Pixels & Pixies...
It’s the weekend when some of us get a few extra minutes to tweak or blogs.
Every week I try to find a couple of ways to make them better.
Yes this post by Michael Thornton is a bit technical but you can get it or find someone to help you with it.
And if you haven’t already done so, subscribe to Michael’s blog, you can’t help but learn something.
Pixels & Pixies...
<sigh> While this will be one of those boring technical posts understanding pixels is the crux of video and photography. And yes, Toto, there is a difference between pixels & pixies. They are not created equal.
Most novices fail at video because they don't understand the basic underlyingprinciples and their differences. Frame and pixel sizes between video, photography and monitors are different. Photography and computer monitors use square pixels, video pixels are rectangular and will be laid either horizontally or vertically depending upon whether they are digital or analog format - hence the 16x9 aspect ratio. This is the reason that your digital pictures will not fit into a video.
Today, most cameras shoot 720p HD, 1080i or 1080p HD. Their frame sizes will be 1280x720 and 1920x1080 respectively. Your imported graphic will need to be sized to one of the frames. For this, I suggest you use Photoshop or other good photo editing software.
1) Resize your photo to 1280 pixels in width - (see inset).
2) Set your Cropping tool to 1280x720 pixels.
3) Adjust your tool on your photo and crop accordingly (see screen shot below).
4) Save this as it is now set for the appropriate video frame size which can be used in either 720 or 1080 formats.
This is the basic building block, cornerstone if you will, that is used in all high end video work. Doing this on the front end, makes back end editing a breeze.
I see that your eyes are starting to roll upwards and you are getting that "deer in the headlights" look so I will end this tutorial here. Tune in to my next post as I will give you another spoon full of cod liver oil. This one should be a little more interesting...RadnorLake Photography & Video
