Full screen credits on plain old broadcast television might still be reasonable, because how else do you get the information? But that medium is increasingly dead. We shall speak of it no more.
Full screen credits on TV as we increasingly watch it (DVR, DVD, IP) seem anomalous. Pack them into an information burst: if I want to read them, I'll pause and advance through individual frames. If I'm on a smart device, put the credits in metadata I can browse with that device. If the device is Net-enabled, put them on a page I can navigate to from the program. Don't make me sit through this stuff. Brand a little if you must, but if I care about obscure details, I'll seek out the information, and be very happy to read much more than you could cram into the credit footage.
Full screen credits in typical machinima (and other YouTube-length pieces) are a sign the medium is far too indebted to its older media parents, and is too slavishly following their inappropriate conventions. See above: viewer is almost certainly watching on a Net-enabled device. And a minute of credits on a five minute piece is a real tax on my time!
Further, there should be two default downloads/streams for episodic machinima:
- There should be the new episode for returning viewers (without credits, of course - we already saw them so many times. You can do a "previously" if the plot so demands.)
- And there should be everything from the first up to the new episode in a single download/stream for people coming to the story for the first time.
(Sorry for the explosion of highly subjective opinion. I don't know why I care so much about it. I remember I tried and failed to convince Hugh to do this kind of thing with Bloodspell.)
