Date A Live Mf 720p Vs 1080i
Саня Гончаров
In the years since Olympus and Panasonic jointly announced the Micro Four Thirds standard there have been eight models launched to date, seven of which share the same 12MP sensor. The only exception was the GH1 which, despite its 12MP output actually featured a 14MP sensor. The sensor was slightly larger than the format's imaging circle, which allowed it to deliver images in different aspect ratios while retaining the same image diagonal. And now the GH2 follows the same pattern, shooting 16MP images using its brand-new, similarly over-sized 18MP sensor.
This sensor is capable of much greater readout speed (120Hz) than its predecessor, bringing a host of benefits. Videographers will see an improvement in the quality of the highest quality output - the 1080i output is derived from 60p or 50p capture, rather than doubled-up from 24p or 25p on the GH1. The faster readout also means the AF system can more frequently check the accuracy of its focus, which promises faster autofocus (on lenses that can respond quickly enough). Finally, the faster readout means the live view is updated 60 times a second (rather than 24fps displayed at 60hz), giving a smoother viewing experience with less tearing.
The newscasts were replayed on one of channel 7's digital subchannels, another which also carried local weather and news channel. WABC-TV's website had a link for live streaming video of "Channel 7 Eyewitness News NOW", which offered live local and national weather updated from AccuWeather alongside local news. The format of "Eyewitness News NOW" is similar to the defunct NBC Weather Plus. On February 24, 2011, AccuWeather and ABC both replaced ENN as well as similar news channels on WABC-TV's sister stations, KABC-TV in Los Angeles and WLS-TV in Chicago, replacing them in all three cities with a standard definition, letterboxed simulcast of the Live Well Network, and then on April 15, 2015, these stations were replaced by Laff.
The DMC-GF2 can record 1080i HD 1920 x 1280 movies at 60 fps (interpolated from 30 fps) or 720p at 1280 x 720 at 60fps in the AVCHD Lite (MPEG-4/H.264) format. In addition it can also record Motion JPEG movies at 320 x 240, 640 x 480, 848 x 480 and 1280 x 720, all at 30fps, useful as this format can currently be shared more easily. AVCHD features almost double the recording time in HD quality compared with Motion JPEG, but software support is still a bit thin on the ground. Panasonic describe it as the best mode for playing back on a HD TV direct from the camera, and Motion JPEG best for email and playing on a computer. Stereo sound is now recorded during video capture, helped by the wind cut function which blocks out most of the noise from background wind. You can't fit an optional external stereo microphone which is a little disappointing. The HDMI port allows you to connect the GF2 to a high-def TV set, but only if you purchase the optional HDMI mini-cable.
Both HD models feature professional 3G-SDI connections that are multi-rate and support SD-SDI, HD-SDI and 3G-SDI video formats while the Ultra HD model features 12G-SDI for HD-SDI and Ultra HD video formats That means you can choose from a model that lets you work with any professional camera or deck in all formats ranging from NTSC/PAL up to 720p, 1080i, 1080p and 2160p up to 60 frames per second. Check the tech specs for the model with the formats you need.
What was missing from the G1, though, was the ability to shoot video, a void that has since been filled by several video-equipped SLRs. Now, with the Lumix GH1, Panasonic responds to the SLR video world with a bang, delivering a camera with the manual control and autofocus ability you'd expect from a high-def camcorder, sadly lacking in video-equipped SLRs to date. The 12.1-megapixel GH1 is priced at $1499.99, a hefty chunk of change in this economy, but that hasn't stopped fans from enthusiastically buying snapping up the first few production models too quickly for Panasonic to keep up with demand. In the following review, we'll explore the pros and cons of this groundbreaking camera, with the experts from our sister site CamcorderInfo.com providing an authoritative comparison not only between the GH1 and two SLRs, but also weighing it against a first-rate high-def camcorder.
A single proprietary port is used for both USB and standard-def AV output. The video out aspect ratio when using the AV cable can be set to 16:9 widescreen or the standard 4:3 screen size. HDMI connections will ordinarily be set automatically, but it is possible to specify 1080i, 720p or 480p output if necessary. The camera is also outfitted with VIERA link, which allows remote control operation when using compatible Panasonic equipment (a nice capability for running slide shows from the sofa).
Sony's "WF-Series" Grand Wega TVs deliver big-screen excitement in a sleek, low-profile package. From the front, the 60" KDF-60WF655 looks more like a plasma TV than a rear-projection model! An updated design for the projection "light engine" makes this space-efficient cabinet possible.
DRC Palette: The DRC Palette allows you to customize the level of detail (Reality) and smoothness (Clarity) for up to three input sources. For example, you can create one Custom setting to optimize your cable input and another for your DVD player's picture. Note:This feature is not available for 480p, 720p, or 1080i sources.
BN Smoother: To reduce noise caused by the digital video encoding and decoding process, you can activate the BN Smoother feature. It is especially effective for watching a DVD or digital TV picture. You can select High, Medium, Low, or Off. Note: This feature is not available for 480p, 720p, or 1080i sources, or when using Twin View, Freeze, or Memory Stick.
