Dup
Same video · ~94%
Dup samples frames throughout each video and creates a visual fingerprint. Same footage matches regardless of codec, resolution, container, or file size.
Can it find similar videos, not just exact copies?
Yes. Dup uses perceptual video hashing to compare what your videos look like, not their raw file data. It finds duplicates across different codecs (H.264, H.265, ProRes), resolutions (4K, 1080p, 720p), containers (MOV, MP4, MKV), and file sizes.
