optimally I was hoping to be able to use $N and $T by adding them to the 'prefix' field of Scene Filter. with the end result being the same in that $N would add the video file's name to the screencap file's name and $T would add a timecode for what point in the video file the screencap was taken to the screencap file's name.
I greatly appreciate VLC and any and all help would be greatly appreciated as well.
