What technique is used to display older 4:3 footage on a widescreen without cropping the image?

• A. Letterboxing
• B. Pillarboxing
• C. Stretching
• D. Cropping

Answer: (A)

Preserving the original framing of older content when the display has a wider aspect ratio is the key idea. Letterboxing does this by keeping the 4:3 image intact and adding black padding to the frame so it fits a 16:9 canvas without distortion or cropping. The full 4:3 image remains visible, and the unused parts of the widescreen frame are simply filled with black bars. Stretching would distort the image, cropping would cut edges, and pillarboxing would pad on the sides—both either altering the image or focusing on a different alignment—whereas letterboxing specifically preserves the full 4:3 composition within a wider display.
