A: The DVRex is a hardware and software CODEC product. Hardware CODEC products not only work in DV but also capture and output analog. This is very useful for video producers who have a lot of "legacy" material sitting on an analog tape. With hardware CODECs you can combine old and new material and output the final production in DV or analog.

From a rendering speed point of view, hardware and software CODECs both use the computer CPU to render transitions and special effects. In the case of the DVRex, an MMX optimized software CODEC has been developed which has shown to be 25% faster than the fastest PC CODEC on the market. The DVRex software allows you to choose the CODEC you use for rendering.
