Chapter 3 Recording and Playback Recording This section describes video and audio recording on the unit. See page 88 "Function Menu" in Chapter 6 for more information about function menu operations. See page 105 "Setup Menu Operations" in Chapter 6 for more information about setup menu operations. Note It is not possible to combine material recorded in different system frequencies and audio recording formats on a single disc (although different bit rates may be combined). If you attempt to record material in a system frequency or audio recording format that differs from that of existing recorded material on the disc, "REC INH" appears on the display and recording is inhibited. Make the following settings and adjustments before starting to record. Recording format settings: See the next section "To set the video and audio recording formats". Video input signal selection: Select with V INPUT on the HOME page of the function menu. Audio input signal selection: Select with A1 INPUT to A4 INPUT on the HOME page of the function menu. Timecode and user bits settings: See "Recording Timecode and User Bit Values" (page 46). Selection of time data to display: Select with CNTR SEL on page P1 of the function menu. Selection of audio channels to monitor: Select with MONI CH and MONI SEL on page P1 of the function menu. Volume adjustment of the monitor audio: Adjust with the LEVEL knob. Remote/local setting: Set the remote control switch. If you set it to REMOTE, also set the setup menu item INTERFACE SELECT >REMOTE I/F ("REMOTE" and the connector used appear on the display). To set the video and audio recording formats To set the video recording format Set the video bit rate (compression method) by setting OPERATIONAL FUNCTION >REC FORMAT in the setup menu to one of the following. Menu setting/display HQ Video bit rate VBR 35 Mbps Menu setting/display SP LP DVCAM a) Video bit rate CBR 25 Mbps VBR 18 Mbps 25 Mbps a) Appears only when the PDBK-104 option board is installed. To set the audio recording format Set AUDIO CONTROL >REC MODE in the setup menu to one of the following. Menu setting Display 2ch×16bit 4ch×16bit 2CH 16BIT 4CH 16BIT Audio recording format 2 channels/16 bits 4 channels/16 bits Note When the video recording format is set to DVCAM, the audio recording format is always 4 channels/16 bits, regardless of the setting of this item. Recording Timecode and User Bit Values There are the following four ways of recording timecode: Internal Preset mode: This records the output of the internal timecode generator, set beforehand to an initial value. The following run modes can be selected. • Free Run: Timecode advances continually. • Rec Run: Timecode advances only during recording. Internal Regen mode: This records the output of the internal timecode generator, initialized to timecode following continuously upon the timecode of the last frame of the last clip on the disc. External Regen mode: This records the output of the internal timecode generator, synchronized to an external timecode generator. As the external input, the timecode input to any of the following connectors can be selected. • TIME CODE IN connector: TC • HDSDI INPUT connector: LTC • SD SDI INPUT connector or COMPOSITE INPUT connector (when PDBK-104 is installed): VITC • SD SDI INPUT connector (when PDBK-104 is installed): LTC External Preset mode: This directly records the input of an external timecode generator. As the external input, the timecode input to any of the TIME CODE IN connector can be selected. 46 Recording
