I had to send a story I had shot back to my client via the satellite using SDI.

The vision went well, and the audio was recorded perfectly, BUT I have had to resend the files via FTP as the audio levels were too LOW to be usable.

The SDI facility has audio in, which is taken directly from the audio line out on the camera, and the vision is uploaded into the big wok via the SDI box.

Any ideas on the low audio level?
