Updating video

Hi,

I created a video for someone last year and she asked me now to just update a few things in the video to make them relevant for this year. The changes did not take me long…
Do I charge her my hourly rate (which will come out to very little because the changes are not big and won’t take me long) or a separate fee because it’s not a new video?

Thanks in advance!

I would charge a set price
which would include, changes, render time, uploading etc
