Cineform Neo 4k ?
you mean to try export it with the cineform from gopro?
This is going nowhere. As always, it will depend on what device this is going to be played. just exporting it as Cineform may not be at all of any use. Inquire with the people who ordered it and figure out the details. If this is for cinema, you will have to adhere to the DCI specs and use DPX, JPEG2000 or TIFF image sequences with respective color adjustments and linearization, most likely. For anything else it could be all sorts of things...
