An audio technician then invited the group to his little kingdom where he takes the audio mixes from the system and compresses them for use on the DVD. Interestingly, unlike the video streams, audio streams are compressed in real-time, something that is currently impossible in the video domain due to the computational power required. These audio preparation rooms are fully equipped to handle a variety of formats and as we informed you earlier, Columbia is also preparing their first DTS titles there at this point, including the DTS version of “Men In Black.” Calibrated, perfectly muffled for the best possible acoustic reproduction, the audio tracks are treated with the same importance at Sony Pictures as the video. The audio is cleaned up entirely to make sure it stands up to the listening environment of a home theater and the studio also makes sure to use re-mixes of the soundtracks that have been prepared for near-field listening. Since big movie theaters have a very different acoustic behavior than home theaters and living rooms, this ensures that the movie has a balanced mix for the DVD presentation that has been adjusted for that particular presentation. Only very few studios, including New Line Home Video, go through this process currently, but the result is more than obvious, as these corrected mixes do not have the imbalance between effects, music and dialogue found in many directly converted releases. Once the disc is finished and assembled, the DVD Center uses emulators to test the disc. These hard disc based emulators avoid the need to burn DVD discs to test the product and as such allows for much faster turn-around times. In rigorous quality assurance programs the disc is then tested with these emulators thoroughly. Every button, every menu entry and every switch is checked, while every line of text on the screen is proofed. Since the DVD Center is also working on international projects it is important to have international and multilingual staff members here, who can truly evaluate the product. It may be a tedious process and I am sure most of these QA folks can’t stand to see the movies they’ve been working on for a couple of years after watching the movie so many times with subtitles and multiple language tracks on. Remember, Columbia discs oftentimes have 6 or more subtitle tracks, all of which have to be checked, as well as numerous audio tracks. For European releases, the number of subtitles and audio tracks can literally explode! One the project makes it through this stage of QA successfully, physical discs are burned and re-checked on a large number of player models to ensure compatibility. |
