I built a Mac app that finds duplicate videos other tools miss

Hey PH!
I'm a solo developer, and I've been working on Dup a macOS app that finds duplicate photos and videos using perceptual hashing.
The problem I kept hitting:
I had 200GB of media scattered across folders exported at 4K and 1080p, converted MOV to MP4, shared via AirDrop (which renames files). Every duplicate finder I tried said "no duplicates found." They only match identical files.
What Dup does differently:
Instead of comparing file names or raw bytes, Dup compares what your files actually look like. Same vacation video at 4K and 1080p? Different codec (H.264 vs ProRes)? Renamed after AirDrop? Dup catches all of it.
I tested it against a popular paid tool on the same 200GB folder:
- Other app: 3 duplicates found
- Dup: 47 duplicates found, 38GB recovered
How it works:
- Perceptual video hashing (two-pass with duration verification) built in Rust
- Perceptual image hashing for photos (handles HEIC, RAW, JPEG)
- 100% local processing nothing leaves your Mac
- Free to scan, Pro for unlimited cleanup ($14.99/yr)
I'd love feedback on:
1. Is the video dedup angle compelling enough to stand out in a crowded market?
2. Any features you wish duplicate finders had but don't?
3. Would you pay for this, or expect it to be free?
