Final Burn Question

[KarlB]

Hi,
I'm sending my film to Disc Makers, so they can make copies of my film. But I want to make certain my film's video and audio is as great as it possibly can be. I thought I'd make a post of what I did, to make certain I did everything correctly. Please let me know. Many thanks!
Here’s how I edited the film:

-The movie was filmed in 24P using a Panasonic DVX100B camera.

-For each individual scene, I edited the film using Vegas 6.0, using a 23.976 (IVTC Film) timeline, with the full resolution rendering quality and the resample & stretch quality set at best. I rendered each individual scene using AVI (NTSC DV 24P, inserting 2-3-3-2 pulldown), with video rendering quality set at best.

-Then I put each individual scene on a 23.976 timeline. I rendered the audio using Dolby Digital AC-3, and I rendered the video using Main Concept MPEG-2. The video quality was set at best, and the constant bit rate was set at 8,000,000 (bps), with the video quality set at HIGH (31). (I'm burning on a HP DVD+R double layer DVD)

-In DVD Architect, I created my DVD menu and burned the disk.

Did I forgegt anything/do anything incorrectly? Any advice would be greatly appreciated Many thanks!

Did you use the DVD Architect 24p template under MPEG-2? That will give you the best results.

Other than that, your workflow seems fine, but you can get rid of a DV generation by inserting your VEG files into the master timeline instead of rendering to a 24p DV AVI. You might have to trim them, though.

Hi, David,



Yes, under MPEG-2, I used the 24P template. I have one question, though. The Disc Makers authoring engineer e-mailed me today and claimed: "8 MPS is too high and might cause some playback problems. We recommend 6.5 MBS. He may also want to consider rendering the film to 29.97. If it’s 24p the DVD player will have to convert it to 29.97 and how good a job it does will depend on each player."

I was always under the impression that 8,000,000 BPS or less would be fine, but as it says above, the Disc Makers authoring director claimed that it's too high and I should go with 6,500,000 bps. Which should I do? Also, should I render 29.97 also, like the authoring director advises?

Many thanks!



Regards,

Karl

I'd go with the variable bit rate already set in the DVDA templates. As for adding pulldown, 99.9% of Hollywood DVDs are put to disc as 24p. Ever seen a problem?

If you put it to disc as 29.97, anyone watching on a progressive display will see interlace artifacts.

Hi, David,


So I should keep my variable bit rate at a maximum of 8,000,000, an average of 6,000,000, and a minimum of 192,000, correct? Should I use the two-pass, as well?
I was skeptical of rendering at 29.97 (after hearing it from the engineer) after filming 24P. So I'm glad you agreed with the MPEG-2 24P template render.
Many thanks!

[David Jimerson]

Just use the 24p template and don't change anything. We've got thousands of discs out there which were rendered that way (and replicated, just like Disc Makers will do), and no one has had any problems.

[KarlB]

Okay, I'll stick to the 24P template (which is 8,000,000 max, 6,000,000 average, 192,000 minimum). So I shouldn't use two-pass with the 24P template?

[David Jimerson]

No reason to. The defaults exist as they are because they're already ideal.

[KarlB]

Awesome. Many thanks!
