A Micro Four Thirds mount camera with CCD sensors

Which means no jello in videos: No joke: SVS-Vistek makes a MFT mount camera with global shutter! | 43 Rumors.

As I understand them, CCDs read/write a frame at a time, unlike the line at a time used in lower powered CMOS sensors. Both can take great photos, but when it comes to video, CMOS results in the “jello effect” seen in handheld smart phone and even high end dSLR cameras using CMOS sensors. HOWEVER, I do not know from the story whether these sensors and cameras would be used for shooting video.

And you may be surprised at who designs and manufactures the image sensors.

Is a 10-bit video codec always way better than an 8-bit codec?

It depends:

“As long as you have the right 8-bit, youre fine." DSLRs like the 5D Mark III have 14-bit sensors, but for video capture, they’re converted down to 8-bit. Its this 8-bit “secret sauce” that the experienced engineers are able to pull off.  “If the engineers are getting the right 8-bit in that final codec, its visibly lossless,”

It also depends on the lighting in the scene. If the scene has a high dynamic range, more bits are better. If the scene’s dynamic range is shallow, fewer bits are needed to capture the full range. And, like the above, it also depends on how the codec itself works to capture in 14-bits but mix down to 8-bits.

New 3D-capable Set Top Boxes Coming from ZTE

Says the new STBs will support Internet content:

ZTE Corp. 763, China’s second-largest maker of telephone equipment, plans to release digital set-top boxes for 3D television services that will run Google Inc. GOOG’s Android operating system.

Which is why I think 3D is going to occur via the Internet more than the traditional broadcast pipes, particularly while 3D is a growing niche.

Video: Pvt. Hugh McLaughlin (1835-1906)

A mini documentary I produced today. Was invited to record an honorary ceremony and headstone dedication for Pvt. Hugh McLaughlin (b.1835-d.1906). He was buried in Greenwood Memorial Terrace in 1906 but his grave was unmarked and his Civil War service was unknown. Local Civil War history enthusiasts, re-enactors, and others took part in a graveside ceremony to honor Hugh McLaughlin. In attendance were a granddaughter, great granddaughter, great great granddaughter and other extended family members. Photographed using a Canon XH A1 and AT-835b shotgun directional mic. I also shot some 3D any may edit that at a later date.

Local news story on the ceremony is here and background on how the grave was discovered and the many people who researched the genealogy, the history and worked to obtain a new headstone.
