Mavic 3 - File names S V T

[raytaylor]

Does anyone know the difference between the file names on the Mavic 3?
DJI_20250131141744_0001_S.MP4
DJI_20250131141744_0001_V.MP4
DJI_20250131141744_0001_T.MP4

I know the T is the thermal camera recording but S and V look exactly the same so I cant figure out what the difference is between them, other than it is recording the image twice and using up extra space on the card.
