Hi Philipp,
For now, it is not in our pipeline to implement the possibility of shooting in the RAW format (or JPEG+Raw), as it is still not compatible with our software. We understand your need and pass your request on to the product development team.
Please consult the more recent community topic about capturing RAW imagery: Pix4DCapture Collecting Raw Imagery. Also, do not hesitate to share your experience with the other users.
We will now close this topic for comments, Thank you for understanding.
