418 0x05 Shutter Time Line Offset, this can be used as an exposure control:
419 0 = use full frame time, 255 = no exposure at all
421 When var-framerate control is < 514, no exposure is reached at the max
423 0x06 Shutter Time Pixel Offset, like reg05 this influences exposure, but
495 leave at 1 otherwise we get a jump in our exposure control
