Panasonic AJ-HPM200 Operating Instructions - Page 17

Introduction ■ Connecting a P2 Card Camera A P2 card recorded in a P2 camera recorder plugs directly into a PC card slot in this unit for immediate access. The P2 card is a semiconductor memory card that Panasonic developed for professional AV use. ■ AVC-Intra standard feature The AVC-Intra codec is provided as a standard feature. An Intra-Frame compression format based on the H.264 video compression standard makes possible a high compression rate and high-quality image. The AVC-Intra codec for this product is compatible with the following two formats. AVC-Intra 100: High-quality video supporting full-bit HD AVC-Intra 50: Low-rate and low-cost operation During native recording at a 59.94 Hz or 50 Hz setting in setup menu No. 25 (SYSTEM FREQ), the unit produces pull-down output.

It also up-converts composite and SD-SDI input signals to record in the same HD format as the system. ◆ NOTE: • The cross converter function is not available during up-conversion recording. • SD closed caption signals during up-conversion recording are recorded in the 608 HD (VANC) signal format (59.94 Hz only). • Closed caption signals are not output during playback or down- and cross-conversion. • Nor are closed caption signals output during playback of upconverted SD signals. ■ Frame rate conversion Recording input from variable frame-rate cameras at 24PN (Native), the unit is also capable of playing back cards recorded at 24 fps and converting the output to 1080/24 PsF. It can also record input from a variable frame-rate camera at 25PN (Native). ◆ NOTE: • Do not use cards that have been edited or contain clips shot in different formats as the loss of management data may prevent normal playback. ■ Native recording The unit provides support for native recording, a mode that records only active frames. This provides longer recording time when a VariCam, AJ-HPX2000/2100 or AJ-HPX3000 is connected to the HD-SDI IN connector. Variable frame rate (VFR) recording becomes possible by connecting a VariCam. ● Native recording defined Native recording extracts only the active frames during 1080i AVC-Intra recording as well as 720P DVCPRO HD and AVC-Intra recording. At 720P, this lengthens the recording time 2 to 2.5 times over pull-down recording. 2:3 pull-down Active frames Native recording A BB CD D D A B C D ■ Thumbnails for managing clips visually The 9-inch color LCD monitor displays video clips (thumbnails) stored on a P2 card. The viewer can select the thumbnails he wants to see and change the order in which they appear. Clips can be selected from the thumbnail list for immediate playback. The list also provides quick access to other clip management operations such as copying and deleting, adding shot marks and text memos as well as confirming and editing clip data. ■ Expanded high-speed hard disk interface ● High-speed eSATA interface The unit now supports hard disks using the eSATA interface, which is faster than the regular USB interface. This interface provides faster backup of video data on a P2 card to hard disk and can restore hard disk data to a P2 card. ● Playback (best effort) and playlist editing of hard disk video data Video data on a hard disk can be viewed as thumbnails or a smooth *1 video stream. A protective feature ensures a continuous audio output even if reading performance drops due to use of a slow hard disk or through interference such as vibrations. Playback of hard disk video data *1 enables editing of video on a hard disk in the same way as editing video on a P2 card. Playback *1 of hard disk video data enables direct editing. *1: This does not guarantee playback without frame skipping. Introduction: Features 17
