How to Calibrate a Video Monitor
learn how to calibrate a video monitor in this short video tutorial. Monitor calibration is very important when colour grading. Computer screens vary dramatically in how they are set up and even same brand screens out of the box will often look different. This simple process will give you a solid starting point which means what you are looking at will remain consistent whenever you edit/ color grade.
I use a device called a Spyder 3 by a company called datacolor. It's a device that you place over your screen and it measures the light coming off your screen. The software that is supplied then suns a set of digital colour charts through your screen. The Spyder then measures the light and analyses the color frequencies. This process only takes a few minutes and once it's complete you can save the file as a preset. What you notice straight away is how different a calibrated screen looks when you flick between the before and after.
It's recommended that you recalibrate your screen every 14 days and you can set a reminder to flag up every two weeks.
If you don't work from a calibrated display then how do you know that your whites are white, your greens are green and your reds are red? If you have more than one screen then it's worth just putting the same image on both screens to see just how different the image can look across two different displays. Similarly your footage will look different from a laptop to a desktop machine and to a tv or once it's uploaded to You tube or Vimeo.
You can't control how someone is going to view your material and so it's vitally important that you calibrate a monitor in your set up for colour accurate editing and grading. This means that at least you know when you finish your work you can be confident that the colours are well represented and are accurate when they leave your suite.
