We are creatures of habit eh :-)
Of course you have to specify this option every time as the timestamps remain
the same in this case.
Why not? First of all it's just video files. What are the odds that the
contents of change and the file size will be exactly the same?
Using the defaults is fine but you should use the options which serve the
purpose.
If you want you can use find on the backup drive in combination with exec to
run the touch command on each file in order to update the timestamps. Then the
-u option you use with rsync wont update the file on the destination because it
is newer then the source. However in the end the result is the same as if using
"--size-only".
Don't nail me on this but the command could look like the following: find
pathtobackup -type f -exec touch '{}' +
--
