Anm2Ed (Animation Editor)

A reimplementation of The Binding of Isaac: Rebirth's proprietary animation editor. Manipulates the XML-based ".anm2" format, used for in-game tweened animations.

• Extended version of the original proprietary Nicalis animation editor
  
• Smooth Dear ImGui[github.com] interface; docking, dragging and dropping, etc. You might be familiar with it from Repentogon[repentogon.com].
  
• Greatly polished in many areas, to assist with all your animating needs
  
• New features:
  
  • Additional hotkeys/shortcuts (rebindable!)
    
  • Additional wizard options
    
  • Broadened sound support
    
  • Can output .webm, .mp4, spritesheet, or *.png sequence (wih FFmpeg)
    
  • Cutting, copying and pasting
    
  • Onionskinning
    
  • Robust snapshot (undo/redo) system
    
  • Selecting multiple frames at a time
    
  • Settings that will preserve on exit (stored in %APPDATA% on Windows or ~/.local/share on Linux)

You will need FFmpeg installed! Get it from here[ffmpeg.org] and point to the downloaded ffmpeg executable within the program!
