Sending Video Files

*** All audio must be in compliance with the loudness control practices contained in “ASTC A/85: Recommended Practice” and be set for -24 LUFS.

NOTE: LUFS IS A DIFFERENT METERING SYSTEM THAN DB. BASICALLY IT WILL LOOK AT THE COMPLETE AUDIO TIMELINE AND LIMIT IT BASED ON IT’S METERING FINDINGS. A BALL PARK VALUE ON A DB METER IS AROUND -12 DB (LOWER IF THE AUDIO IS HIGHLY COMPRESSED). IF YOU DO NOT KNOW HOW TO SET AUDIO FOR -24 LUFS THEN SEND .MOV OR .MP4 NON-CLOSED CAPTION FORMAT.
