About AviSynth+

AviSynth+ processes video through scripts: you describe sources, filters and edits in a text file, and programs such as encoders read the result as if it were a normal video. It is fully compatible with plugins and scripts written for the original AviSynth.

Compared with AviSynth it adds a 64-bit version, multithreading, high bit-depth pixel formats, faster core filters, loops and arrays in the script language, and native support for Unix-like systems and ARM. Arch Linux and Debian packages are available.

Strengths

  • Compatible with existing AviSynth plugins and scripts
  • 64-bit and multithreading support
  • High bit-depth pixel formats

Limitations

  • No graphical editor; work is done by writing scripts
  • Requires other programs to encode or view the output
