What if a particular client felt that this song editing service should have been included. A client leaving a review just MIGHT say that although you did a great job on their wedding, they felt you were nickel and dime them because they asked you to make a quick song edit for their first dance, and you wanted to charge them an additional $150 to do it when they were already paying you $2,000 as an example to do their wedding.
Who cares! I would only worry about the first part where they said you did a great job.
No you are not likely to specifically discuss "production fees" at your meetings, but you
should be explaining your contract to the client at the time of signing.
Again for the third time, if your contract is worded properly,
and you explain your contract properly to the client as to what's included and what constitutes extra charges, it negates the need to argue or try and get paid for, "production fees" afterwards.
"DJ TJ Entertainment, it's representatives and subcontractors, being licensed providers of copyrighted audio and video for both private and public events for the purposes of providing entertainment, agrees only to provide true and authorized reproduction of said copyrighted material either in part or in whole.
Any off site editing or custom reproduction of any such copyrighted material if requested by the client may be subject to regulatory approval and will incur an additional production fee of $xxx.00 CAD per hour plus fees for additional licencing if required.
Any off site editing or custom reproduction of audio or video of non copyrighted material as requested by the client whether provided by DJ TJ Entertainment, it's representatives, subcontractors, or the client, will also be subject to an additional production fee of $xxx.00 CAD per hour."
I've explained it many times to clients and never had anyone walk away from signing so it's not a deal breaker.
I also make sure to explain that it's only for any custom work needed to be done pre-event, hence the inclusion of the term "off site" which implies extra work needed outside of the event itself.
So if the client wants me to edit a medley live at the event with my choice of cue points, there would not be any extra charge and this always satisfies them.
Let's just agree on how many songs you want in the melody and let me transition between them at my own discretion, which is what we do live as dj's anyway.
In fact I think I'm pretty sure I can count on one hand how many times I've actually charged an extra production fee, and iirc, I think it was only for pre-syncing video and photos to music. And it wasn't even for an event that I was live mixing at, I was only providing audio and video. A couple of times for a celebration of life and I think a couple of times for a wedding anniversary where only background music was being provided along with photos and videos of their lives.
