DVD Studio Pro: Requirements for Importing Multi-Segment MPEG-2 Streams

If you intend to import multi-segment streams into DVD Studio Pro, the streams must meet all of the following criteria:

• They must be numbered in sequence by adding a suffix to the filenames, using the form ".1" to ".99" or ".01 to .99", such as:

  filename.01
  filename.02
  filename.03

• Video streams must have continuous timecode. In other words, the timecode for the last frame of the first file must be exactly one frame before the timecode for the first frame of the second file (and so on.)
• The total length of any selected audio streams should match the total length of the video streams.
  

Background

Prior to the advent of the Mac OS Extended (HFS Plus) disk format, Mac OS file sizes could not exceed 2 GB. Consequently, some third-party MPEG-2 encoders create multi-part MPEG streams, with each segment smaller than 2 GB. Now that Macintosh computers come with disks that use the HFS Plus format, it is no longer necessary to split MPEG-2 files larger than 2 GB. However, some MPEG-2 encoders still do this.
