No, this is not possible. For what it's worth if you are using XDCAM Transfer you are getting the files in their native XDCAM codec with no additional compression. All the transfer application does is change the file wrapper from .mp4 to .mov. Apple or anyone else reading the files then decodes them natively. If you think you are seeing problems with the footage please feel free to reach out to our operational support team @ 800 883-6817.
