Raylight version ² adds support for writing Quicktime files back to a P² card as an MXF file.

It is very important to make sure the P² card is write protected before placing card into any reading device.

If time and space allow, a computer running FCP is placed on the set. After each card is backed up on the P² Store, the

One note about multiple firewire devices: on all Apple hardware, the built-in firewire ports share the same bus. This
means that although you may have multiple FW400 and FW800 ports, internally they are all treated as one bus. For some
applications, splitting your devices amongst USB and Firewire is recommended. For example, if a firewire drive were to
be used for the main capture scratch disk, a USB ².0 connection for a P² card reader would work best. If an AG-HVX²00
handheld P² HD Camcorder is going to be used as a card reader, a USB ².0 hard drive should be used for capture. The
throughput for capture on USB and Firewire are both acceptable for capturing all DVCPRO codecs.
If multiple firewire devices need to be used, such as a AJ-HD±400 DVCPRO HD VTR and a FW hard drive, I recommend a
firewire adapter card. These can be PCI, Cardbus, or ExpressBus in form and provide a reliable way to use multiple devices
on the same computer. Every time the card is ingested, a log note is added and the card can now be erased in the P² Store
