QTL to DIS Conversion: FAQ

What are QTL files?

The QTL file extension is associated with YUV images created using the SECAM standard, which was the first one to be taken up by European colour television networks and introduced in the 1960s. QTL can also be associated with images created using PAL, a television transmission standard that succeeded SECAM. YUV represents a type of analogue encoding of colour information or a colour space and QTL images are typically YUV 4:1:1.

What are DIS files?

The DIS extension is associated with the DKB Ray-Tracer, a piece of software originally created by David Kirk Buck and Aaron A. Collins, which served as a predecessor for the POV Ray-Tracer. The latter software has the capacity to generate images from text-based scene descriptions and works on various platforms. Though fairly popular on PC/MS-DOS platforms at its release, the DIS format is now obsolete. It can, however, be viewed and converted to more accessible formats.
