*Requires appropriate network connection and adapter

Graphic & Titling Solutions for a Single Camera Operator

Designed for enhanced single-camera production, the GY-HM250U offers lower-third and full-screen titling solutions for recorded or streamed HD video output without an external CG or production switcher. Lower-third graphic overlays are generated and controlled using a browser-equipped device such as a tablet or smartphone. JVC's software utility lets customers upload logos or icons to be displayed in the lower-third of the recorded video. The camera also comes with several pre-installed color schemes and the ability to add your own text bar designs also exists. The new GY-HM250 is perfect for streaming broadcast news, weddings, school, family and church events, or literally any occasion you want to share live!

Integrated 12x Ultra HD Lens, 1/2.3-inch CMOS Sensor

Ultra high quality imagery begins with a precision 12x F1.2-3.5 optical zoom lens (35mm equivalent: 29.6-355mm). JVC's 4K CMOS sensor with 12.4M pixels delivers high sensitivity and excellent performance over a wide range of lighting conditions. Details are crisp and accurate throughout the entire image plane. When shooting in the HD mode, Dynamic Zoom combines optical zoom and pixel mapping to create seamless and lossless 24x zoom. This allows the camera to have a long zoom range while retaining its small form factor. Shooters will also appreciate the convenient ND filter wheel: 0, 1/4th and 1/16th positions.








 
 
 
 
 
 
 

4K Ultra HD Recording at 150Mbps and Live Output

Working with 4K has never been easier! Insert an SDHC or SDXC (UHS-I Speed class3) memory card and record hours of 4K Ultra HD (3840 x 2160) material. Recordings are made using the Quicktime (.MOV) file format and are compatible with many popular editing systems. Connect a 4K Ultra HD monitor with a single HDMI cable, and view the camera's live 4K signal. You can also play back recorded files directly from the camera. The camera also downconverts UHD signals to standard HD for output through the built-in HDMI connector.








 
 
 
 
 
 
 

4:2:2 Full HD recording at 50Mbps

The camera records 4:2:2 HD signals up to 60p at 50Mbps making it an ideal camera for general HD production work. 50Mbps files are stored in the Quicktime (.MOV) format for easy editing. Conventional AVCHD (4:2:0) recording is also possible, providing wide editing compatibility in an array of standard HD and SD formats.

Dual SDHC/SDXC Card Slots

Dual SDHC/SDXC card slots make this camera a truly versatile camcorder, offering such benefits as simultaneous recording and relay recording. In relay recording mode, you can shoot the event continuously over multiple cards—when one card is full, the camcorder switches automatically and seamlessly to the other card.

 

Clip Continuous Recording

In normal recording, when the recording stops, the image, audio, and accompanying data from the start until the end of the recording are recorded as one "clip" on the SD card. This mode allows you to consolidate several rounds of "startstop recording" into one clip.

For example, in normal recording three clips are generated as Recording 1, Recording 2, and Recording 3. However, recording in this mode the camera generates only one clip.

Web Friendly (Proxy) file formats

Lower resolution H.264 files (480x270p and 960x540p) may be recorded simultaneously with full HD files. These files are significantly smaller than HD files, and thus are very suitable for immediate posting to the web. A file recorded in the 960 x 540 mode is approximately 1/10th the size of a full HD file recorded at 35 Mbps, and therefore takes a fraction of the time to post. The smaller files may be quickly imported to an iPad for easy editing using iMovie or Pinnacle Studio. Transporting video to the web or back to the studio has never been faster.

S.L.I.M. Studio Camera System Design Concept

  • Simple design — addresses multiple levels of video operation and control.
  • Low Cost — a fraction versus traditional systems with full functionality.
  • IP Control — uses flexible and ubiquitous IP wired or wireless infrastructure
  • Multiple camera control — controls up to 100 cameras with a single RM-LP100U (tally control up to 5).


The SLIM system design is based on the RM-LP100U Remote Camera Control's latest firmware which enables painting and shading of our IP-capable camcorders, as well as simultaneously providing full control of our KY-PZ100 PTZ cameras! No other system offering incorporates a line-up of studio camcorder configurations providing the depth and diversity to meet the needs of professional applications from Education and House of Worship to Corporate, Industrial and Broadcast.
