That’s a tough one… So it seems the most you can bill them for is the boxing and shipping.
As to the other thing… well, after over 20-odd years of doing this job, I doubt any of us here could claim they *never* shot or recorded anything stupid/funny/potentially embarassing between takes, while checking recording/playback quality, testing mics, etc. in their whole career. How else do blooper shows happen.
The difference is the wiser guys re-recorded over those things that are potentially compromising immediately, before they could turn around to bite them later, or they eventually stopped goofing around the set to that extent. If you don’t learn that self-discipline, you eventually can get in trouble. Like cameramen on live IMAG jobs or multicam live- switched sports programs. Yeah, it’s all funny in the truck when the offline cameraman uses his 2-x extender to capture some audience member’s anatomical features in rich detail. Not so funny at all (especially these days) if the TD takes that camera to air by mistake or without warning, or if a spare preview buss feed is going to the green room where the guy who signs the checks and his wife are watching….
Remember Reagan testing the mics before a National Address with that “We start bombing Russia in five minutes” crack? Or the footage of the then-governor but now-current-President flipping the cameraman the bird, while they were “just practicing”? That’s all over the internet now.
From a purely technical standpoint, Dv to Dv dubs over firewire are lossless bit-for-bit clones, the quality is indistinguishable on a dub versus an original. So technically I suppose the clients are not missing out on the things they knew they were paying for if you cloned the tapes and…. maybe…. paused the record deck from time to time or cut out the audio during the dubbing. Time code discontinuities would remain however, and have to be explained, unless you jam-synched new timecode. However, if they have EDLs or logs that suddenly don’t match up to the footage, you’re busted…
Such a choice is however, ethically sticky.
If this is going to ever go to court for some reason, they could subpoena your still-existing originals and find the “discrepancies”, and that would look bad to a judge. Very bad. Plus, your whole conversation here is now public record, should they search the internet during discovery proceedings.
Is that as bad as giving them 100 percent originals now and having them hear you call them bad things behind their backs on the audio tracks? Or whatever it is you did then that’s making you blush now? I can’t tell you. This being an exercise video with bodies in various poses, I can only imagine what the extreme possibilities of your perceived transgressions may have been. Ah, rash youth! Or maybe you just insulted the client verbally, I couldn’t say.
You and your conscience will have to make this call. But on the bright side, everybody reading the thread has learned something useful today. I hope. Best of luck.
