The headline for these cameras is the new codec that they’ve developed – 4:2:2 MXF @ 50mb/sec. What does that mean for you? Better HD video that you would get with HDV level products.
Canon has gone out of the way to see that this new codec is supported by Apple, Avid, Adobe and others. The 305 add HD-SDI, genlock and timecode I/O. It records onto Compact Flash media, giving you up to 160 minutes at 50mb/s on a 64GB card.
