It's called "Bullet Time" and was popularized by the movie The Matrix. The effect is achieved by using many, many cameras to all shoot stills at the same time, and then effect of motion around the subject is achieved by animating across the different simultaneous images. To make the effect more believable, the still camera has to really freeze the motion (...

The BTS from The Matrix shows the early days of this technique: . The newest technology is Intel 360° Replay. Its customized for Sports Arenas and other places where there's a high value in making instant (takes almost a minute) 360° stop motion replays. In some setups a low number of low resolution Cameras are used, this ...

ABC, NBC, Comcast and others all have their own specs. What I've found is that 1080 progressive MP4 (h.264) at 29.97 fps (some rare cases need 59.94), with audio between 192-256 Kbps, usually does the trick. You'd obviously edit in ProRes, but to submit that codec to the stations is overkill. Some outlets will even reject specs that don't conform exactly to ...

Getting a file format that works for everyone is very complicated. However, if you are are trying for network news, it is safe to use MPEG-2 TS 1080i29.97 (CBS, NBC, CNN) or 720p59.94 (ABC, Fox) at CBR 50Mbps, 15/3 closed GOP. Audio should be 48kHz PCM. Local stations will accept MP4s, but you likely won't be happy with the results once it gets to air. The ...

Yes, there are. Let x:y:z is a chroma subsampling. Then x = 4 So the begin of the notation is 4:. y|x (y is a divisor of x) So there are 3 possibilities for the first two numbers: 4:1: or 4:2: or 4:4:. z = 0 or z = y So there are 6 possibilities: 4:1:0, 4:1:1, 4:2:0 4:2:2, 4:4:1, or 4:4:4. y + z determines the resulting color quality (higher is better). So ...

This depends entirely on who you are delivering to. Different broadcasters have different requirements. Most have a delivery spec sheet that you can request, or that they publish online. e.g. here's the BBC one.

In Russian we have term for them — плашка. English name I personally don't like — Lower third I was making them in After Effects. With animations, dynamic text, etc. There is a lot of tutorial (example), how you can make one. But I believe that without animations you can make them in a lot of other video editing apps. It is basically a type of Title (...

The numbers in chroma subsampling notation are the ratio of the sampling rates of the luminance, chroma difference, and alpha channel, if present (Whitaker, 2003). For example: 4:4:4:4 The color difference (and alpha) channels are sampled at the same frequency as the luminance channel. 4:2:2 The color difference channels are sampled at half the rate of the ...

Go Pro offers both headbands and helmet mounts for their cameras. Once you learn how to position and aim your head-mounted camera based on what you want it to see, you then only need a mechanism to start/stop the camera. WiFi support and an appropriate app can be helpful.

It made with body camera rig. Here is tutorial, hot to do it yourself, but you will need some adjustments to face it from front. Or if you don't need hands in the shot, you can use your tripod, how shown in this tutorial (careful, bad audio)
