FREE Sony Vegas Pro 12 edit software handles XAVC recording format:

The PXW-Z100 uses Sony’s XAVC recording format employed in other CineAlta 4K cameras. MPEG-4 AVC/H.264 compression is used for HD (1920 x 1080), QFHD (3840 x 2016) and 4K (4096 x 2160) content. Image sampling is 4:2:2 10-bit, with an intra-frame system that compresses each frame individually at a maximum bit rate of 500Mbps or 600Mbps during 4K 50fps or 60fps recording respectively and 223Mbps during HD 50fps or 60fps recording. The XAVC format is ideal for those looking to implement a high-quality, secure and worry-free workflow.

FREE Sony 32GB XQD Memory Card:

The XQD Memory Card is a new standard of solid state memory. XQD uses the ultra-fast PCI Express interface and Sony’s unique camera processor to enable stable video recording at 500Mbps or 600Mbps. The PXW-Z100 features two XQD Memory Card slots. Multiple cards can be used in various ways, such as for relay recording. When the first card becomes full, recording continues on the second card without a break.
* XQD cards have a write speed of up to 800Mbps. The use of S Series cards with 180MB/s writing speed is recommended.
