Sony NXCAM HVR-NX5U

Published on October 20, 2010 by in cameras, NXCAM

Sony NXCAM

This is Sony’s first pro AVCHD camcorder.  In fact, I’ve just acquired one for my own use.  With all the craze about using DSLRs for video, they fall far too short for me for some of the work I do.  Covering an entire days worth of seminars for example.  This camera has to SDHC slots (or Memorystick Pro) and with two 32GB cards, over six hours of non stop footage is possible.  You can even switch cards while actually shooting,  allowing almost unlimited time.  Clips that span multiple cards can be rejoined in software.  An optional hard drive allows up to 11 hours of capacity.

The Sony “G” lens goes all the way from an approximate .6X wide angle, to a 20X zoom.  This camera adds an enhanced stabilization mode called “Super Steadyshot”.  I was able to get shots in this mode that almost looked as if I was using a Steadicam device, but in fact they were shot handheld.

This camera uses three 1/3″ CMOS sensors.  Sony also adds some special processing to enhance the video quality from these relatively small processors.  The results are very impressive, and get quite close to some of the big sensor pro cameras.  The shotgun mic seen here is actually included with the camera.  An improved model over the previous shotgun offered with its predecessors.  Audio quality with this mic is quite impressive.  The overall audio performance of the NX5 is greatly improved over previous models.  Lots of audio options too.  Assignable channels, internal stereo mic, phantom power, a limiter, and so on.

I’ve used Sony gear for years shooting event video, and video for business.  They are certainly not without their flaws.  These cameras do however shine brightly in critical areas.  The addition of this tape-less model is a welcome one.

Panasonic’s Large Sensor AG-AF100 Camcorder

Panasonic AG-AF100

I was tempted like so many to make the DLSR plunge for video production.  The shortcomings of such a rig just seem to outweigh the advantages.  I was only a matter of time before manufacturers combined the best of both worlds.  Panasonic’s upcoming AG-AF100 looks to be a major benchmark, as the second large sensor camcorder in the sub 10K range.  It looks to offer much more than the Sony VG10, but is quite a bit more expensive, at $5000 for the body sans lens.

The official Panasonic site is here, but a local dealer has a page with much more information, and it’s here.

Sony NEX-VG10 Review

Published on September 19, 2010 by in cameras
Sony NEX-VG10

Sony NEX-VG10

I just ran across this review of the new Sony NEX-VG10 camcorder.  While it resembles some of Sony’s other “Handycams”, it differs significantly in design.  It uses the same large CMOS sensor as the Sony NEX series still cameras.  This results in the sort of great depth of field images people are getting from DSLR’s while shooting video.  And like those cameras, the lens is interchangeable.  Unlike the various still cameras that shoot video, the design is much more suited to shooting video.  One of the most appealing aspects to me, is that it does not suffer from the arbitrary shot time limit of DSLRs.  Record time is only limited by media size and format.  A whopping three continuous hours can be recorded on a 32GB card at the highest quality setting!

I look forward to getting my hands on one to check it out.  For a $2000 list price, it seems like a pretty good deal to me.

Creating quick one shot Panoramas

Published on September 9, 2010 by in video

Click ..! Click..! Click..! Click..! Stitch… stitch…stitch..stitch. Aaarrrgh..! Well many of y’all might be aware of this process for creating panoramas, so I am not going to talk about that it here. This traditional process of making panoramas i.e. taking multiple images and stitching them involves lot of effort and time. While taking landscape panoramas might be relatively easy this way, making panoramas of a scene with lots of fast moving objects – the stitching can take hours to make it look seamless. And imagine the effort that would involve in a 360 degrees video – stitching frames seamlessly would be a nightmare…!

Panoramic photography has been a niche area in photography so far. I have often seen realtors shooting 360 panoramas of their properties and landscape panoramic photographers but not much in sports or people photography. With 360 degree cameras likes the Sony bloggie, Sony TX1 (~250 degrees panoramas), GoPano+ optics(complete 360 degress) etc the panoramaic photography scene seems to be catching up. Creating panoramas for live events, action sports photography, photo-journalism, commericals and for that matter anything is very easy with these technologies- the applications are endless. The best part of these panoramas is the interactivity it offers to the viewer – the user typically ends up watching the same scene more than once to get a different perspective everytime. CNN a while back reported the Haiti earthquake in 360

Most of the technologies either involve a multi headed cameras OR have a glass optic which can be mounted on a camera. The later is much cheaper than the multi head camera approach(you may check Immersive Media website for a multi headed camera). There are many companies in market which sell these glass optics – GoPano, 0-360, Egg Solution, Remote reality. These optics also come with a software which help you to “unwarp” the images you get from the camera.

Typically these glass optics can be mounted on any camera you have. Grab the images and import it in the software – Click and voila…! You have a one shot zero stitched panoramic image. You could also create 360 videos with a similar setup.
The images below didn’t take more than a minute, NO KIDDING, it was that easy – Click and “unwarp”. The software will create a interactive panorama like the one below.

Thats me and my girlfriend Pallavi in the panorama at Coopers Rock, West Virginia country side.

Drag your mouse in the scene and use Control/Shift keys for zooming in and out.


SomeFunAtCoopersRock360

The equipment I used to create this One shot-0 stitch panorama:
1. Canon 7D (you can use any camera)
2. GoPano Optic and the software sold by Eyesee360.

I am not done yet people- With the same optic, and any video camera you make your own 360 video like the one below/or the CNN haiti 360 video you saw above

Many readers in my previous article argued that you dont need a 500$ seperate lens/optic for making panoramic images like these. But a few photographers agreed to the fact that in certain situations where you would like to capture a panorama at that very instant – you can not use the traditional approach. Also think of making a 360 video -not many of us are familiar of stitching videos. Or are you? :)
The market for 360 videos seem to be catching up lately. There are different technologies which can help you make your own 360 vide0.( Immersive medias multicamera approach or EyeSee360 glass optic)..I work for EyeSee360 and hence I dont want to brag about our product or technology. But all I can say is, our stuff is better(if not anything definitely cheaper) :)

You could also create 360 videos using the optic like these -

Thats me and my room mate Mehta in his car. Again I used the same setup to record this video. You can watch the same video in an special 360 videoplayer called VideoWarp player available freely on the internet.

This small video I made, would help you get a better understanding how these can optics fit on your camera

Currently these optics cost around ~500 USD and I am waiting for the eyesee360s cheaper optics (~100USD) scheduled to go on sale sometime late this year.

About the photographer:
Amey Kanade is part-time photographer working with Enduring Tribute Photography. He likes photographing people, CD covers, weddings, travel and more recently 360 photography/videography.
His pictures have been published on NYtimes, Music CD covers, photography artciles on and off. He also works as a engineer/photographer with EyeSee360, Pittsburgh which manufactures optics for 360 video/image capture. Currently he’s also working on building platforms for hosting panoramic photographs/videos and making this technology more popular amongst casual photographers.

Panasonic HDC-SDT750 3D camcorder preview

Published on September 5, 2010 by in cameras
Panasonic HDC-SDT750 3D camcorder preview

Panasonic HDC-SDT750

I guess I must be in the minority here, but I’m just not as excited about the whole 3D craze as everyone else seems to be.  This is probably due to the fact that I have a visual disorder that results in the fact I get virtually no sense of depth from 3D.  One thing is for sure however, and that is the growing number of upcoming 3D capable TVs.

Panasonic is betting on the camcorder end of this with the HDC-SDT750.  For you event shooters, I can remember when many thought that HD was overkill for our business, and standard def was just fine.  Today, I shoot HD exclusively.  Who knows, the same may eventually be the case with 3D.

HBO throws a wrench in Netflix streaming service

Published on August 19, 2010 by in DTV

I’ll bet there’s a good chance that you are a Netflix subscriber.  I’ve been one for years, and really have enjoyed the service.  Since the addition of streaming on demand, and a Samsung player that plays Netflix online content, my wife and I have enjoyed many a film and TV show.  If you are a Netflix user, you may know that the content is a somewhat limited, and a little dated.

There has been promise of a major deal Netflix has in the works, to expand online content dramatically.  Even a promise of getting movies delivered about the same time they’re made available on premium TV channels.  Well, not if HBO is going to get its way!  HBO has control of a major chunk of film rights, spanning a number of major studios.  Instead, they want to restrict delivery to their own portal.  Oh great!   Another online portal!  Don’t we all want our content spread across 40 different web portals?

It’s not that I’m not willing to pay for it either.  I believe most out there would gladly pay an additional fee for the added content.  But we want it in one convenient place, and to not be required to have half a dozen boxes, and a computer piled around the living room TV.  Well guess what HBO, I was a subscriber to your cable service.  I just canceled my HBO  cable package, and I have no intention of renewing it.

More on the HBO vs. Netflix battle.

Television: Radio of the future?

Published on August 13, 2010 by in electronics
Radio of the Future

Radio of the Future

It’s a little funny when I think about a young person reading this title today.   I think the message would be quite the opposite as to what was intended in 1942.  Unlike then, radio is now in a decline.  Online content,  mobile apps that stream to your phone,  your computer, all offer tough competition to modern radio broadcasting.  Younger people (younger than myself anyway)  may not know that in the era of World War II, radio was the only network available.

One other fact about this time that might be lost on the young(er), is that most of the population lived a very modest life at the time.  It was the common belief that sacrifice would help our country in the war effort.  In addition, the government sold bonds to support the war.  Ads were everywhere, especially at the movie theater.  Perhaps we can learn something from this time?

Sorry about that tangent.  One thing I do enjoy about this era, is industrial design.  Many vehicles and electronic items, were influenced by the Art Deco movement of early 20th century.  I just can’t get enough of that stuff.   The graphic in this ad is a great example of this marvelous era of industrial design.

Microsoft Expression Encoder 4

Published on August 6, 2010 by in software, vegas

[thumbshot url=http://www.microsoft.com/expression/products/Encoder4_Overview.aspx]Microsoft Expression Encoder is the latest Windows Media Video encoder from Microsoft.  Some will scoff and say, why don’t you just use Quicktime??”  Well, most business clients use some version of Windows.  Installing new software on a corporate machine is often not an option due to security restrictions.  Besides, Windows Media 11 offers a very high quality video codec that is also very space efficient.  If your NLE does not output in Windows Media format, or does so poorly, this is a great free solution.

Those of us who use Sony Vegas Pro, and have had to deliver Windows Media Video files share a common frustration.  Even as of version 9C, encoding of Windows Media (wmv) files are painfully slow to say the least.  Depending on the output resolution, you can expect around 4X to 6X render times.  Very annoying, because Vegas is blazing fast when rendering Mpeg2 files.  One reason is because all processor cores are utilized.  WMV rendering utilizes only a single processor core.

Recently, I was faced with a job that would require delivering over eight hours of video as WMV files.  One final render started late afternoon was still running the following morning, and not even half way through!  Rendering each hour of video would take around four to six hours each.  Instead, I chose to output as HD 720P mpeg2 files, and this did so faster than realtime.  About .8X or so.  The segments were imported into Expression Encoder, and the jobs were encoding at faster than realtime!  Even with the added step, render times were under 2X using a quad core Intel based machine!

Energy efficient solar cell breakthrough

Published on July 29, 2010 by in energy
Graphene Photovoltaics

Graphene Photovoltaics

College of southern California experts indicate us a more economical use of graphene photovoltaics

Can you imagine people powering their mobile phone or music/video device while jogging under the sun?

A University of Southern California team has produced flexible transparent carbon atom films that may have great potential for a brand new breed of solar cells.

In a paper recently published by the journal ACS Nano, researchers stated that organic photovoltaic (OPV) cells have been proposed as a method to create low priced energy due to their ease of manufacture, lightweight, and compatibility with flexible substrates.

This work indicates that graphene, an extremely conductive and highly transparent kind of carbon composed of atoms-thick sheets of carbon atoms, has high possibility to fill this role.

While graphene’s existence has been known for many years, it has only been studied extensively since 2004 due to the impossibility of manufacturing it in high quality and quantity.

The University of southern California team has produced graphene/polymer sheets ranging in sizes nearly 150 square centimeters that in turn can be used to create dense arrays of flexible organic photovoltaic (OPV) cells.

These organic photovoltaic (OPV) devices convert solar radiation to electricity, but not as efficiently as silicon cells.

The energy provided by sunlight on a sunny day is around 1,000 watts per meter square, for every 1,000 watts of sunlight that hits a square meter part of the standard silicon solar cell, 14 watts of electricity will be generated, Organic solar cells are less efficient; their conversion rate for that same 1,000 watts of sunlight in the graphene-based solar cell could be only 1.3 watts.

But what graphene organic photovoltaic (OPV) lack in efficiency, can potentially be compensated by its lower price and, greater physical flexibility.

Researchers think it may eventually be possible to cover with inexpensive solar cell layers extensive areas like newspapers, magazines or power generating clothing.

In the meanwhile Prof. Ruoff and his colleagues of the mechanical engineering department at the University of Texas at Austin, are studying the basic science in the development of graphene-based ultracapacitors for usage in electronics and other fields.

Prof. Ruoff says batteries are relatively slow, they can store energy but require sometime to charge up, and then they distribute energy slowly, over time.

Ultracapacitors can be charged very quickly, in seconds, and discharge in a short time, but, today, they’re not able to store very much electrical energy.

The development of stable and less costly ultracapacitors is seen as a key step in using wind or solar-generated power, particularly if researchers will find methods to enable capacitors to store energy longer, that is not yet possible.

Even with their current storage capacity, the graphene devices could provide quick energy when needed in certain situations on the ecological way.

They could be used, for example, to absorb heat generated in braking an automobile or train, and store it for a short time, and then use it for the electrical needs of the vehicle (i.e. starting the vehicle or acceleration)

About the writer – Sophia H. Walker writes for the solar battery charger blog, her personal hobby weblog dedicated to tips to help people save electricity using solar power for small gadgets.

Your embedded video is too damn small!

Published on July 6, 2010 by in video, web
Postage Stamp

A Postage Stamp

This is something that has been bugging me more and more these days.  It really came to a head when I was trying to view a sample video from a fairly major effects plugin provider.  Unfortunately, the embedded video was so teensy, it wasn’t big enough to get any real impression of what the effect plugin was really doing.  Yes, I could click the “fullscreen” button, but on my 28″ monitor, it looked like an 8 bit video game.  And this is a company who should know better.

The fact is, the trend towards larger monitors has been with us for some time.  The old 320X240 typical standard for embedded video is scarcely larger than a postage stamp at the resolution of a large monitor.  There is no reason for video less than 640X480 in the case of a 4X3 example, or at the very minimum, 640X360 for a widescreen video.  This is the bare minimum in my humble opinion.  Another thing I can’t stress enough, is that you can always, and you should, upload higher resolution video clips, and then let your player, or Youtube, scale them down as needed.

Yes, I know there are some out there still using a 12 inch monitor at 640X480 total resolution, but no good ever came from catering to the least common denominator!
