There are many ways to convert either DPX or the native 4K h.264 .mov files to 1080p. Most good software will allow you to select the reduction algorithm for best possible results. Personally I use Nuke or Adobe Media Encoder CC or Apple Compressor or After Effects or alternatively you can just set up a NLE timeline for 1080p and scale the clip to fit the sequence - like in Adobe Premiere CC. The quality of the transcode is determined by the scaling algorithm used: Cubic, Lanczos4 or Lanczos6 are good depending on the sharpness you require. You can even use Photoshop CC to import the DPX sequence, downscale using the Bicubic Sharper algorithm and render out a ProRes file.
