Written requests

If you want the source on a physical medium, or cannot get it from the links above, email contact@komboklipper.com with the KomboKlipper version you hold. We will send it for the cost of the medium and postage. This offer is valid for three years from the date of the release you hold, and for as long as we offer that release for download.

The FFmpeg libraries ship as separate DLLs in the app's tools folder, so you can replace them with a compatible build of your own.
