+The Python package for near duplicate video detection
+
+Videohash is a for **detecting near-duplicate videos (Perceptual Video
+Hashing)**. It can take any input video and generate a 64-bit
+equivalent hash value. Videohash is way more faster than comparing the
+imagehash values of individual of the video and more reliable than
+hashing.
+
+The video-hash-values for identical or near-duplicate videos are the
+same or similar, implying that if the video is resized
+upscaled/downscaled, transcoded, watermark added/removed, stabilized,
+color changed, frame rate changed, changed aspect ratio, cropped,
+black-bars added or removed, the hash-value should remain unchanged or
+not vary substantially.
