QTL to DDS 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 DDS files?

DDS (DirectDraw Surface) is an image file format that usually contains texture data, cubic environment maps or other type of data compressed using the S3TC (S3 Texture Compression) algorithm.
