The HVR-A1U is a compact and lightweight handy-type camcorder, perfect for shooting environments that need mobility. Its size, combined using its long battery (up to 80 minutes of high-definition recording using the included battery), make it all to easy to have the shots you need, once you need them.

See large image HDV 1080i
The HDV 1080i specification features 1080 effective interlaced scanning lines and 1,440 horizontal pixels. Interlaced pictures, which happen to be common to TV broadcasts from the beginning, alternately display odd and also numbered lines between each screen refresh. The HVR-A1U can also record on the HDV 720p specification, which features 720 effective progressive scanning lines and 1,280 horizontal pixels. Progressive scanning fills both odd and even numbered lines with each refresh, providing a flicker-free picture.

Not yet ready for HD? The HVR-A1U can convert material from 1080i into 480i and output this digital video signal through its i.LINK interface or as analog signals through component, composite, or S-video connectors. When down-converting these signals, the aspect ratio displayed can be converted from 16:9 to 4:3, and display modes might be selected from squeeze, letterbox or edge crop.

1/3-inch Type, 2.97-megapixel CMOS sensor
The HVR-A1U incorporates one 1/3-inch type primary color CMOS (Complementary Metal Oxide Semiconductor) 2.97-megapixel sensor with a formatted to get a 4:3 aspect ratio. The advantage of the CMOS sensor over CCD is it's power to process a sizable volume of picture data at a very small size, which helps it be possible to get a camera this size to capture HD video. The trade off just for this sort of chip over CCD, however, is really a small reduction in picture uniformity and dynamic range.
Keep an eye fixed on audio levels for the LCD monitor
Audio
The HVR-A1U adopts the MPEG-2 compression format, which uses 8-bit digital component recording using a sampling rate of 4:2:0. The camera uses MPEG-1 Audio Layer II audio compression format, permitting two-channel recording which has a sampling frequency of 48 kHz/16-bit. It includes a built-in stereo microphone, as well as two XLR audio input connectors for use with professional-grade microphones or external audio sources. Each input level for CH1 and CH2 could be independently adjusted using two audio level dials on the camera body and viewed having an audio level meter on the LCD monitor.

Carl Zeiss Vario-Sonnar T* 10x optical zoom lens
The HVR-A1U is equipped which has a Carl Zeiss Vario-Sonnar T* high definition lens using a 10x zoom function. It has a similar optical coating as is used on all with the Carl Zeiss prime lenses, which produces sharp, high-contrast images with virtually no chromatic aberration.

In order to facilitate zoom control and recording operation during low-angle shooting, yet another zoom lever may be added on the camera body. There's also a zoom/focus ring located for the lens body that allows for fine adjustments in zoom position. Furthermore, the supplied wireless Remote Commander unit can be useful for external control.

Large, 16:9 widescreen color viewfinder and LCD monitor
View your subject from the built-in viewfinder, the swing-out LCD display, or both. The HVR-A1U includes a 0.44-inch type color LCD viewfinder and a 2.7-inch color LCD monitor, both in a 16:9 aspect ratio. You'll save battery time through the use of just one, nevertheless, you may desire to play one for adjusting focus and another for monitoring audio levels. When eschewing auto focus to the fine-tuning manual focus, you are able to double magnification on the center of the screen, rendering it better to confirm focus settings during manual focusing. Also, the camera's "peaking" function can offer sharp outlines about the monitor to aid with manual focus.

Electronic Super SteadyShot system
Sony's electronic Super SteadyShot System helps eliminate the slight hand jitter and vibration that's usually the bane of video production--especially during telephoto shots. It performs this by trimming off edges of the frame for the fly to counteract movement.
Tele Macro sees details on subjects coming from a distance
Tele Macro
It might seem like a contradiction in terms, nevertheless the Tele Macro function allows one to capture a macro image from your distance, which can be useful for shooting small moving objects. Additionally, this function puts your subject in proper focus while leaving the background out of focus.

The Hollywood look
The HVR-A1U has features that can make your videos look much more these were shot on film. Cinematone Gamma allows operators to quickly setup and load a gamma curve with similar contrast characteristics to your film gamma curve. The Cineframe feature allows movement being reproduced at 24 frames per second--the speed of film--as in opposition to video's 30 frames per second standard.

No new tape stock
The HVR-A1U is appropriate for conventional DV tape stock, but Sony recommends using DigitalMaster PHDVM-63DM tape, with its dual layer of magnetic material, which delivers higher RF output, lower noise, 95% fewer errors and 60% fewer dropouts compared to regular DV tape.
