How do I move mp4 files from fotos to files on an ipad
One option is to do the following:

On your iPad launch the VLC app
Tap on the Network option
Enable the Sharing via WiFi option
This should present you with at least two http URL addresses
On your laptop, open your preferred web browser (Safari, etc)
Enter one of the URL addresses (NOTE: I find the numbered address is much more reliable than the one using your device name)
You browser will now open a Sharing via WiFi page
Use this page to directly upload/download files to/from VLC on your iPad.
