In the international co-production of HD (high definition) programs, there are some problems in post-production. These problems originate in the frame-rate relationship between 24p and 23.976p. Generally, 23.976p shooting is used to ensure compatibility with TV systems such as NTSC, but some problems occur when transferring to the PAL system or films. In this study, in a co-production with China called" The Ancient Routes of Tea & Horses', we accomplished 5.1 surround sound which was compatible with both 24p and 59.94i HD images. This paper describes the production techniques and problems, and some future challenges. We believe the techniques will be useful for media combinations in the future.
