Even zipped
A video file is unlikely to compress at all so zipping won't help.
You can though split the file with the zip software and send the components separately. The recipient then has to re-combine the files to play them. If you make a self extracting .exe file all that needs to be done is for the two files to be put in the same directory and then for the first one to be run.
Unfortunately I recall that many email systems now reject .exe files (sometimes even if renamed) so we are likely back where we started unless the recipient can use the zip software to re-combine the files.
I think gmail has a limit of 20M of attachments.
Since storage and communications costs have fallen so dramatically it seems ludicrous that emails do not now accept larger attachments. The couple of tens of meg limit has been common for many, many years.
Mixture's various file-hosting service suggestions are without doubt the approach to take.
