Aspect Ratio
What is aspect ratio?
- Aspect ratio is the different screen sizes on TV and Projectors, there is 4:3 (standard screen) and there is 16:9 (wide screen).
- We have different aspect ratios, but 16:9 (widescreen) came around in the last decade, despite films being filmed in 16:9 (widescreen) for about 50 years now.
Pan and Scan
- Pan and Scan is the format used to change a 16:9 (Widescreen) to 4:3 (standard screen) so people with 4:3 TVs can watch films shot in 16:9. Directors and film makers say that when 16:9 is converted to 4:3 you lose the full effect of the film.
- By panning and scanning you’re not getting the full movie, and miss parts of the movie, with may leave you confused.
Pillar boxing and Letterboxing
- Pillar boxing is when you have a video which is filmed or broadcasted in 4:3 (standard screen) to 16:9 (widescreen) TV. This means you get to black, grey bars either side of the 4:3 video on your TV. Images from - http://img.skitch.com/20081125-gnfshpthn96y4ysqrtywwt1yfd.jpg
