The main advantage is cost. Historically, there were two main types of imaging sensors, CMOS and CCD. CMOS was historically used in digital cameras (because of the higher quality images it can capture, the lower cost, and the fact that digital cameras only have to capture a single moment).
CCDs on the other hand were historically used in video cameras, ...

I'm biased, but before anything else, invest in AUDIO GEAR. Far too often, filmmakers forget to keep audio on an equal par with picture. Invest in some good, quality mics. Shotgun? Meh...a good, all purpose cardioid like the reasonably-priced ElectroVoice RE-10 can hold you over for a while until you get some audio recording practice under your belt.

With low light levels your brightest signal will be close to the noise floor, so you only really have three options:
a camera with better low light performance (although this can only take you so far)
More expensive sensors can give a lower noise floor, allowing you to resolve more detail
a faster lens
As Jason commented:
If the widest aperture on ...

It depends on the camera. Digital sensors such as those used in DSLRs produce heat as they capture images. The main issue with extended video capture is the accumulation of heat in the sensor. If it gets hot enough, it is possible that either a) quality can be reduced temporarily due to increased noise or b) at the extreme end, damage to the sensor could ...

On DSLRs, a fast shutter can actually be better. DSLRs scan the image to sample rather than capturing the whole frame at once. This is why you get a distortion when you do a rapid pan. A faster shutter will result in stopping motion more clearly (less motion blur), which can seem a little harsher than the softness of film, but a sharper image may be ...

Generally speaking, it is not possible to use a camera flash as a light for video. A true flash is a high intensity discharge bulb which produces a very short (1/100 second or shorter), very bright burst of light. It is not designed to be used for constant light output and has insufficient power, durability or cooling to be able to operate as a continuous ...

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 ...

I disagree with the above answers.
Our visual culture and the century of cinema has dictated that we evaluate a 180 degree shutter as "normal", because that is how film cameras have worked almost forever, and that is how most scenes in every movie are shot.
180 degree shutter is the same as 1 over twice the frame rate, or 1/48 for 24fps.
If there is ...

This requires a repetitive motion and good lighting. You expose the position of the droplet on successive oscillation, but capture it at a slightly different spot on each.
Thinking about it from the perspective of a ball bouncing. On the first photo, I take a quick photo of the ball on the ground. The ball bounces up and then back down. I then take a ...

The biggest problem you are facing is that a DSLR typically records to the H.264 codec. That codec tries to minimize the file size and the only way to achieve that is to throw out negligible information.
Sadly human eyes are not sensitive to black parts of video, so dark areas are highly compressed. That means you will have a really hard time brightening ...

With the Sony alpha 5000 camera specifically, you will run into trouble trying to do continuous video capture (10 hours or more).
It will stop recording after 29min and 50seconds and then you will have to start it recording again.
Update: Per @John this only applies to actual recording. If you plugin the HDMI out to a video capture device, you can stream ...

With canon the first DSLR that can do that is the 550d (you need to set the movie mode to manual in the settings otherwise it will adjust automatically).
However i would suggest something with a swivel screen (600d and up) because it's very useful while shooting video. The 60d and 7d have more options for video (frame rate for one) but it depends on your ...

Some things to be aware of when shooting video (this applies to most DSLRs):
Rolling Shutter
Because of the way the 550d records each frame you can end up with slanted video when combined with fast motion. This is because the camera recordes each frame line by line, so each line is recorded at a slightly different time causing a warped effect. Its not a ...

In almost all digital video cameras there's no physical shutter, just a circuit that limits the exposure time. As long as that time allows the entire sensor to be illuminated and scanned, you should see no degradation of any individual frame. In this sense, as long as the minimum is met, there should be no visible difference between a fast shutter and an ND. ...

It depends no how far away you are shooting from and how centered your subject will be. You definitely DO NOT want a lavalier mic for your situation. They do offer very nice noise reduction while not requiring a boom operator, but they still require setup and distinct micing of each speaker. This will not work at all in your use case.
You absolutely want ...

The minimum software is hardware. You want specialized hardware for doing top quality live streaming encoding reliably. You could use something like the Black Magic ATEM television studio which includes 4 inputs and real time stream encoding capability to produce the conference really well or could use a cheaper stream encoder device that simply produces a ...

You should consider other options than Nikon/Canon. Even if they have proven DSLR can do really good video, thanks to 5D Mark II/III and Magic Lantern, they do not compete well against Panasonic and Sony.
If you compare 5D Mark III against a Sony A7S, you're going to have a much better video quality on A7S, thanks to its far superior sensor. Much higher ...

Amazingly, the best place to start with a question like this is Youtube. Believe it or not they have help file that explain the process with quite a bit of detail:

On Youtube itself many others have offered up video tutorials on how to do it:

I have seen some trainwrecks by combining Nikon .mov with Vegas Pro 10. After tech calls into both Nikon and Sony it was determined that my machine didn't have enough resources.
I need to upgrade from 32 bit to a 64 bit version of Win7, plus I need to go from a quad core to an i7, and from 4GB to 12 GB or better. I can use my Nikon files now but only if I ...

Good advice in regards to sound from dwwilson66.
My favourite accessory for my camera is this shoulder rig. There are heaps of stores selling them on eBay for under $100. They're great for how much you pay.

Your theory is correct, video is much less demanding of resolution than stills (1080p HD is only 2 megapixels). However you'll never get a truly sharp video image out of a Canon DSLR due to the strange interpolation/line-skipping that is used to produce a video frame from the full image sensor resolution, the result is always a lot softer than you would get ...

My personal and very subjective recommendation list:
A sufficient number of SD cards, battery packs and backup drives
Editing software (consumer SW like Sony Movie Studio will probably do)
Tripod with fluid head to allow smooth tilts and pans
At least one affordable objective with at least 2.8 aperture. E.g. Canon EF 50mm 1:1.8, Canon EF 85mm f/1,8 or ...

A fig rig would be an excellent choice for an action piece. If the fig is out of your budget range look at the Opteka X-Grip. Cheap ($30) and pretty flexible, especially if you mount it sideways instead of with the handle parallel to the lens barrel when the shot needs it.
Also if you have access to After Effects spend some time learning the stabilization ...

The CineStyle picture style provides you with a flat, desaturated image: providing the best dynamic range of any of the picture styles for Canon DSLRs. Technicolor provide you with a file that you can apparently import into your editing software to help you grade your footage. However, I never figured out how to use it and frankly, I don't think one needs to....

It is likely not possible to change in camera. For power and efficiency reasons, cameras generally use dedicated encoder hardware to encode the video in real time (this is why your camera can encode h.264 video live, but when you try to encode it on your PC, it takes longer, even though your computer is far FAR more powerful.) The caveat of this is that ...

Other than what you mentioned, the only other alternative is to use a third party firmware that highlights the points of highest contrast. This gives you a better idea of what is focused on by highlighting the edges that are sharp in the LCD. MagicLantern offers this for most Canon cameras. I don't know if third party firmware for other DSLR makes has ...

First, while sensor temperature is a real thing that can result in elevated noise levels, I'm not aware of a sensor in recent history that had a heat related shutdown (outside of harsh conditions anyway) or that could accumulate enough heat to be a threat to the chip. Most of the non-sense out there about sensor's overheating is completely uninformed rumors ...

Properties that are desired in these lenses are quiet operation, image stabilization, zoom construction that usually cover wide to short tele focal lenght and that have a constant aperture across that range. A perfocal design is good when using a zoom. These are a couple of general characteristics but they may be different for special applications.

I can't help you with the set lighting but the look of the video is definitely achievable in post and in case of a modern camera you definitely have to do a lot in post to get a believable "retro" look. After Effects is recommendable due to many great plugins that help achieving specific looks but any editor that has good color tools on-board, a blur filter ...

You can't do that. There is no tablet on the market (right now) that offers an HDMI input or any other physical display input. Your only option would be to stream compressed video over the USB (or Lightning on iPads) connection or Wifi to an app that displays that stream.
