Duplicates in the System

It looks like 2@ is Pixmac

Hey everyone!

The 2@ and 4@ prefix (there's also a 3@) are all from our partnered libraries. That's why you're seeing duplicates. If someone has stuff on YayMicro, FeaturePics, or Pixmac, then they're also going to show up on Pond5 with the prefixes.

We don't have 123rf's library anymore.

If you have duplicates online, please don't hesitate to email me at ryan@pond5.com and I will be more than happy to take down any partnered content.

Cheers,

Ryan

you should add an md5sum or SHA1 for all of your thumbnails and footage, and have your partners do the same, then dedupe it in your search database, and it will solve this problem.

make sure you either use 2 checksums or 1 checksum and file size, in case you get a dupe checksum from 2 different clips.

use md5 or sha1 so you and your partners all have a standard checksum. you can write your own, and skip bytes in the larger files, but then you'd have to share your algorithms with your partners and there is more room for mistakes.

luckily you only need to compute the checksum 1 time.

and it will prevent duplicate uploads.

you must be using checksums because you send notices of duplicate uploads.
