HVR-M25 & HVR-M15 COMMON FEATURES

Down-conversion Playback Capabilities

The HVR-M25/M15 can convert material from 1080i down to 480i and 576i, and output these video signals through its i.LINK interface. In addition, these signals can also be output via the VTR’s HDMI (on the HVR-M25), analog component, S-video, or composite connector. This allows users to edit recorded material with a compatible nonlinear editing system using current DV editing software, as well as record SD signals to an external VTR. Video material can also be down-converted to 480P and 576P (as well as 720P on the HVR-M25), and output via the VTR’s HDMI (on the HVR-M25) or analog component video connector.

When down-converting these signals, the aspect ratio displayed can be converted from 16:9 to 4:3. Display modes can be selected from Squeeze, Letterbox*5, and Edge Crop.

i.LINK Interface

The HVR-M25/M15 is equipped with a 4-pin i.LINK interface. This allows for one cable digital transfer*6 of video, audio, and command signals to a compatible connected VTR or nonlinear editing system in HDV, DVCAM, or DV format.

Time Code Copy from External Devices

When the HVR-M25/M15 records signals from the i.LINK port, the time code that was recorded on the original tape can be copied onto other tapes, along with the video and audio signals. This is effective when downloading edited material from nonlinear editors or creating dubs from other VTRs.

Edge Crop Adjust (HVR-M25 only)

When down-converting signals in the Edge Crop mode, the Edge Crop Adjust function is provided to adjust the edge crop position. By displaying the edge crop marker on the LCD monitor, operators can conveniently check the edge crop position before outputting down-converted signals.

Auto Repeat and Custom Repeat

The HVR-M25/M15 has a convenient auto repeat function. This enables the VTR to automatically rewind the tape to either the beginning of the tape, the first complete blank portion, or an index point on the tape, and start playback again from there*7. In addition, the HVR-M25 has a Custom Repeat function that allows operators to set the number of repeat playbacks, the interval between each playback, and the hour at which the playback should begin.

Color Bar and 1-kHz Audio Tone Signal Output

The HVR-M25/M15 can output three types of color bar via the i.LINK, HDMI, analog component, S-video, and composite connectors, as well as an audio tone signal of 1 kHz via the i.LINK, HDMI, and analog audio connectors. These are useful when checking the system conditions.

External Control

The HVR-M25/M15 comes equipped with a Remote CommanderTM unit, which enables users to control the recorder’s functions wirelessly. In addition, the HVR-M25/M15 is equipped with a LANC terminal, as well as a Control S terminal to connect with the optional DSRM-10 Remote Control Unit for jog and shuttle operation.

Tape Cleaner for Reliable Operation

The HVR-M25/M15 incorporates a tape cleaner that adopts a high-grade sapphire blade. This cleaner can help prevent signal dropouts and improve the reliability of recording and playback by cleaning away particles from the tape during operation.

*5 When outputting down-converted signals in the 4:3 aspect ratio via an i.LINK connector, the Letterbox mode cannot be selected. *6 Insert and assemble editing using HDV material is not recommended with the HVR-M25/M15. When video programs in the HDV format are transferred via the i.LINK interface and edited, transitions from

4cut to cut may not be smooth. *7 The HVR-M25/M15 ignores any blank or index point in the first 20 seconds of the tape.
