I figured it out! Because we were naming the files like this: CAMERA_ORIGINALFILENAME_DATE_TIME, there would have been two sequences the programs would have been trying to reference, the original file name sequence, AND the time sequence. Therefore, it just wasn’t recognizing any of it.
When I changed the file name to CAMERA_DATE_ORIGNALFILENAME, it worked because the only thing that differentiates between the files is the original file name.
