library enhancing AviSynth's ability to perform complex linear and non-linear video editing tasks. Includes support for Array containers & operators, debugging tools, math & string functions, filters and many more.
- avsutil - AviSynth utilities package; it includes avs2bmp, avsinfo, avslint, and avs2wav.
- pipedec - "Pipe Codec" acts as a VFW compressor. When called upon to compress data, it runs an external program, feeds it the uncompressed data on stdin, and sends a dummy compressed stream back to VFW. Download binaries: pipedec.zip
- AviSynthUI - AVISynth UI (no longer developed) is a user interface for the script based video editor AVISynth. Written in Visual Basic, It enables you to edit videos using AVISynth with the comfort and ease of use of having a user interface.
- avs2pipe - avs2pipe is a tool to output y4m video, wav audio, dump some info about the input avs clip or suggest x264 blu-ray encoding settings. GitHub repository. Superseeded by avs2pipemod.
- avs4x264 - AviSynth to x264 piping tool; superseded by avs4x264mod and avs4x26x.
- AviSynth Batch Scripting (GUI) : A batch scripting tool that is not only designed for AviSynth .avs files but you can generate any batch script of any type of file you want, with an easy to use graphical interface.
