Are you thinking about doing field capture with a laptop, or editing on the go with a laptop-based system? The HDX-SDI connects to a Mac or PC notebook via an included ExpressCard adapter, but it is also available with a PCI Express card for operation with today’s ultra-fast multi-core Mac and Windows towers.
Most current-generation high-performance PC laptops, including Apple MacBook Pro computers, are equipped with ExpressCard slots. On these portable systems, the HDX-SDI gives you broadcast-quality capture and monitoring. With the enormous performance gains seen in laptop technology, these compact computers are now powerful enough to easily capture and play back both HD and uncompressed SD video. You can essentially build a complete capture/edit system that fits in a backpack.
There's another major benefit for using ExpressCard connectivity to a laptop for video I/O: doing so frees up the FireWire port on your laptop for professional-grade video storage solutions, which offer enough storage space and access speed to support the most demanding HD and uncompressed SD workflows.
