I have a batch I shot a few years back of a pharmaceutical laboratory. Back then I gave the clips (all shot in log profile) a certain color grade, which today I find kinda bad. Nevertheless these clips are selling pretty well since then. With the tools I have these days (ie DaVinci Resolve...) I can give these clips a much better grade. Does it make sense to upload a new, revised version?? (the visual look will be completely different) Would it impact the sales of my old batch? Is it forbidden by the agancies?
