bitrate calculation

	bitrate calculation by Pikea Manley on Oct 30, 2009 at 9:07:35 pm I rendered a 1:52:01 video in AAC and MPEG formats. It's clocking in at over 7 Gigs. Need to get this on to a standard 4.7 DVD. Does somebody have some handy bitrate calculator? Best wishes, Pi Respond to this post   •   Return to posts index

	Re: bitrate calculation by Mike Kujbida on Oct 31, 2009 at 1:45:40 am As usual, Grazie's right. I've been using that calculator for several years now and it's never let me down. A few suggestions for you. In spite of what the calculator says, never go over 8,000,000 for a MAX value. Burned DVDs (what we create) can have problems on some players if you exceed this value. Always use name brand media with Taiyo-Yuden and Verbatim being the most recommended brands. If the project is under 70 min. long, use a CBR of 8,000,000. If it's longer, use the calculator to find the proper VBR numbers. If the video is of even slightly marginal quality (poor lighting, etc.), do it as a 2-pass. This will take longer to encode but the result will be worth it. Lastly, I get the following numbers for your project. 8,000,000 / 5,040,000 / 3,024,000 Respond to this post   •   Return to posts index

	Re: bitrate calculation by Pikea Manley on Nov 1, 2009 at 8:23:17 pm Thanks, guys. This whole digital media thing is killing me. I got totally different responses with my attempts at the calculator and just don't understand the process. I'm reading through the documentation on the calc and trying to figure out what it all means, but using Mike's calcs for a new rendering and just sort of hoping it works out. Thanks for taking the time to help the newb. This is my third martial arts instructional project and my longest by 40%. Respond to this post   •   Return to posts index

	Re: bitrate calculation by Pikea Manley on Nov 3, 2009 at 4:37:20 am Yikes. 4.6 gigs. I've been trying to duplicate your calcs with the calculator and I guess I'm missing something here. Can you perhaps through me an assist and help me get it down to about 4.4 so I can get the theme song in there? Thanks guys! Respond to this post   •   Return to posts index

	Re: bitrate calculation by Mike Kujbida on Nov 3, 2009 at 12:43:39 pm Pikea, unless you have some motion menus in your project that you haven't mentioned, the numbers I gave you should work. BTW, this assumes AC3 audio as a WAV file would be far too large for a project of this length. To be on the really safe side, bump it up to a 2 hr. DVD and use the following settings: 8,000,000 / 4,688,000 / 2,808,000 Respond to this post   •   Return to posts index
