That is a specially built enclosure called a Sound Blimp, for a still camera, which renders it completely silent, so they can shoot stills without clicks and beeps disturbing the filming.

Cheap (to make) LED lights will flicker at twice the mains frequency. There are many ways of overcoming this in the design of lights, such as using a larger smoothing capacitor (which makes the light bulky), using a dedicated progressive LED driver IC (which turns off some of the LEDs but not all of them, so the light dims rather than going out every half ...

The reason is very simple. LED's are not constantly turned on, but flicker at a very high rate, usually due to fluctuations in your powerline. Your video camera records at a fixed framerate and as such, you can see these black lines. One way to counteract this is by not using an LED light source. But you may be able to work around this by setting a slower ...

Just move the camera to the top of the composition. The 1st camera is the one Ae will render.

The answer is both "light: lots and lots of light" and the imaging system. But it is not f22 (which on most cameras would produce a surprisingly soft result due to diffraction limits). The "light: lots and lots of light" is really about having not only good key and fill lights, but also lights above and behind the talent, creating a subtle rim of light ...

Do you own a high-end smartphone? You can plug-in pretty much any microphone and have very decent audio quality. Some Android phones even support usb mics. So you probably need a cheap adapter for standard stereo or mono mics to work with the 3 channel type headphone+mic jacks in modern phones. Something like this: https://www.amazon.com/StarTech-com-...

General SDI vs. HDMI Information SDI is easier to connect to other professional equipment than HDMI. It is an all purpose signal, as opposed to HDMI that was originally intended only to connect to consumer display devices. There may be a slight advantage in quality where HDMI can be limited to 4:2:0 subsampling at certain resolutions, where SDI will usually ...

Production Software Used: PfTrack, PfMatchit, Boujou, Syntheyes, Nuke Camera Tracker... Student free use: Autodesk Matchmover All of the above software is used to 3D Match Move Cameras to video sequences. Most of them are very expensive. PfTrack is my personal favorite. Although all of the above mentioned software is used to solve cameras for video ...

There are two possible problems, first is that your camera does not appear to have SDXC support. 32GB is the limit of the SD and SDHC file system used on lower capacity memory cards. To move to 64GB, you have to move to exFat which your camera may not support, so the card may simply be too big. It is also possible the card is simply too slow to support ...

Good quality film cameras have a reflex viewfinder system, where "reflex" means that you're viewing through the lens, and thus you can judge focus by eye. To achieve this There are, er were, two basic strategies: Split the beam of light from the lens with a prism or half silvered mirror, meaning that most of the light goes to the film, and a bit ...

There are three key factors in your cameras low light performace: 1. Lens (Aperture) The lower your f-stop, the more light gets through to the sensor, you will also have a very shallow (narrow) Depth of Field. Often this is a requirement at night, since cutting off most of your light is generally a bad idea. When looking at any camera, see what lenses are ...

Yes, if you record a video in 4K, then downsize to 1080p, the image will look much clearer than if you shot the video on a 1080p camera. You can also zoom in up to 200% and still retain the quality in a 1080p time line. Why it may look better is because most sensors these days use chroma subsampling. On most consumer 1080p video camera products, the camera ...

That's a kind of tracking shot known as an orbit. This looks cool:

The Canon VIXIA HF R500 is the least expensive consumer camcorder (from a major brand) that I have been able to find. I own one and love it. It has an external microphone jack that is compatible with my wireless lapel mic receiver. http://www.usa.canon.com/cusa/consumer/products/camcorders/consumer_camcorders/consumer_camcorders/vixia_hf_r500

When I was first looking for a good portable camera, the LX100 was on the top of the list. When looking at research, the LX100 provides great IQ (at 4k) in a good compact device for the price. If you have not already looked at these sites, I would suggest looking up TheCameraStore review on YouTube, CameraLabs, Dpreview, and EOSHD. LX100 does also have ...

To drive an animation by another layer use the pick whip or the selection list to parent it. In the following example the Camera (layer) adopts all animation properties of the Null. Note: Camera is a 3d layer in your case, make sure 3d layer toggle is enabled for the Null too.

I've had my fair share of matching. C100 with 5D MK III, 5D MK III with 7D, 7D with C100, 7D with a Sony Camcorder. It's all a matter of getting two cameras that are similar in terms of resolution and how 'soft' the image is. For example, the C100 is incredibly sharp, like 4k sharp in 1080p, whereas the DSLRS I mentioned are quite soft. Although you can add ...

Look at it from a data rate point of view: a GH4 records 4K at 100 Mbps. A RED Carbon Fiber WEAPON records at 300MBps. That's 24x the data rate. Look at how very much more expensive it is to purchase a CPU that's 10% or 30% faster than "normal" and you might then have some understanding of how much more expensive it is to offer 10x or 30x the performance ...

Different angles are used for many reasons. Wide and/or long shots are used to establish the setting where the video is being shot. Medium shots are used to show the relationship between people and/or objects. Close-ups are used to see the expression on people's faces, or details like hand movements or manual operations (using a wrench or a food processor, ...

You seem to have a flickering light source that is out of sync with the camera's rolling shutter. Traditional lights You should first verify that you are filming in 60/30/24 fps in regions whose power grid uses a 60 Hz frequency, or in 25/50 fps for 50 Hz. If that is impossible to achieve, you can also adapt your shutter speed or angle to be a multiple of ...

Yes, they are used for adding visual effects in post. The mirrored ball is for creating an environment map or reflection map. These maps provide the same lighting from the real scene to the virtual scene where graphics are created to composite into the existing scene. I believe the grey ball is used for recording more diffuse lighting from all angles, ...

This is actually a collateral effect of the concept of rolling shutter. Most video devices do not expose all the frame area at once. They expose starting from one side and (up or down) and move from there. (The example has the camera rotated 90° so the effect is on the sides of the frame). This can be either a mechanical element that moves or rotates or an ...

The camera only plays a part in what makes a good, clean image. The most important parts are Lighting, Lenses and Knowledge of the person operating the camera. If you film in a dark location and have to crank up the iso, you will get noisy images even with a 20k$ camera. If you have proper lighting and use a low iso, a 1k$ camera can look really clean. I ...

For videography, the best bang for your buck is, hands down, going to be an entry level DSLR and a decent lens. For audio, if your budget can allow for it, I suggest getting a stand alone multi-track recorder. The Zoom H4n is a particularly popular model with videographers for its low price and decent (though not superb) audio quality. (Update: The H5 and ...

Remember its all about the story. How to tell the story. And the tools you use to tell it. Editing, lighting, special effects and sound (are the tools used to tell your story.) Remember: story, story, story. Starting out: A good entry level camera to start filming with by Tom Antos. (Note: The Sony Nex-5 is discontinued,...

A steadicam is one solution, but there are others. You could use a slider dolly, camera crane, jib, shoulder mount, or fluid head tripod, depending on the movement you want.

It sounds like you've switched over to Active Camera in your Composition window. You may need to switch the Composition viewport window to the camera you wish to use. Do this by selecting the camera in the dropdown menu at the bottom of the Composition window. Hope this helps!

Here is some reasoning based on numbers: You don't need a fast card for video. It is generally advised to use at least class 6 for video recording on a consumer AVCHD device: Max recording bit rate of AVCHD 2.0 is 28 Mbit/s and minimum write speed of a class 6 card is 48 Mbit/s, this should provide enough headroom even with an almost full card. ...

There are two main ways this was solved: 1. Measuring Focus When using this method, the focus puller measures the distances at every point during the shot, and then pulls focus to these marks, at times making adjustments when an actor or grip misses their mark. This still occurs today, however is becoming less prevalent due to the filmmaking styles being ...
