If you want to go deeper into the subject of aliasing: Browse around through the Alan Roberts BBC camera R&D white papers on this site.

I love it when you talk dirty (as in "Nyquist Criteria"). N/4? N/2? God, that's hot! :)

damn, that was some pretty good lookin' footage. I kinda feel sometimes (maybe just in this thread) there's too much tech talk and not enough of the imagery and work that actually makes us want to keep shooting. Tenolian, thanks for posting that link.

Agreed, very nice work.

 

This one looks great too, very minimalist: http://vimeo.com/groups/8432/videos/7410185.

Isaac Brody has been shooting some informal tests with CapRock's anti-moire optical filters on his 7D.

 

He recently posted some footage on Vimeo, especially wide shots of brick buildings, slate roofs, etc.:

His threads on the topic are here:

In addition to real-world scenes, it would be fascinating to see shots of resolution charts with & without different-strength CapRock filters to learn more about how/if these filters benefit DSLR video.

The BBC allow the EX1/3 to be used on SD productions, the 5D is not considered acceptable to the BBC for SD Production.

For some reason Emmanuel/Filmaker's Gang/Roberto B etc etc seems to find this funny enough to use as a signature on Reduser.

Do you have any explanation for why he thinks this is the "most funny post ever?

While I can't speculate usefully on why he might find something funny or not, I can speculate that the BBC's concern about the 5D might be frame rate rather than resolution. Originally it was limited to 30 fps, which requires a conversion to 25 fps. Good conversions are expensive, and cheap ones look really bad. The 5D is supposed to get an upgrade to do 24/25, I'm not sure if the BBC has tested this yet.

The 5D was deemed unsuitable after it failed the ailiassing part of Alan Roberts test. I think it was the first test he made, no further tests were made.
