I have an iPad Air. I took a 40 min video with my iPad and am able to view it on the iPad. However, when I tried to transfer it to my laptop, I cannot see this one video on the laptop. It shows everything else that I took. How can I transfer it?

That seems to be a "feature".

You need to use some app like

If it is truly that large, I may have some difficulty with my Internet provider.

This data will not be flowing to your ISP. It will be flowing only through your router.
