Isn MPEG encoding slow? What does DVD Studio Pro do to increase encoding speeds?
Software-based MPEG encoding has traditionally been a very slow process, taking between 30 and 50 times the length of the source video material. DVD Studio Pro speeds up the process substantially. Included with DVD Studio Pro is Apple’s MPEG Encoder plug-in, which is optimized for PowerPC G4 processors with Velocity Engine. This plug-in produces high-quality MPEG files but takes only about 3 times the length of the source video material. If you need higher throughput, hardware-accelerated MPEG encoders that work in real time are available separately.
