Hi @Jesse Cappe,
the Canon C70 requires 33x33x33 CUBE LUTs. ImpulZ LUTs have 32 or 64 patch density so they need to be converted. You can use Davinci Resolve or Adobe Photoshop to do that quite easily. (Let me know if you need guidance for either software)
To install the 33x33x33 LUT to your Canon C70 simply store it in the root directory of the SD card you're going to put into the camera.
