There are several different levels of quality control, or QC, in the post production process. The most detailed and intensive of these is 100% QC, which is a thorough and complete review of the tape or video from start to finish, and encompasses all aspects of quality control. 100% QC typically takes between two to two and a half times the total length of the video to complete. In other words, in order to 100% QC a 1 hour video, you should expect to spend about 2 to 2.5 hours.
There are several steps to the 100% QC process:
- This one seems obvious, but make sure that you are reviewing the correct project. Check to make sure that all of the barcodes and titles match.
- Spec check. Check all of the specifications of the project, including channel conditions, luminance, Chroma levels, horizontal blanking, vertical blanking, etc.
- Check program for problems. Note any problems with the video or film, make notations of any audio/visual levels that are out of specification, ensure that all text is located within the safety box, and note any additional audio or video issues that will need to be addressed.
- Complete report. Give the report a pass, fail, or hold recommendation. If the project does not pass, be sure to include notations and suggestions for edits to fix any problems found.
There are broadcast standards in place to measure sounds and audio in video. When measuring loudness, there are three measurements to be aware of: LKFS, LUFS, and LU. LKFS and LUFS are essentially identical, despite having different names. LUFS is an absolute measure, and depending on which broadcast standard is being used, the target loudness level could be, for instance, -23 LUFS.
The Harding Test is an automatic test for Photosensitive Epilepsy triggering image sequences in broadcast video content. This test is designed to analyze video content for stationary of flashing patterns that may trigger seizures or cause harm to people suffering from photosensitive epilepsy, or PSE.
5.1 is a common term for the six channel surround sound audio systems. 5.1 is currently the most commonly used layout in both commercial applications, such as a cinema or theatre, and residential applications, theater room, living room, etc. It is comprised of five full bandwidth channels, as well as one low frequency channel. Dolby Digital is a common 5.1 system. All 5.1 systems are similar in their setup, and consist of a front left and right, a center channel, two surround channels, and a subwoofer.
Discrete audio channels refer to multichannel audio or soundtracks being stored, with all of the specified channels being isolated from the other. This is stark contrast to matrixed audio, where multichannels are blended.
