Need a quick help! export dvd PPRO

Hi all,

I need a quick help!

I want to export a 23min. short (audio 48mhz) to dvd in Premiere PRO 1.5. I want the best possible dvd for a screening. I used the AG-DVX100 25P PAL progressive mode. Need some help! Thanks!

1. Used this link http://www.customflix.com/bitbudget to calculate the bitrate:
Media type: DVD-R
Main audio track: PCM
Secondary audio track: none (I have more audio timelines in my project but it’s 1 audio track, isn’t it?)
Duration: 23min.
Recommended encoding mode: CBR
Average video bitrate: 4.96 mbps

Questions:

1. I understood VBR is a better option, recommended here is CBR, can CBR also give the best possible result? Also with progressive footage?

2. Average video bitrate: 4.96 mbps. What to do in edit settings with: Target bitrate, Maximum bitrate and Minimum bitrate? (now it’s standard 4.0, 7.0 and 1.5). Where to put this 4.96 mbps, Target bitrate or Maximum? (I’m really a PPRO beginner, sorry)

3. I always understood that max. bitrate is the best, so at 9.0. Or gives the average video bitrate as calculated the best result for screening my 23 min. short?

4. should I do something with M frames and N frames?

Thanks for answering!
 
Personally, I would go with a high bitrate CBR setting. VBR can be more efficient bitwise which means you can fit more material on the DVD while maintaining a high quality image. Since you should have no problem with running out of space on the DVD, I would go CBR. 9 mbps is theoretically the max but that INCLUDES the audio bitrate. PCM audio requires a lot more bandwidth than AC3 Dolby which in turn significantly reduces the bandwidth for video. Using the bitrate calculator you referenced, just changing the audio from PCM to AC3 changed the recommended video bitrate to 6.3 CBR.

Unfortunately, using Premiere to burn the DVD only provides the option for AC3 audio if you purchase the Surcode plugin (which is grossly overpriced, IMHO).

If space is not a problem on the DVD, I use a high-quality 6.8mbps CBR setting and convert the audio to AC3 in Encore for the DVD. Before I started using Encore, I used PCM audio and encountered some DVD players that would choke on the PCM bandwidth even though the total bitrate was way below the max. These were not cheap, low-end DVD players either.
