Lets say it could only be 60 minutes at most. So you can't say that you want say, every Anglefan video with Amber. BUT you could say you wanted every Amber pie hit.
Or every Phoebe sliming.
Or every girl wearing white jeans falling into the mud
Or every nude girl taking their first pie in a scene
Or ................whatever
And let's say copyright/ownership wasn't a factor. So you could have scenes from multiple producers on one "clip tape".
I'd want the raw camera footage, without the cutaways to host Bob Monkhouse, from the wetlook "love boats" section of the "Bob's Your Uncle" game show of some years back. This was quite a good show where wedding parties, in their full fancy formal attire, would one by one get into slowly sinking boats in a swimming pool until one of the boats capsized. There would often be brilliant shots of people in really nice outfits stepping down into the half-filled boats and then sitting down, smart skirts, dresses, or trousers going into the water - but they'd constantly cut back to the host, usually at exactly the wrong moment. A collection of the raw footage would be priceless from a wetlook collector's POV.
We've had the "Make Your Own Compilation" option since Day 1... Although back then, in the DVD era, it was limited to just putting individual scenes on a disc... which folks can now do digitally via the download stores.
I'd go for 60 minutes worth of blackout skits that each end with a pretty, clean model taking a great pie hit... which could run to as many as 100-120 skits. If only there were 100 such skits out there! PieJinx/Pies Next Door was the only one who really worked the blackout genre (at least that I'm aware of), but his career was very short lived, and all of his female skits run end to end probably wouldn't give you more than 7-8 minutes worth (his videos were always padded out with outtakes, which were enjoayble in and of themselves, but for my fast-paced fantasy comp I'd just want the skits). The producer behind Pied Pinups often had a short little piece at the end of his videos that could work as substittues (they weren't really skits, more like promos.) I suppose in a pinch you could just use the first pie hit from any number of scripted videos, provided you could glean some kind of setup from just the dialogue/visuals in the 15-30 seconds that precede that first hit.
The best first pie hit taken by every model who's ever been pied in a WAM production. I know "best" is very subjective, but in our fantasy scenario, let's use each producer's own choice for the best single hit delivered to each model he or she has ever pied.
Now, if we kept this to basically just the hit and a few seconds of aftermath (averaging five sceonds per clip), we could work 720 unique models into an hour. I'm not sure there have been that many in the whole illustrious history of WAM productions, but I'll bet that, at minimum, it's not too far off. Rich has worked with over 100 different models, Anglefan and Lenny have probably pied even more, and there are a number of other producers (Neil E., Ariel, Messygirl) who have to have pied many dozens of models apiece.
