Batch command to change each file's creation date to match the information in the file name
open Terminal
type cd (including the trailing space) and drag the folder containing the files to be renamed into the Terminal window (the folder is probably Desktop/PRIMARYVIDEOS, so the command should look like cd /Users/Andrew/Desktop/PRIMARYVIDEOS)
press Enter
type (or copy/paste)

for f in *; do t=$(echo $f | sed -E 's/[-. mov]//g'); echo touch -t $t "$f"; done

press Enter
if (and only if) this results in a list of touch commands which look ok, type (or copy/paste)

for f in *; do t=$(echo $f | sed -E 's/[-. mov]//g'); touch -t $t "$f"; done

press Enter
