I do some freelance graphic design for a small music label. For each release I create a cover, social media banners and a YouTube video with an audio visualizer and some fancy visuals.
I usually charge a very low price for the whole bundle per release, since most of the work can be re-used every time. What takes the most time is to create and render the videos.
For some of the earlier releases, we didn't create any video material yet.
Client: Hi, mate - Could you create video for "X Release" and "Y Release"? I need them right now since the release is today!
Me: Sure, I'll charge [extreme low price] per video, is that fine?
Client: No... That's insane! We could create ourselves, but you want to keep the project files to yourself, we respect that.
Me: I think it's fair, specially for a rush order. But okay then I won't make them.
Client: May we get project files for these tracks then?
Client: Why not?
Me: Because that's basically me giving you the finished product anyway.
