• 22x Panasonic Lens — Zooming in on New Levels of Image Expression
• High-Sensitivity, Low-Noise U.L.T. Image Sensor
• The High-Quality DSP Matches Image Processing and Quality to match Each Shooting Situation
• Rapid Response with Agile Shooting Assist Functions
• Exclusive P2HD High Image Quality: 10 bit, 4:2:2, AVC-Intra 100 Codec
The high-performance AG-HPX255/HPX250 P2 handheld camera recorders fill out the P2HD Series by incorporating the newest technologies throughout — in the lens, camera and recorder sections. The newly developed 22x zoom lens covers a wide shooting range, from wide-angle to telephoto, and features three manual rings for precise control. Imaging is optimized by the high-sensitivity, low-noise 1/3-type 2.2-megapixel U.L.T. (Ultra Luminance Technology) 3MOS image sensors. And the AG-HPX250/HPX255 are the first handheld models to support AVC-Intra codecs. This combination produces a level of performance that rivals many full-size shoulder-type camera recorders, and adds the high-quality acquisition of Full-HD (1920 x 1080) in 10 bit, 4:2:2 full sampling. Image expression is also boosted by the Variable Frame Rate (VFR) function, and system expansion for broadcasting and other production applications is provided by multi-camera synchronizing. The stylish design of the AG-HPX250/HPX255 adds further to both mobility and operating ease, and opens a new stage for news gathering and image acquisition. In addition to these specifications, the AG-HPX255 is fully prepared for broadcast use, including camera remote capabilities when combined with the optional AG-EC4G Extension Control Unit.
The high-performance zoom lens was developed specifically for professional HD video production. While inheriting the wide-angle capabilities of the DVX and HVX Series, it adds the same level of operating ease as you&d expect from an interchangeable lens model for broadcasting and other professional uses. Combining 18 lens elements in 12 groups, this advanced lens unit further adds a UHR (Ultra High Refractive) glass element, a low dispersion element and aspherical lenses. This newest optical technology can provide high resolution. In addition, it is combined with a unique Panasonic digital signal processing technology called Chromatic Aberration Compensation (CAC) to minimize color bleeding in the surrounding image and achieve rich expression with finely rendered nuances and excellent shading. Zooming from 28mm to 616mm (35mm equivalent), this 22x zoom lens covers a wide field of view, from wide-angle to telephoto, without a conversion lens.
The lens unit is provided with three rings — a mechanical (cam-driven) zoom ring, a focus ring, and an iris ring. You can operate them manually almost like an interchangeable lens including rugged operation of zoom ring.
• Hand-shake correction with the Optical Image Stabilizer (OIS).
• Digital Zoom function.* It can be assigned to an user button and close up to 2x, 5x, and 10x. In combination with the optical zoom, this function provides a telephoto capability up to 220x.
• Four-position (OFF, 1/4 ND, 1/16 ND, 1/64 ND) optical neutral density filter wheel.
* The digital zoom cannot be used while operating the Dynamic Range Stretch (DRS) or Scan Reverse functions. If either function is operated while digital zooming, the zoom will be automatically turned off. Also, Flash Band Compensation (FBC) will not operate while digital zooming.
The AG-HPX255/HPX250 feature the Ultra Luminance Technology (U.L.T.) 1/3-type 2.2-megapixel 3MOS image sensor that is incorporated in our shoulder-type P2HD camera recorders. This advanced image sensor is set to maximize the performance of the lens and signal processing circuit under standard shooting conditions. Progressive Advanced Processing (PAP) technology, which is driven by 3D adaptive processing, has also been further refined to enable high-sensitivity F10*, low-noise shooting in dimly lit places.
*AG-HPX255/HPX250 sensitivity is selectable, F10 is PAP Filter Type1 and F7 is PAP Filter Type2 in 59.94Hz mode. In 50Hz mode, F11 is PAP Filter Type1 and F8 is PAP Filter Type2. The default setting is PAP Filter Type2.
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-HPX255/HPX250 are equipped with highly accurate flash band detection and compensation software. 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.
The AG-HPX255/HPX250 incorporate a high-performance 20 bit DSP that handles image rendering processes such as gamma and various detail enhancement functions with exceptional precision.
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 DRS function does not operate in 1080/24p, 1080/25p or 1080/30p mode.
Drawing on technologies developed for the VariCam, Panasonic has equipped the AG-HPX255/HPX250 with advanced gamma functions that address seven different shooting scenarios, including two Cine-Like Gammas.
• Variable shutter speed from 1/6 to 1/2000 sec. plus Synchro Scan function.
• Matrix setting including a Cine-Like mode.
• Adjustable H detail level, V detail level, detail coring and skin tone detail.

These are the first handheld camera recorders to support the AVC-Intra codecs of the P2HD Series for HD recording of broadcast and movie images. Featuring a high compression ratio based on the new MPEG-4 AVC/ H.264 moving picture compression technology, this advanced system maintains intra-frame compression to provide both high image quality and excellent editing performance. It offers recording and playback of both AVC-Intra 100 and AVC-Intra 50 modes, and also supports DVCPRO HD recording and playback.
•AVC-Intra 100: 1920 x 1080,* 10 bit, 4:2:2
High-quality images with full-pixel HD and full sampling are recorded at the same bit rate as DVCPRO HD, bringing agile mobility to high-end production.
•AVC-Intra 50: 1440 x 1080,* 10 bit, 4:2:0
Image quality is the same level as DVCPRO HD, but with the SD (DVCPRO 50) bit rate. You get twice the recording time of DVCPRO HD, and about half the required data transmission time.
* These figures are for 1080i/p mode. The AG-HPX255/HPX250 also supports 720p mode.
• Native recording modes: In addition to 1080/59.94i with the AVC-Intra codec, native recording is supported at 1080/23.98p or 1080/29.97p and 1080/25p. In 720p, native recording is possible for both DVCPRO HD and AVC-Intra, making it possible to extend recording time by 2 to 2.5 times in comparison with pull-down recording.
* Camera through output and playback image output are pulled-down 59.94 (50) frames.
• Pulldown record mode: This VariCam-compatible mode records*1 with the DVCPRO HD codec. A 2:3 pulldown is applied to 23.98p, and a 2:2 pulldown is applied to 29.97p, to record 1080/59.94i or 720/59.94p and 1080/25p over 50i or 720/25p over 50p. The 23.98pA (2:3:3:2 advanced pulldown) mode is also supported, allowing editing on applicable nonlinear systems with little image degradation.
• 59.94Hz/50Hz selector: Supports worldwide HD/SD production.
• SD image acquisition: The DVCPRO 50/DVCPRO/DV multi-codec enables 480/576 image acquisition, with aspect ratio conversion. Select from Side Crop, Letter Box and Squeeze modes.
*1: Not compatible with the AVC-Intra codecs.
The AG-HPX255/HPX250 can record high quality/16 bit digital audio on all four channels. You can freely select the audio source for each channel, choosing from built-in mic, external mic and line-in. Level volume is also supported on all four channels.
In addition to allowing continuous recording onto two P2 cards, this system offers the following functions.
• Card select: The recording slot can be switched in Standby mode.
• Hot-swap recording: The card in the standby slot can be exchanged while the other card is being recorded on.
The P2 card was originally developed for broadcast use. In addition to its large 64 GB* capacity, it strongly resists impacts, vibration and temperature changes, and withstands repeated recording and initialization cycles for extended recording use. The card connector section is designed specifically for professional use, resulting in extremely high durability for insertion and removal. The P2 card and P2HD Series are widely used in broadcast and movie production studios and have a proven track record for reliability, durability and easy operation.
*Total card capacity includes space for data management such as system data; therefore, the actual usable area is less than the capacity indicated on the card.
File-based recording onto memory cards enables high-speed starts, recording starts with no need for cueing, and protection against accidental data overwriting. The recorded data is organized into MXF files. The files can be transferred to a nonlinear editor or over a network without the need for digitizing.*
*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. See "Notes Regarding the Handling of P2 Files Using a PC".
AG-HPX255/HPX250 Recording Format & Recording Time
*1: Native modes record only the effective frames.
*2: When you select 24 FRAME/30 FRAME in VFR mode in DVCPRO HD 59.94p mode.
*3: When you select 25 FRAME in VFR mode in DVCPRO HD 50p mode.
The Variable Frame Rate (VFR) function was inherited from the Panasonic VariCam, which is widely used for producing movies, TV series, and TV commercials. It creates a wide range of film-camera-like images, such as overcranking for slow-motion and undercranking for quick-motion effects.
Image Modes and Variable Frame Rates
• Normal cinematic shooting (at 24 fps, 25 fps or 30 fps) refers to the same rate as used in film cameras. The AG-HPX255/HPX250 can record in 24 fps. Note that 25 fps and 30 fps are the standard frame rates used in the production of TV commercials, music clips and video media.
• Overcranking (higher-speed shooting) produces a slow-motion effect. This is especially effective for high-action scenes like car chases or crashes, or to create a dramatic impact in a scene. For example, when a scene is shot at 48 fps and played at 24 fps, a slow-motion effect of 1/2x is attained.
• Undercranking (lower-speed shooting) gives you a quick-motion effect. This technique can be combined with a warp-speed effect to give special emphasis to flowing water, fast-moving clouds, etc. For example, when a scene is shot at 12 fps and played at 24 fps, a quick-motion effect of 2x is attained.
Recorded clips are automatically allocated a thumbnail image and metadata. This lets you display the thumbnail images on the LCD monitor, delete clips, and confirm or edit metadata (using the built-in Software Keyboard function).
• Last clip delete: The clip that was most recently recorded is deleted with a single touch.
• Rec check: The beginning and ending of the clip that was most recently recorded are checked with a single touch.
• Shot marker: Clips can be marked during or after recording. When mounted to a PC,*2 the user can display only the marked clips if desired.
• Text memo: This lets you post a memo on any scene of any clip, up to 100 memos in all, similar to a sticky note.
*1: Shot marker and text memo cannot be used in loop rec, interval rec, or one-shot rec.
*2: When using P2 viewer, a Windows PC viewing application that can be downloaded free of charge by P2 users. For details, see "P2HD series".
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.
• Loop rec: This repeatedly re-records a particular recurring time slot, always maintaining a recording of the most recent period.
• 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 the shot you want 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.
• Time stamp: The date and time can be stamped onto recorded images. Commonly used for evidential images.
* These functions cannot be used during Variable Frame Rate recording.
The optional Focus FS-P250 Proxy Recorder is compatible with the AG-HPX255/ HPX250 camera recorders. The Focus FS-P250 records proxy files onto SD/SDHC memory cards in parallel with the AVC-Intra or DVCPRO format files recorded onto the P2 cards in the camera recorder.*2 The proxy files are compatible with P2 file format and are linked to the P2 footage via filename, ID and metadata. This allows the proxy files to be easily used for offline editing applications; the editor only needs to replace the proxy data with P2 data before rendering the final video production.*3 The Focus FS-P250 supports high quality video (Quick Time/ H.264) and audio formats (see chart below " FS-P250 Recording Format ") at a low bit rate. The Focus FS-P250 high quality proxy files can be used for breaking news and other scenarios that would benefit from proxy workflows. Moreover, the Focus FS-P250 streamlines production workflow by allowing the editor to review the content details during offline editing.
