Used in OB vans, on desktops and in studios, this mobile recorder is ideal for news gathering and countless other applications. Now the P2 Mobile has evolved further, adding a host of new functions highlighted by network compatibility.
It connects to the Internet, allowing file transfer without a PC. For high-image-quality recording, it comes standard with AVC-Intra, the latest broadcast video codec. The upgraded AJ-HPM also features an enhanced playlist function with easy, intuitive operation, and a newly evolved editor graphical user interface GUI that also improves ease of use.
Providing powerful support for P2HD recording, field editing, HD news flash broadcasting through file transfers, data backup and more, the AJ-HPM is a high-speed, high-image-quality solution to a wide range of broadcasting and video production needs.
In AVC-Intra mode. Play back is based on a best-effort basis. Panasonic does not guarantee smooth playback without frame drops. It uses an intra-frame compression system to bring important advantages to professional editing. It captures master-quality video for high-end video production.
It can also up-convert SD input for recording in HD, and it features an aspect conversion function. The closed caption signal is not output on SDI during up-conversion, down-conversion or cross-conversion playback.
Settings must be made on the menu screen system frequency mode. Output is produced only when the playback system frequency is set to REC mode and gamma curve into video images with a film-like tone. The built-in monitor lets you check the VFR effect during playback. I-Frame Only compression, which completes all processing within each frame, and Long GOP compression, which processes across multiple frames.
When the images of adjacent frames are similar, Long GOP compression achieves an advantageously low bit rate. However, this trait is not often seen in broadcasts like fast-action sports, and music shows with confetti and electronic displays. Also, because processing is performed frame-by-frame in I-Frame Only, new-generation multi-core CPUs offer high-speed parallel processing.
This makes I-Frame Only compression more suitable for nonlinear editing than Long GOP, for which parallel processing is difficult due to its inter-frame dependence. With its I-Frame Only compression, AVC-Intra produces remarkably stable images that are unaffected by adjacent frames, and meets professional needs in virtually all situations and workflows.
Its two methods are particularly effective for boosting compression efficiency. Intra-frame predictive coding intra prediction This process generates predictive images based on adjacent blocks of 8 x 8 pixels.
Selecting the most suitable predictive mode from among nine luminance signal modes see illustration and four color signal modes, it generates accurate predictive images. The residual data obtained by subtracting a predictive image from the original input image is recorded together with the predictive image. This process is conducted within the frame, so prediction accuracy remains high even with fast-motion images.
MPEG-2 uses a fixed table when performing the VLC coding, with the result that compression efficiency is low with some types of images.
In context-adaptive coding, on the other hand, operation varies with different kinds of images and high compression efficiency is maintained at all times. Its rugged design withstands even harsh professional use.
It is highly resistant to temperature fluctuations, dust, impact and vibration, and is free of the problems that are common in tapes, such as condensation, head clogging and dropouts. The P2 card promises solid reliability and excellent mobility under the often difficult conditions of field recording.
Because data is automatically recorded in blank card spaces, there is no need for cueing and the risk of accidentally overwriting valuable data. Or, you can mount five P2 cards, and output the playlist editing result to a sixth P2 card. The P2 cards can be replaced while recording. Endless recording can be achieved if changing the occupied card to the blank card continuously. During Playback, if a new P2 card is inserted, it will be automatically recognized and played back without a break.
This function continuously records video data onto available two or more P2 cards. When the cards become full, older data is deleted to free up the recording area,to result in loss-less and endless recording. When used with cameras for time-sensitive information gathering like weather news reporting, the loop rec function holds the latest video data for a predetermined time period. P2 records a scene as a clip file. To play back or delete a clip, or to check and edit its metadata ja-hpm110 information or add or delete a shot marker, just select the clip from the thumbnail display on the built-in The multiple card slots let you copy clips from one P2 card to another.
At a desired location within a clip, you can change the thumbnail to a different image.
Panasonic AJ-HPM110 User Manual
When recording or previewing a clip, you can attach a memo similar to a bookmark at a desired location up to locations on a frame basis. The simplified editing function lets you copy a segment between memos and create a new clip. Text information can be added to a memo. During or after recording, you can mark each clip with OK, NG or other designation. Example of a thumbnail list. By adding and recording metadata together with P2 content files, data can be efficiently managed, searched and edited.
When using a software keyboard or USB keyboard optionaltext data can be entered easily. It can simultaneously display player-side source material thumbnails or a preview screen on the left side, a recorder-side timeline preview screen on the right side, and the timeline at the bottom. This allows smooth, intuitive operation for users familiar with nonlinear editors and users accustomed to conventional DVCPRO laptop editors. V fade between events can be set only for audio. Insert and Overwrite editing mode: Inserting an event on the current timeline and overwriting the current timeline with an event modes are available.
Choosing a clip to be edited and overwritten like a VTR is possible. It avoids rendering edit copy and allows a quick correction. It lets you set IN and OUT points on the player-side preview screen by controlling an external VTR connected via an RSA interface, and register or capture digitization and clip creation video footage directly onto the editing timeline. This allows quick P2HD production from tape sources in a linear-like fashion.
From the video track and four channels audio track, a desired track can be selected and edited independently. Voiceovers for inserting a narration using a microphone is also possible. By using the audio fader, the audio level of a desired segment can be adjusted. Playlists can be saved to a P2 card, an external hard disk drive, or an FTP server.
In addition, by using the playlist export function, you can export playlists along with their associated clips including overlapping portions.
They can then be converted directly into editing sequence timelines, for post-processing such as adding effects and others, by using a nonlinear editing system that supports the playlist export function. Playlists can be saved as the files and reused. The editcopy function can also write out the result of playlistas a separate clip. This automatically detects the video format and codec for each video clip to playback and output.
AJ-HPM | P2HD Series | Broadcast and Professional AV
For slow-motion and double-speed playback. When you press the Play key, playback resumes at the bookmarked position. The bookmark memory is reset when the amnual is turned off.
This convenient function plays back one video clip with a one-touch operation. For presentations and demonstrations, use the AJ-HPM for repeated playback of a selected clip or multiple but same format clips. Playback is seamless, with no need for rewinding or cueing. There is no wear or image deterioration even after extended, continuous playback.
A wj-hpm110 file containing up to five groups of settings can be saved or loaded. You can assign frequently used menu items to the four PF keys, then select them instantly with the touch of a finger.
Audio can be monitored up to 10x normal speed. During up-conversion recording, the post-conversion waveform is displayed. Example of a waveform display. During playback, the time remaining until the end of the clip is displayed by the CTL counter.
Files can be uploaded or downloaded easily by using thumbnails. You can view thumbnails and metadata from a PC. It is also possible to enter authentication information ID and password for network access.
Some web pages may not be displayed properly due to content. Download functions on web pages cannot be used. Video clips on web pages or linked video files cannot be played.
This enables high-speed backup copying and data restoration at up to about 4x normal speed using an eSATA hard-disk drive. The maximum data transfer speed of the USB 2. If the data reading speed decreases temporarily due to vibration or when using a low-speed hard disk, it is possible to output only audio for continuous playback.
Source materials on a hard disk can also be used in playlist editing, just like source materials on a P2 card. By copying P2HD clips into lowrate AVCHD files, it is possible to perform transfer clips to a server at high speed or perform offline editing at high speed.
The AVC-Intra mode supports recording and playback of four channels of 24 bit high-quality digital audio with a sampling rate of 48 kHz. SDI embedded audio is also supported. For playback, equipment or software compatible with 24 bit audio is required. With its rugged casing and magnesium die-cast frame, the AJ-HPM is tough enough for go-anywhere field production.
The rear connector section is protected by a cover.
