Fujinon High-Performance 17x Zoom Lens
The AG-HPX370 series comes equipped with a Fujinon 1/3-inch 17x zoom lens. Optimized for use with the AG-HPX370 series, this high-performance HD lens incorporates advanced broadcast lens technologies to achieve a compact size, light weight, F1.6 at 4.5 mm f-value at the wide end, and excellent zoom response. The zoom is comfortable to grip and use. Also, quick zoom and auto cruising zoom functions can be allocated to the VTR and RET switches.

Chromatic Aberration Compensation (CAC)
This exclusive technology sets up a conversation between lens and camera which allows for a highly sophisticated algorithm to be deployed that will automatically compensate the registration error that is caused mainly by lens chromatic aberration, and minimize the circumjacent blur.

Simulation Showing the CAC (Chromatic Aberration Compensation) Effect

Dynamic Range Stretch (DRS)
In scenes with mixed contrast, such as when panning from indoors to outdoors, the DRS function automatically suppresses blocked shadows and blown highlights. A gamma curve and knee slope are estimated to match the contrast of each pixel, and applied in real time. When dark, bright, and intermediate shades are all contained in the same scene, this produces excellent gradation for each shade and minimizes blocked shadows and blown highlights. The images that result are enhanced by a visually wide dynamic range.
*The DRS function does not operate in 1080/25p, 1080/24p or 1080/30p mode.

Flash Band Compensation
In contrast with the CCD image sensor, which accumulates still images of single frames that are exposed with identical timing, the MOS image sensor uses a rolling shutter system that sequentially scans each line of pixels. This lowers power consumption and enables high-speed drive, but because the exposure timing differs for each line, when an external flash is used, it tends to produce images where the brightness is divided between the top and bottom of the image. This is called the flash band effect. The AG-HPX370 series is equipped with highly accurate flash band detection and compensation software on the camera’s signal processing LSI. By generating pairs of frames containing flash bands, and frames in which a flash extends from the previous frame to the entire screen, and then using the compensation process to adjust the level, the flash band effect of MOS-based imagers is eliminated.

3-Position Gain Selector / 24dB Gain-Up Function
There is a 3-position gain selector, with L, M and H settings. To each setting you can assign a gain value from -3 dB to 12 dB, in 3 dB steps. There is also a USER button - just give it a quick touch to instantly boost the gain by 24 dB.

Newly Developed 20 bit Digital Signal Processor
The AG-HPX370 series incorporates a high-performance 20 bit DSP that handles image rendering processes such as gamma and various detail enhancement functions with exceptional precision. Consuming less power than conventional processors, the new DSP contributes to the AG-HPX370 series outstanding environmental performance.

Scene File Dial
Set this dial for an instant set of shooting conditions. Six preset files are provided, and you can change any of the six file names and their settings as desired. You can also store and load the settings to and from an SD card.

• Normal cinematic shooting (at 24 fps, 25 fps or 30 fps) refers to the same rate as used in film cameras. The AG-HPX370 series can record in 1080/24p (over 60i) or 480/24p (over 60i) mode, as well as 720/24p mode. 25 fps or 30 fps is the standard frame rates used in the production of TV commercials, music clips and video software. The AG-HPX370 series can also record in 1080/25p (over 50i), 1080/30p (over 60i), 576/25p (over 50i) or 480/30p (over 60i) mode, as well as 720/25p and 720/30p mode.

• Higher-speed shooting (at over 25 fps*) produces slow-motion effects. This is especially effective for high-action scenes like car chases or crashes, or to create a dramatic impact in a scene.
*When the standard speed is 24 fps in 59.94 Hz mode. For a standard speed of 25 fps in 50Hz mode, anything over 26 fps will be overcranked.

• Lower-speed shooting (at under 22 fps*) lets you attain a fast-motion effect. This technique can be combined with a warp-speed effect to give special emphasis to flowing water, fast-moving clouds, etc.
*When the standard speed is 24 fps in 59.94 Hz mode. For a standard speed of 25 fps in 50 Hz mode, anything under 24 fps will be undercranked.

Native and Over-50p/60p Modes
• 720p Native Mode
In Native mode, the AG-HPX370 series records images at the frame rate set in the camera. For example in 24 pN mode, it only records 24 frames instead of the normal 60 frames*. Using the AG-HPX370 series to play back the recording at the normal rate, you can preview the speed effect right on the spot, without using a frame rate converter. Native mode also extends the recording time of a P2 card.
*In 25 pN mode in 50 Hz system mode, AG-HPX370 series records only 25 frames instead of the normal 50 frames
• 720p over 50p/60p Mode
This is a mode for recording 50p-converted or 60p-converted video. For example, in 24p mode, it records 60 frames by applying a 2:3 pulldown. The recording time is the same as in 1080i or 720p mode, but the unit can output a DVCPRO HD stream from the IEEE 1394 connector as it records.* This lets you produce a backup copy using a connected external P2 recorder such as AJ-HPM200 or AG-HPG20, DVCPRO HD recorder.
*Only when the recording format is DVCPRO HD. There is no output when the AVC-Intra codec is used.
*24p = 23.98p, 30p = 29.97p, 60p = 59.94p and 60i = 59.94i

1080/480 24p Advance Mode (in 59.94Hz mode)
The 1080 and 480 progressive recording systems convert recordings to 60i in 24p, 30p, or 24pA (Advance) mode. The 24p Advance mode uses 2:3:3:2 pulldown, which allows for an easy extraction to a 24p timeline and no quality loss in the process with compatible NLEs.*
*AVC-Intra recording is not possible.* For information on compatible nonlinear editing systems, visit"Nonlinear Compatibility Information." *24p = 23.98p, 30p = 29.97p, 60p = 59.94p and 60i = 59.94i

Scan Reverse Function for Use with Film Lenses
The AG-HPX370 series comes with scan reverse. This function cancels the image inversion that occurs when a Cinema lens adaptor is used.

AVC-Intra Codec
High-quality 1920 x 1080 pixel, 10 bit, 4:2:2 HD recording

Comes Equipped with AVC-Intra Codec
An AVC-Intra codec board is included as standard equipment.
It allows recording in either of two modes: AVC-Intra 100 for full-pixel HD (1920 x 1080 and 1280 x 720) images, or AVC-Intra 50 for low-bit-rate, low-cost operation. AVC-Intra is a new codec that further advances HD production. It complies with the MPEG-4 AVC/H.264 international standard based on advanced image compression technology, and offers both superb image quality and highly efficient compression. It uses an intra-frame compression system to bring important advantages to professional editing.
In the AG-HPX370 series, a new single-chip digital signal processor is integrated with the AVC-Intra codec circuit. This is another way the AG-HPX370 series reduced power consumption.

High-Image-Quality AVC-Intra 100 Mode
With the same bit rate as DVCPRO HD, this mode supports full 10 bit recordings with 1920 x 1080 pixels. It enables the AG-HPX370 series to capture master-quality video for high-end video production.

Low-Bit-Rate AVC-Intra 50 Mode
This mode delivers video quality very similar to DVCPRO HD, yet is able to do so at bit rates usually associated with standard definition (e.g., DVCPRO 50). AVC-Intra 50's lower bit rate doubles the recording time per P2 card over DVCPRO HD and lowers storage requirements for editing.

HD Multi-Format Capability, Including Native 24p
The AVC-Intra 100 and 50 codecs let you record in a choice of HD video formats: 1080/25p, 1080/50i, 1080/23.98p or 29.97p as well as 1080/59.94i. These HD formats bring extra flexibility to all of your production needs. The AG-HPX370 series also supports 720p recording for HD image production in a variety of formats, including 50p, 59.94p, 23.98p and 29.97p.

Selectable DVCPRO HD Recording
The AG-HPX370 series also supports the conventional DVCPRO HD codec. Because the AG-HPX370 series are designed to be used with the AG-HPX170 series/HVX200A series or a DVCPRO HD VTR, it adapts to a variety of system configurations.

48-kHz/16 bit, 4-Channel Digital Audio
The AG-HPX370 series can record full 48-kHz/16 bit digital audio on all four channels. You can freely select the audio source for each channel, choosing from mic-in, line-in and wireless receiver.

Sample Images of Intraframe Preduction
Left: Original image Center: Intra-frame predictive image Right: Difference image obtained from subtracting the intra-frame predictive image from the original image. This shows the high accuracy of intra prediction.

Intra-Frame (I-Frame Only) Compression Superiority
Motion-image compression can be divided roughly into two methods: I-Frame Only compression, which completes all processing within each frame, and Long GOP compression, which processes across multiple frames. AVC-Intra and DVCPRO HD use I-Frame Only compression, while HDV uses Long GOP compression.
The MPEG-4 AVC/H.264 standard encompasses both methods.
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 flash-filled press conferences, fast-action sports, and video with rapid move 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.

Twice the Compression Efficiency of MPEG-2
By selecting the most effective compression techniques from among those in compliance with the H.264 standard, AVC-Intra has doubled the compression ratio of MPEG-2, even with I-Frame Only compression. Its intraframe predictive and context-adaptive entropy coding are particularly effective methods for boosting compression efficiency.

Intraframe 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. Because the prediction accuracy is high, there’s minimal residual data, and thus high compression is achieved. This process is conducted within the frame, so prediction accuracy remains high even with fast-motion images.

Context-adaptive entropy coding
The entropy coding process used in MPEG-4 AVC/H.264 utilizes CAVLC (Context Adaptive VLC) and CABAC (Context Adaptive Binary Arithmetic Coding), both of which are context adaptive. 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.

P2 Recorder Section
The P2 recorder section offers reliable, large-capacity, high-speed memory card recording and a number of advanced functions.

The P2 Card: Reliable, Reusable and with Extended Recording Time
P2 cards feature a large capacity of up to 64 GB*¹, a compact size, and light weight. In addition to the semiconductor memory’s inherent resistance to impact, vibration and temperature change, the P2 card also offers outstanding reliability. Unlike tapes and discs, it has no rotating or physically contacting parts. It’s built to withstand repeated recording and initialization over many years of use. The P2 card connector is specifically designed to stand up to the repeated insertion and removal involved in professional use. The E Series*² (AJ-P2E016XG, AJ-P2E032XG, and AJ-P2E064XG) provides lower cost recording capability for those customers with budgetary concerns.
*1: Total card capacity includes space for data management such as system data; therefore, actual usable area is less than the capacity indicated on the card.
*2: When using the P2 card E Series, software updates are necessary for certain P2 devices. For details, visit "Support Desk"

Immediate Startup and Better Data Protection
When you press the Record button in standby mode, the AG-HPX370 series instantly finds a blank area on the P2 card and begins recording. It can begin recording immediately even when you’re using it to preview video. In normal use, there is no chance of accidentally overwriting a recording. Recordings will not be erased unless you intentionally delete a file or initialize the card.

Clip Thumbnail Function
The P2 HD camcorder automatically generates a thumbnail image for each clip. You can view thumbnails on the built-in color LCD monitor. Any of the clips can be accessed instantly. Thumbnail images can be paused, fast-forwarded, and reversed just like a tape, and unwanted cuts can be deleted by selecting and deleting the corresponding thumbnail image. You can also specify a number of clips for seamless playback* or on-air broadcasting from fields. And if a shooting opportunity should arise during playback, the P2 HD cam lets you start recording immediately with no cueing required and no risk of accidentally overwriting valuable data.
* Seamless playback is not possible between clips recorded in different formats.

New One-Clip Rec Mode
The One-Clip Rec mode is handy for recording a variety of events. Whereas normal Rec mode produces a clip for each Rec start/stop cut, One-Clip Rec mode records up to 99 consecutive cuts as a single clip, which greatly improves the nonlinear editing work that follows. A text memo is automatically attached when recording begins, making it easy to find desired cuts within the clip. For details, please visit "Support Desk".

Direct Upload to a PC*¹ or Nonlinear Editor
The AG-HPX370 series records the A/V data for each recording as a file on the P2 card, which eliminates the need for digitizing. The files can be used directly in a nonlinear editing system or transferred over a network or simply onto a Hard Disk Drive. The P2 card transfers data at a high speed up to 1.2 Gbps*² giving you faster, easier operation. The P2 card is convenient too - you can plug it directly into the card slot on certain laptops.
*1: PCs must be installed with the included P2 driver in order to mount P2 cards. For editing, PCs must be installed with P2-compatible editing software available from various companies. Read "Notes Regarding the Handling of P2 Files Using a PC".*2: 1.2Gbps is maximum transfer speed when using P2 card E series. Transfer speed is subject to be changed depended on system configuration.

Advanced Recording Functions Employing Two Card Slots
In addition to continuous, double-card recording, the AG-HPX370 series also enables some useful recording functions that are possible only with memory cards.
• Card selection: The recording slot can be changed (sequential switching). This lets you review, organize, edit and transmit just-recorded content. Content can also be organized while shooting, by switching cards for each scene category.
• Hot-swap rec: Thanks to the two card slots, you can hot-swap P2 cards for continuous non-stop recording. With multiple cards you can record for hours without interruption.
• Loop-rec*: The real benefit of loop recording can only be dramatized when you don’t know when the event is going to happen, you just know that it will. By allocating the open space on the cards the camera will continue to record over that area until the operator pushes the stop button, thereby assuring that the recording has been made, and the event captured.
• Pre-rec*: While in standby mode, you can continuously store, and subsequently record, up to 3 seconds in HD (7 seconds in SD). This will help you to get your shot every time.
• Interval rec*: This gives you automatic intermittent recording based on a set interval and recording time.
• One-shot rec*: This frame-shot recording function is useful for producing animations.
• Rec review: This lets you run a quick playback check of the 2 to 10 seconds that lead up to the end of the clip you have just recorded.
* These functions cannot be used for variable frame rate, native mode, and 1080/24p over 59.94i, 720/24p over 59.94p, 720/25p over 50p recording.* Pre-rec is not possible in loop-rec, interval-rec, or one-shot rec mode.

Text Memo (Bookmark) for Simple Editing
When recording or previewing a clip, press the Text Memo button at any of up to 100 locations and a text memo label, similar to a bookmark, is registered. Using only the AG-HPX370 series, you can create a new clip with data copied between text memo labels. Text information can also be written into each memo using the AG-HPX370 series or a PC with P2 Viewer installed. A shot mark, which allows convenient OK and NG marking, can also be added to each clip during or after recording.
*Text memo, shot mark can not be added in Loop-rec, Interval-rec, or One-shot rec mode.

SD/SDHC Card Slot
The AG-HPX370 series comes with an SD/SDHC card slot. You can create a metadata upload file (produced with P2 Viewer software or the Third Party software,) containing information such as clip name, the name of the camera operator, the recording location, and text memos on an SD/SDHC card, and load it as clip metadata. This information will be very useful when it comes to editing the project and quickly finding the right clip to place on the timeline. The SD card slot is also used to upload scene files, user files and firmware updates.

Proxy Data Recording (Option)
When the AJ-YAX800G proxy video encoder is installed, the AG-HPX370 series can record MPEG-4 proxy (low-resolution) data onto a P2 card and SD/SDHC card. This can be used for quick viewing of dailies with timecode, and its low bit rate provides easy transmission over wired and wireless networks.
*Proxy data cannot be recorded when recording with the variable frame rate in Native/Pull-down mode, or when Loop-rec, interval-rec, or one-shot rec is used. Proxy data refers to MPEG-4 low-resolution AV data in file form for moving images and audio, with timecode, metadata, and other management data included. The use of DCF Technologies is under license from Multi-Format, Inc.

16:9/4:3 Aspect Ratio Conversion
The 16:9/4:3 Conversion mode can be used with SD-recorded images or SD output down-converted from HD playback. You can select from three modes: side crop, letterbox, and squeeze.

Compatibility with Nonlinear Editing Systems
In developing P2 products, Panasonic has been working in collaboration with a number of strategic P2 Partners.
There are many nonlinear editing products in the market that already support P2. P2 native editing makes it possible for you to maintain high-quality video and a flexible editing workflow.*
* For information on compatible nonlinear editing systems, visit "Nonlinear Compatibility Information." For the operating requirements and other details of editing software, visit the website of the relevant software manufacturer.

Operation
The new design improves mobility and operating ease while supporting a variety of assist functions.

New Design for an enhanced Level of Mobility
The AG-HPX370 series innovative new form brings greater mobility, comfort and operating ease to the familiar shoulder-held shooting style. The body is small and weighs just 3.6 kg (7.9 lbs) with viewfinder. A large shoulder pad and low center of gravity combine to ensure outstanding stability on the shoulder. The low-profile design also provides an unobstructed view to the camera operator’s right.

Controls and Card Slots Grouped on One Side
All operation switches and volume controls are set on the left side of the camera. P2 card slots, which were set on the right side in previous models, have also been moved to the left side. Their logical horizontal arrangement makes it easy to insert and remove cards quickly.

Low Power Consumption - Only 19 W
By developing a new energy-efficient DSP and integrating the AVC-Intra codec circuitry with it, Panasonic significantly downsized the printed circuit board. This not only makes the AG-HPX370 series smaller and lighter, it also reduces power consumption. The new image sensor helps lower power consumption too. Together, these innovations reduce power use to only 19 W during recording. The lower battery consumption can mean greater mobility in the field.

Focus Assist Functions
Press the Focus Assist button and the center section of the screen expands in size, making it easier to determine if the focus is correct. Also, the Focus Bar* that visually indicates the focus level can be displayed on the screen.
