Adding to Thomas' comments......the file size limit is 1Mb which would seem
to rule out using the FP server ext upload feature for videos since the
video file are likely to be far bigger than 1 meg (even with compression),
and with compression you lose the quality of the video itself.
The other option is to use a third party script that has an upload feature -
which in many cases can have the file size & file format type set in the
script itself, but again this depends on your host and what they allow you
to use on your server space with your account. Anonymous uploads (as a user
uploading through a form would be) may not be allowed (at all).....so you'd
have to have some other means for them to get these files to you e.g. email
to you, and then you upload them to your server.
If you're on a Linux/Unix server, the scripts here might help:
http://www.ezscripting.com - some of the most easy to use and to set up
scripts I've seen - amongst the various offerings there are free and pay-for
(advanced) versions of these scripts. The are database scripts for basic db
work using flat text files - the advanced version has 'file upload feature'
and there's a 'form to email' script that has an upload/email attachment
feature.
Otherwise there's a realm of resources on the 'net.
