Firmware Hacks: Recording High Bitrates on Small Cameras

by Daniel Bruns | June 15th, 2010

Just a few short days ago, news came out that the firmware for the Panasonic Lumix GH1 got hacked. Now typically, you’d think that was a bad thing, and typically, you’d be right. However, in this case, that is far from the truth. Instead, the firmware hack for the GH1, made by Tester13, allows it to take MJPEG videos with a bitrate of up to 50 Mbps. That’s right; 50 Mbps. This is a higher bitrate than even the Canon 5D Mark II can take right now, with it’s average of 35 Mbps meaning cleaner footage with less artifacts. With the ability to shoot at 50 Mbps, video on the Panasonic Lumix can come out with almost no visible compression at all. The gradients in the footage look smooth and natural, and the detail is, for a lack of a better word, astounding. As an added bonus, since the GH1 scales and processes data by binning individual pixels rather than using line skipping, giving it a cleaner image than a 5D when downscaled from its 12 MP sensor. Also with this hack comes some groundbreaking workflow improvements. Using the 32 Mbit AVCHD mode with this hack, you can edit the native 24p footage natively on a Mac and PC in a fraction of the time.

All this comes at a small price however. First, the camera will often have card read/write errors due to the high bitrate and of course, fills up a CompactFlash card really fast. Also, playing this high bitrate footage will cause many computers to choke. Of course, as a firmware hack, there is at least a small potential that your camera’s hardware could be adversely affected by allowing it to do something it shouldn’t. Lastly,  the sensor size of the full frame 5D compared to the smaller APS-C makes for a greater chance for noise.

Nonetheless, hacks like these do effect one thing: they show camera companies how badly their users want these functions in their cameras. You sometimes have to wonder why they don’t just outright develop these same hacks into upgrades that their users can have. It would be a great chance to score some points with consumers that want to get the most out of their cameras and wouldn’t be of any harm to those who would never use the feature. Other cameras such as the Canon 1D Mark IV could also benefit from a small upgrade too. I mean can somebody tell me why Canon still hasn’t gotten rid of the auto gain control in the 7D and 1D too? Hopefully these companies will take a hint and start providing the relatively easy features that users want out of their cameras so that they can feel good about their purchases and feel good about staying loyal too.

Panasonic Point-and-Shoot to Record Video in AVCHD

by Daniel Bruns | June 8th, 2010

Just today, Panasonic tagged a price on to their recently-introduced LUMIX FX75. This tiny camera with a 24mm ultra-wide angle lens will be going for just $299.95. The newest offering from Panasonic will also include a 5x optical zoom and best of all, record video in the AVCHD Lite format instead of the conventional Motion JPEG format. This should be a huge sigh of relief to cinematographers looking to utilize the benefits of a photographic sensor while still being able to edit in a widely supported format. Of course, if you just got used to editing in the Motion JPEG format, the LUMIX also offers the option to record in Motion JPEG, WVGA (848×480) and VGA (640×480). The camera also takes pictures at 14.1-megapixels and has a 5x zoom to boot.  The LUMIX also has a full touch-screen for operating the autofocus feature on the camera. By pressing on the screen where your subject is, you can set and track a subject in your frame. At the same time, in playback mode, users can use the touch-screen to browse through their collections of photos much like a page in a book. The Panasonic LUMIX FX75 will be available for purchase in mid-July.

Panasonic Introduces the LUMIX DMC-ZR3 Featuring AVCHD Lite HD Video Recording Capability

by mhageman | January 26th, 2010

Panasonic-bkPanasonic today announced the introduction of the LUMIX DMC-ZR3, a fully-featured digital camera complete with AVCHD Lite High Defintion (HD) video recording capabilities, a25mm ultra-wide-angle Leica lens and a powerful 8x optical zoom – giving consumers a wide-range of shooting options, yet in a slim body that is small enough to fit in a pocket or small purse. New to the ZR-Series this year, Panasonic also introduces Intelligent Zoom, which extends the LUMIX ZR3’s zoom to an impressive 10x. Read the rest of this entry »

Making Videos with DSLR’s

by jburkhart | March 26th, 2009

5dmkiiDigital still cameras have had rudimentary video capabilities for some time. However recent advances in high end models such as the Panasonic Lumix DMC-GH1k, Nikon D90, and the Canon 5d mark II have made the idea of creating high-quality video content on a still camera a reality.

For the first time in it’s history Videomaker will review a still camera (Canon 5D mkII) in it’s pages, and we will add the Digital Single Lens Reflex (DSLR) as a new category of camcorder henceforth. As you would expect, the focus on the review will be on the video capabilities of the camera, with a brief overview of its still photo functions.

We will focus on using the DSLR in real world shooting conditions, in terms of capacity battery life, audio capabilities and other practical tests. The footage that we’ve seen so far is very impressive, but there are some real limitations to capturing video with DSLR’s at this stage.

In broad strokes, some of the advantages of the DSLR video format are:

  • Full Frame 35mm Sensors create a shallower Depth of Field
  • High quality and relatively inexpensive lenses
  • Integral “film look”

Some of the disadvantages are:

  • Limited record times
  • Poor audio capability
  • Limited video controls
  • Lens zoom and focus not designed for motion pictures, only stills

While still very much in their infancy, I expect that DSLR’s will make great strides in the near future in terms of video capabilities, and will be viable digital cinema cameras after a few versions.
