Exif Tool

Change EXIF CreationDate of Video file

run in PowerShell: 

& '...\exiftool(-k).exe' -CreateDate="2016:05:13 11:41:32" "video.MOV"

Change LastWriteTime

(Get-Item "video.MOV").LastWriteTime=("13-Mai-2016 11:41:32")
or do it automatically if exif time is right 
& '...\exiftool(-k).exe' -CreateDate>FileModifyDate *.mp4
or 
& '...\exiftool(-k).exe' -CreateDate>FileModifyDate . -r -ext mp4 -ext mov
(sometimes you have to also do -CreateDate>EncodingTime)

Update LastWriteTime from EXIF information (for whole folder + subfolder)

This does not work for Videofiles 

& '...\exiftool(-k).exe' -r "-DateTimeOriginal>FileModifyDate" C:\path-to-folder\
