• Avisynth version 2.5
  • General purpose scripting tool for reading and processing videos
  • Allows filters to be bound in to compute distortion, add noise, watermarks, etc.

Useful avisynth filters:
		Compare - Compare two videos and Calculate Y-PNSR for each
frame
		This is included as one of the core avisynth filters
Compare(clip_filtered, clip_original, "channels", "logfile") 
		
		SSIM - Compare two videos Calculate Structure Similarity
Metric for each frame
		http://avisynth.org/warpenterprises/
	SSIM (clip1, clip2, "results.csv", "averageSSIM.txt", lumimask=true)
		RawSource - Read in Raw YUV video files
