Many kind of professional video cameras exist, and some of the most attractive are the compact cameras. These cameras have nearly all the advantages of bigger models, but with a smaller weight and size. This means that, besides being used in professional recordings, they are excellent for freelance journalists, sports, education, recording events, corporate videos and much more.
Panasonic announced the new AJ-PX270, the first P2HD handheld camcorder that incorporates AVC-ULTRA recording. This new camera combines high image quality with wireless Wi-Fi, 4G or LTE connectivity.
The PX270 provides new features that were previously only found in bigger camcorders (like the PX5000 from the same manufacturer). It also features a new capture device with three 1/3-type MOS sensors, with an excellent image quality even in low light.
There are already similar cameras from other manufacturers. The PX270 comes equipped with the new AVC-ULTRA codecs, with a wide range of recording modes: for high quality recording, you can select the AVC-Intra100 format, plus the optional AVC-Intra200 (which will be available soon).
Moreover, when file size is critical, the camera offers various AVC-LongG, including modes at 50, 25 or 12 Mbps. LongG50 and LongG25 offer a 4:2:2 quality and 10 bits in a small file size, saving storage space and reducing transfer time, while maintaining excellent quality.
Considering the need to exchange files at high speed, the PX270 allows proxy video recording at the same time of the high quality recording, making stream faster and easier. This proxy quality ranges from 800 Kbps to 6 Mbps, with full HD resolution in the latter case.
As Jaume Miró, Product Manager of Panasonic, said:
The flexibility and scalability of the AVC-ULTRA recording allows us to offer 10-bit and 4:2:2 at just 25 Mbps, which is a real achievement, allowing the users to stream HD video with the same bandwidth that until now has been used to stream standard definition video. This allows users to use microP2 or SD cards, and even make simultaneous recordings. The recording option is a 200 Mbps over the flexibility of the test camera, allowing for excellent quality pictures.
In addition to these options, the PX270 has a new compact lens with a 22x optical zoom, with levels ranging from 28 mm to 616 mm (equivalent to 35mm). The three manual rings (zoom, focus and iris) offer a manual control similar to an interchangeable lens system but without changing the lens.
Another distinctive feature of this new Panasonic camera is its connectivity. Network features are included as standard, although not all will be available from the start. You can send files via FTP or live via streaming transmission.
Initially, the PX270 can connect to a Wi-Fi network via an optional USB dongle or to a wired LAN network, and it is also compatible with devices that upload files to the internet. Adapters to use 3G/4G and LTE networks will also be available. Through these network connections, users can send content from the same place of the recording, both proxy and high quality, whether in the form of files or live streaming. This reduces the time between capture and broadcast of content and decreases the hassle of direct connections.
The Panasonic PX270 microP2 has two card slots, offering simultaneous recording, dual recording in two different qualities, or continuous recording in one of the two cards. Conventional SD cards for recording at 50Mbps or lower may also be used. Similarly, the camera has a P2 card slot.
Besides the 1080/50i format, the PX270 supports 1080/50p, 1080/25p, 1080/24p, 720p and standard definition, with their equivalents in 60 Hz. 1080/50p recording, available for the first time on a P2 handheld camera, can be performed in the AVC-Intra100 and AVC-Long G25 and G12 modes. It is also possible to create slow-motion effects.
