Mpeg-2 assets must have the same length and the same frame rate.
From the DVDSP User Manual:
Requirements for MPEG Streams in Multi- and Mixed-Angle Video
The integrated MPEG encoder produces streams that meet the criteria for multi- and mixed-angle use:
With multi-angle tracks, all streams must be the same length. With mixed-angle tracks, all alternate streams in each mixed-angle section must be the same length.
All streams must have the same resolution and frame rate. The length and pattern of GOPs (Group of Pictures) must be the same for all streams (angles). If you are not using the integrated MPEG encoder, use an encoder that allows you to turn scene detection off.
All GOPs should be closed. You will not be able to cleanly switch between the streams if you use open GOPs
- In addition, the DVD specs stipulate a max bitate of 8Mbit/s per angle:
