Video capture is part of live view . Turn on camera ->To start the video first we have to turn our switch from camera mode to video mode and press the start button to start or stop video . We can get the info buy hitting the info button which pop up’s a menu which displays on the screen from where we can adjust the setting according to our need , or else we can make these changes from the menu option too by hitting the menu button . There are different type of option for videos :- Setting frame rate per second (FPS) at which the video is shot . Video size at which it is to be shot at . Sound recording – Auto, Manual ,mode . File format at which it is to be stored at .
Video resolution which is displayed on the device is refers to the number of distinct pixels that
could be displayed in each dimension. It is usually quoted as width× height.
These are the following resolution present in the camera
⦁ 640x480 pixels
⦁ 1280x720 pixels
⦁ 1920x1080 pixels
Resolution varies from different cameras as all cameras are not same and not
all cameras have the same type of sensors .
A video file format is a type of file format which is used for storing digital video data on a computer system .
File formats like – NTSC and PAL are the file formats usually used in beginner level cameras .
Frame rate is the rate at which a video is recorded . The more the frame rate of shooting
the video more the video have smooth footage which help in getting great quality
footage for fast paced action shots and is better for getting slow motion of the scene .
Canon 600D has a FPS count to shoot videos up to 60FPS in HD and 30 FPS in
Full HD and the lowest FPS count can be at 24 frames per second .
ISO determines how sensitive our camera is to light. Using a high ISO (>ISO 640) if you’re shooting inside without a ton of ambient light. But as you raise the ISO, you introduce noise and grain to your picture, so you’ll want to do so carefully.
Aperture controls the amount of light reaching to the image sensor. The smaller the number, the more opening of the aperture is. The higher the number and so the aperture will be small. When the camera’s diaphragm is open, more light will be allwed to get in.
So we should use a small aperture, like f/1.8, to let a ton of light into the camera in lower-lighting situations. Aperture also controls depth of field.
Shutter speed is the amount of timefor which the camera sensor is exposed to light. The longer the shutter is open , the more light hits the sensor (and the more blurry on-screen movement will be). With a fast shutter speed, like 1/500th of a second less light will hit the sensor so that we can freeze motion and produce crisper, choppier footage.
When should use this general rule for shooting vedio: double our frame rate. we should shoot at 24fps, our shutter speed should be 1/48 If you’re shooting at 60fps, your shutter speed should be 1/120.
ISO-Keep your ISO number low when you’re shooting in broad daylight outside or under bright studio lights.
APERTURE- The higher the number, the less open the aperture is When it’s more contracted (closed), less light gets let in. While shooting outside, you might want to close the aperture to a larger number, like f/10, to limit the amount of light hitting the camera. To make sure everything in the shot is in focus (deep focus), stop down to a closed aperture (like f/22) to flatten out the image.
shutter speed –as discussed in previous slide about the shutter speed .When deciding your shutter speed for video, use this general rule: double your frame rate. If you’re shooting at 24fps, your shutter speed should be 1/48 .If you’re shooting at 60fps, our shutter speed should be 1/120.
In manual mode the focus has to be set by manually rotating the front section of the lens to choose the correct focus point required on the desired object and also to maintain the depth of the image .
In auto mode the focus of the scene determines it automatically and the internal mechanism adjusts the ring on itself to fix focus.
A camera stabilizer is a device designed to hold a camera in such a manner that prevents for unwanted camera movement, such as "camera shake".In some models, the camera mount is on an arm that protrudes in front of the photographer for this we should beneath the camera is a handle grip. Another variation positions the camera atop a fulcrum braced against the person holding the camera (photographers) chest .
An ND filter cuts the amount of light coming into our camera, allowing us to shoot at the aperture you want. ND filters are measured by the amount of light they cut out and that measurement is measured in f-stops. So, a 1-stop ND filter would allow you to get a proper exposure at f/2.8 instead of f/4, or f/5.6 instead of f/8.
Polarization filters are specially adapted glass that, when turne towards the angle to a light source, it will reduce glare from reflected surfaces. The most popular type of polarizing filter is circular to fit easily on the end of almost any lens,and also containing a free spinning element for quick adjustment.
White balance allows you to select the overall color/tone of the scene . White is used as a reference point as it is the perfect blend of all the color. Auto white balance works in a way that it analyzes and create an automatic setting that attempts to neutralize any color shift. This setting works well for indoor shooting where lighting is consistent.
white balance presets :-
Daylight or Direct Sunlight:- This option works ver well for general shooting daylight conditions where the sun is readily visible.
Shade:-It is used when we are shooting in sunlight and our subjects are in the shade. It tends to make the image more
orange to compensate for the bluish tones of the shaded areas.
Cloudy:- It is similar to daylight but compensates for the sky having some cloud cover i.e which cools down the color temperature. Many people prefer this setting because it is a little warmer.
Tungsten or Incandescent:- white balance setting is designed for shooting indoors with standard light bulb illumination.
Fluorescent:-It works best when shooting under standard fluorescent tube lights. However, some lights are daylight balanced, which would require the daylight setting.
Flash:- we won’t use this option when shooting video because we can’t use a flash.
There are different types of microphones used for recording audio while shooting any footage , whether we are interviewing someone , recording different sounds of background and while getting dialogues during a scene .
Anyhow it is not necessary to use an external mic any if we don’t have any on your camera . The mics on the camera can be used to record audio but for production level of videos it needs high quality audio thus external microphone is preferred over inbuilt microphones in camera .The inbuilt mics are called monaural microphone and external microphone are called stereo microphones .
Images and scenes can be edited inside the camera but for production level editing you have to prefer for the software. Editing inside the camera can be good enough for touch up to images and scenes .You can crop the scene as per your requirement. When an image is viewed in Playback Mode, we can perform basic editing such as rotating, cropping and and reducing an image is size. A camera may automatically fix red-eye that so often appears when we are using flash. Some digital cameras have more advanced editing functions. They allow us to make colors in a photo more vivid, either overall or individually to blue, red or green. we can convert a digital photo to Black and White, Sepia Tone and a variety of other options
There are 3 types of camera support :Monopod,Slider,Gimbal used for videos .
MONOPOD -monopods are very useful for stabilization and getting smooth footages which give a better result than handheld footage . It can also be used for tracking shots like panning the camera towards a moving object keeping the same stability , and to avoid jerks or and kind of vibration and remove jittering from your footage .
SLIDER – sliders are used to create a panorama shot eg - moving the camera in a office from one end to another showing the whole office like a panorama shot . It can also be used for smooth, swift and slow zoom in and zoom out shots and make a dolly shot out of it so as show importance to a particular object or detail in the frame of the bunch , it can be used for tracking motion by moving the camera to the same direction of the object in motion giving a smooth and jitter free shot .
GIMBAL – Gimbals are of many types . Some are handheld gimbals and some are body rigged gimbals. Gimbals are the best for getting smooth footage without sticking to one point of scene to get a singular perspective shot . Gimbals are motorized equipment which help the camera mounted over to maintain its axis thus providing smooth footage and covering different angels at the same time . It gives multi axis stabilization enabling moving with the camera at much more ease .
DSLR’s are very heavy piece of equipment which is hard to carry and not so convenient. DSLR’s causes difficulty to perform stable footage and sharp videos. It is preferred to shoot with a stabilizer, gimbal, or a tripod. Many equipments are required for your video shooting i.e. mic, stands, different type of lenses. Battery back up of DSLR’s are very short, it records footage upto 20-25 min in one go.
The first main advantage is image quality.
DSLR’s by nature have relatively crop light sensors in them, which serve to process the images you shoot into digital information.
The greatest benefit of DSLRs is that of interchangeable lenses, and with that, the control they can bring to the look of the video you are shooting. And by control, I don't mean just in the dazzling variety of focal lengths from super wide angle, to long telephoto that are available to achieve different film looks. I was referring to subject isolation. we can look at any major film release and notice how in many scenes the subjects are visually isolated from their background. The subject is sharply in focused, where the background is blurred out. This condition is achieved through selective depth of field with the use of faster wide aperture fixed focal length lenses, not zoom lenses.
A traditional HD camcorder may have a good zoom, but its widest aperture (typically f/5.6) cannot be compete with a fixed focal length lens- typically f/1.8 or better.
DSLR’s are far from being the perfect camera solution. It lacks a number of inbuilt features such as ND(neutral density) filters, etc.
DSLR are very linear, for different situations it is not very adaptable.
For different situations it always had to be interchange with different types of lenses according to the scenario.
Many accessories has to be carried for having a smooth footage.
Always different filters are to be used to cut reflections and increase softness in the footage.
Battery backup is not that reliable on dslr for videography as it keeps the live view on for shooting and it drains more power than usual for straight up shooting long duration of footages . It is preferred to have minimum of 2-3 battery packs for cameras and also carry your charger in case you run out of juice . Some higher end dslrs have additional battery grip capability to the camera which extends battery life and can be pretty handy to give a hassle free experience for shooting videos .
First of all we have to enable WI-FI signal from our DSLR.
Then turn on our computer and connect it to DSLR
After connecting we will transfer the file that contain the video/ videos and then paste it on our computer file.
After having those file on computer we can upload it.
Canon DSLR cameras have video shooting time of 25-30 min approx. as these DSLR camera are particularly based for still photography but due to which excellent quantity footage and high dynamic range hence it is also used for video shoots. Due to the limitations of time we cant shoot our video in one go. Extra battery packs or a battery grip is preferred for long duration of shoots
