Video scaler

[6] When the U.S. cable network TNT introduced an HD feed in 2004, it controversially employed a stretching system known as FlexView (which was also offered to other broadcasters).

[2] Despite TNT's intentions, the system was frequently criticized by viewers of high definition channels, with some nicknaming the effect "Stretch-O-Vision".

In February 2015, FXX announced that in response to these complaints, it would present these episodes in their original 4:3 aspect ratio on its video-on-demand service.

[3][8] Since about 2008, some networks and cable companies have run high-definition versions of old programming that was originally shot on film shown in the 4:3 format.

The series producer, Sony Pictures went to the 35 mm film source, making new HD masters and cropping the top and bottom parts of the frame, while restoring the sides.
