M em or y C a r d Rec o rdi ng The file-based recording system and digital interface achieve a comfortable 3D image production workflow File-Based Recording to Two Memory Cards Using the two Left/Right memory card slots, the AG-3DA1 records left-channel and right-channel full-HD images simultaneously to two SD/SDHC Memory Cards. The solid-state memory card ensures high reliability and withstands operating temperatures of -25°C to 85°C (-13°F to 185°F). This enables use in harsh temperatures and fluctuating humidity. It is also free of dropouts and head clogging. With memory cards, there is no need to search for a blank space to record. Data is automatically recorded in an available space. This eliminates accidental overwriting of existing data. After shooting, recorded clips can be previewed or deleted immediately. After recording, data can be uploaded to editing software without digitizing. SD/SDHC Memory Cards are inexpensive and can be easily purchased in local markets. * Use SDHC/SD Memory Cards of Class 4 or higher. SDXC cards cannot be used. AVCHD PH Mode for FULL HD 3D Recording The AG-3DA1 records in AVCHD PH mode, based on MPEG-4 AVC/ H.264 High Profile, which is the latest video compression technology. With more than twice the compression efficiency of MPEG-2 (such as in HDV), AVCHD provides both high image quality and a low data rate. PH mode was developed by Panasonic exclusively for AVCCAM professional video production. Boasting 24 Mbps (average: 21 Mbps), which is the maximum bit rate for the AVCHD format, the AG-3DA1 records 1920 x 1080 full-pixel HD images. The multi-slice feature of the PH mode also helps to speed up processing by nonlinear editors that are equipped with multi-core CPUs, by using parallel processing to take full advantage of the CPU power. HD Multi-format Recording Multi-format HD recording in the AG-3DA1 responds to a host of 3D content production needs and worldwide applications. It supports the following HD video formats. The maximum recording time is approximately 180 minutes in each mode (when two 32 GB SDHC cards are mounted in the Left/Right slots). AG-3DA1 series Recording Format • 59.94Hz mode: 1080/60i, 1080/30p (over 60i), 1080/24p (native*), 720/60p • 50Hz mode: 1080/50i, 1080/25p (over 50i), 720/50p * In Native mode, the AG-3DA1 records only active frames. Sample comparison: When a flash causes large contrast differences and reduces correlation of consecutive image, HDV shows considerable block noise, while AVCHD in the PH mode minimize break-up.
