1. Digital Imaging Resolution and Aspect Ratios

2. Digital Images for screen display are measured in pixels (px). For example a HD frame is 1920 pixels wide and 1080 pixels high. The resolution is expressed as: 1920 x 1080. The Aspect Ratio is the shape of the image frame. For example a 4:3 aspect ratio is 4 units wide x 3 units high. A 16:9 aspect ratio is 16 units wide and 9 units high. To calculate the total number of pixels within an image frame simply multiply the width and height. For example a Canon 5D MKII camera has a native image resolution of 5,616 x 3,744 pixels. When multiplied the resolution is 21,026,304 pixels in a single frame. This is often referred to as 21 Mega Pixels or a 21 MP camera. 4:3 Aspect Ratio16:9 Aspect Ratio

4. When using stills in a video editor like Premiere Pro or Avid – use Photoshop to re-size. Observe the following frame sizes to ensure your stills are displayed at optimum. Be aware that some formats such as PAL, NTSC, HDV, HDCAM have non square pixels. Pixel Aspect Ratio (PAR) must be taken into account if using these formats. You will need to look up the appropriate PAR depending on format.

5. The individual pixels also have an aspect ratio – commonly referred to as Pixel Aspect Ratio (PAR). The pixels that make up a standard HD video image frame are SQUARE. Some video formats however have NON - SQUARE pixels which can cause confusion and squashed or elongated images if not handled correctly within the editing environment. The Colour Space of Digital Images for Screen is Red, Green, Blue commonly referred to as RGB. Print concepts and measurements have no place or application in Digital Video. Pixelation is an un-desirable artifact of digital images. Pixelation occurs when digital images are scaled UP beyond their native resolution.
