Filming+with+DSLRs+-+Frame+Rate+and+Resolution

include component="page" wikiName="mhstgj4m" page="Filming with DSLRs - Menu" editable="1" =OVERVIEW= toc When you are out filming, it is important to know what settings you should be using. In graphic design, we need to know the size that the design will be used on, the resolution needed (print or screen) as well as what colour-mode to use (RGB or CMYK). Yes there are more colour modes beyond RGB and CMYK, but let's just stay on topic shall we?

In videography, the main variable that you will need to know are //Frame Rate// and //Resolution//.


 * Frame Rate** is the playback speed of the video. There are many factors that will determine frame rate. Will your video be played in a theatre? At an Imax? Will it be played online or on a TV? Will your audience be in North America or Europe? These are factors that you have to consider BEFORE you film.


 * Resolution** is the size of the video. Factors that have to be considered for video size are HD, standard definition, web, DVD, Blu-ray, and Imax just to name a few.

Since we will be filming in manual mode with our cameras, it's important to know the difference between these two as well as shutter speed and aperture. Continue below to learn more about each item.

=FRAME RATE VS SHUTTER SPEED - SETTING THE RECORD STRAIGHT= There tend to be A LOT of confusion when it comes to the difference between frame rate and shutter speed. Let's clear up some of the confusion shall we? Visit the website below and see your teacher if you have any questions. @http://vimeo.com/videoschool/lesson/56/frame-rate-vs-shutter-speed-setting-the-record-straight

Why is shutter speed double the frame rate? 'Patrick" posted the following explanation on the website above.

The origins of the rule of thumb lie in the rotating shutter in mechanical cameras. Blocking a frame for half of the time and exposing it the other half of the time (180 degree of rotation of mechanical shutter) yielded a decent sharpness of moving objects and was taken as the default exposure time.

=FILMOGRAPHY ... AND MATH!= Ready to information overload? Ready or not... here it comes! There are rules when choosing your shutter speeds, much like the articles above mentioned. Here is a more in depth look at those rules.

=720p VS 1080i ... WHAT'S THE DIFFERENCE?= Ever gone into an electronics store and the sales person starts telling you a whole lot of gibberish about a certain television? "This TV can display full 1080p vs that one which is only 1080i" is something you might hear. But what's the difference? Have a look at the video below to find out more.
