tips on rendering audio in Vegas Pro 10
Hi, I rendered a amateur film in Vegas Pro 10 and burned it on a Blu-Ray disk.
The audio is 5.1 surround sound and is comprised of 12 audio tracks on a singular bus, 4 from the video itself and 8 additional tracks for sound effects and music sound track. The video audio tracks were left to their default surround pan, the sound effect tracks had various panning settings and the music track was set to front left and right
The audio was rendered in ac-3 pro 5.1, bitstream mode set to Complete Main, 3/2 coding mode, 48kHz, 448 kbps, -27db Dialog normalization. The Dynamic range compression was set to none and the 3db attenuation was enabled on Surround channel processing.
– Once burned to Blu-Ray, I notice a slight but very audible dip in the music soundtrack whenever a particular sound effect is heard throughout the film. I double checked the music track volume envelope in those areas and it’s as straight as an arrow throughout.
Anybody have any idea as to why?
– Next, when you put a music soundtrack like I have in your 5.1 surround sound project, is it preferable if it’s heard from both the front and rear speakers or just the front L/R? This is not a live concert, the music is for atmosphere only. And if set only to front L/R, should the pan be set in the center or at the front between the left and right speaker?
– Also, should the sound effect and music audio tracks each have a duplicate LFE only track for low frequancies?
And finally, if the film is to be played on both 5.1 and 2 speaker setups, is it better to render both a 5.1 track and a stereo track and set it in DVDA so that the viewer can select the proper audio setting in the setup menu or just render a 5.1 track and let the Blu-Ray player downsample the audio to stereo?
Thank you very much for any assistance.
