Well, none of them go with the industry standards like 1920p30 or 480i29.97. 
Consider that the main notation expresses resolution and frame/field rate of
the encoded video itself and isn't concerned with how those frames were
generated. It sounds like you're trying to express how something was
processed before being put into that encoding/container.

For instance-
> 59.9SPS at 29.9FPS       (aka "30i") NTSC broadcast TV interlaced to 29.9FPS.
480i29.97 is understood to be digital "NTSC" with non-square pixels and 
drop-frame rate. It's often shortened to "480i" since NTSC seldom occurs in 
the wild as non-drop-frame. Nothing else is particularly needed.

Later,
