4k and larger is now-a-days becoming a standard for shooting things like features and documentaries, PSAs and commercials and the like.
For our forte’ live streaming, switchers like the NewTek Tricaster and almost all others that we use so much are not a 4k device so its all HD for that now. What we hope to find out with a test drive in October of the Panasonic AG-DVX20, its newest 4K camera, is to find out is how the Image Stabilizer ...

In the beginning producers and on stage talent would communicate during live events using hand gestures, waving flags, jumping up and down…anything to get the attention of on stage talent or others behind the stage involved in the live event production. Sometimes it was important…like when the gas lights caught the stage fabric on fire at the back of the stage. Then along came technology, specifically the telephone and its many derivatives. One application of telephone technology was to create ...

The headline is correct. There is a way to combine the capabilities of some video switchers with a single HD video camera to create the impression of a three or four camera shoot. We did it yesterday for a live broadcast. The results are quite impressive…
How do you make a single camera look like four different cameras? You a need only two things using mature existing technology to make this happen: an HD video camera with an SDI output, and ...

We were asked to live broadcast the memorial services for two sheriff’s deputies on two consecutive days last week. The largest church in the region could not handle the over capacity crowds. After they filled the main chapel with 5000 people, they crowded everyone left into every one of the surrounding rooms on the church campus that they could to allow people to watch the 90 minute services. There was a problem however. None of the adjunct rooms on the ...

Oh my gosh! What have I forgotten? My company’s live video broadcast is next week and I am not sure that I have everything covered! It could be a disaster if I forget something! What do I do?
We don’t hear this very much when we are involved with a client in preproduction planning for a live video broadcast, but that is because we are involved. As the broadcaster you must be involved in advance, but what questions are important? It ...

All the high tech video equipment, audio gear and so forth does not guarantee a watchable and entertaining on line live video stream unless you spend the time to understand the order of a live event and incorporate as much of what is going on as is possible. This is done by actively paying attention to what is going on in a room and switching to the action. That is the art in what we do as Internet video broadcasters. ...

In the past few years, the pace of technology in media creation has been moving faster than ever before, driven by heightened competition between manufacturers and enabled by embedded microcomputer technology. Designers now have at their disposal tools in manufacturing materials and technology allowing them to realize designs that were just not possible before. Starting with computers where ideas are born, then moving to acquisition, onto editing and effects, then finally to delivery; all made possible by dense computer micro-chip ...

4K Video recording presents some new challenges and opportunities for cinematography and video in general, but what is 4K Video? 4K Video is also known as Ultra High Definition Television of UHDTV for short. It has been accepted as a standard by the broadcast industry and has broad application in video and cinema work but it is still a ways off from large scale consumer acceptance. UHDTV is defined by display devices or content having a horizontal resolution of 4,000 ...

Video image stabilization is an important feature of contemporary still and video camera lenses. Image stabilization or “IS” for short is accomplished in the lens of the camera. It works by reducing the effective area of exposure of the imaging sensor(s) in the camera by 10-15%. If the camera shakes while recording, the camera uses that 10-15% border area to smooth the image. IS is popular for handheld work. We use IS for tripod mounted shots that require a medium ...

How much Internet bandwidth do I need for live broadcasting? At our company we go around and around on this subject. There is no absolute right answer, other than the more the merrier. So let me give you the tools you need to determine if a venue has “enough” Internet bandwidth for you to send a single live video stream out to a CDN. We will not discuss the CDN to end user network issues in this post.
There are two ...
