*From Table 123
warnings should be authored as timed stills, which have no impact on disc space Subtract the total size of ancillary material from the disc capacity minus overhead This gives remaining capacity for the main program Calculate the average video bit rate for the main program by dividing the remaining capacity by the running time Also calculate the maximum video bit rate by subtracting the combined audio and subpicture bit rate from 1008 These numbers will be fed into the encoder when compressing the video for the main program Note that minor elements such as subpicture tracks and motion menus are usually so small that they can often be omitted from calculations If they were left off of the example in Table 124, the average data rate would come out to 417 Mbps, which is close enough An alternative bit budgeting approach is to divide the disc capacity (in bits) by the total running time of all segments (in seconds) to get the aver-

age data rate (in Mbps) Adjust up or down for quality of different programs as needed For each program, subtract the combined data rate of its audio and subpicture streams to get video rate It s a good idea to follow up by summing the sizes of each segment (including audio) to check that the total doesn t exceed disc capacity Tips and Tricks The following list of tips will help you in balancing the bit budget:
Don t forget motion menus and menu transitions Don t forget to leave room for any added PC content A few programs or HTML files are not worth worrying about, but large multimedia applications and installer packages need to be accounted for Each camera angle increases the data; two camera angles double it, three angles triple it, and so on Reduce the maximum data rate according to the number of angles (see Table 634) If you have two or more programs that contain much of the same data, consider using the seamless branching feature to combine the duplicated segments Still images take up so little space that you don t need to include them in your calculations Unless you are including more than four subpictures, you may wish to omit subpictures from the calculations, since the space they take up is negligible
Asset Preparation
A typical project requires dozens of assets from a variety of sources A complicated project may require thousands (see Table 125) Each asset must be properly prepared before it can be fed into the DVD authoring process The following sections cover the details for preparing each type of asset
Preparing Video Assets
The final quality of DVD video is primarily dependent on three things: the condition and quality of the source material, the visual character of the material, and the data rate allocated to the video during encoding The better the quality of the source, the better job the encoder can do Always use the best quality source Insist on a digital copy whenever possible, such as D1, or Digital Betacam Beta SP will do in a pinch, but in many ways it is inferior to DVD s capabilities
