Rendering MPEG-2 for DVDA

kunal wrote on 8/13/2010, 8:53 AM

I have a 1080-60i project that's edited in v9.0. I intend to burn DVDs with DVDA.

Currently, I'm rendering the video mpg2 and the audio ac3 (Pro) from Vegas and importing these media into DVDA and then burning. Is this the right process or should I render the files as part of the DVDA 'prepare' process or it doesn't matter?

Thanks.

I like to do it the way you're doing it. I don't trust, or I'm not secure with, DVDA to make the conversion. For DVD I render my mpg2 and ac3 (pro) from Vegas.

You're doing it the right way.
Don't forget to use the correct AC3 Pro settings:
Dialog Norm at -31 (this sets it at unity gain)
RF and Line Mode DRC Off (WYHIWYG)
DC High Pass Filter On (this operates at <=3Hz and takes DC bias out of the mix)
Bandwidth Low Pass Filter On (this takes aliasing noise at >20kHz out of the encode, but it also lowered the rendered volume by -0.1dB in my tests)
90 Deg Phase Shift On (makes it easier for Pro Logic decoding on older equipment, Dolby says it is inaudible in 5.1 except in "very rare" cases)

Also suggest tha you add Sony Sharpen FX to your video. Leave setting at "0". Somehow it makes a difference in the quality of your SD rendered video.

Thanks for the replies...

One question about audio - is it recommended to render the audio as an AC3 or should I try a .wav? (edit project properties in DVDA to configure audio as PCM Stereo, 24-bit, 48Khz and render from Vegas as a .wav).

My film is only 7 minutes long, so I'm not constrained by space.

Feel free to render a WAV rather than AC3 in Vegas, but I doubt you would notice a difference on a home theater system. Also, 24-bit is overkill if your camera records in 16- or 12-bit.
