So, what does everyone else here think of the 5D mark II audio input/gain? I just filmed part of my documentary with a Rode Videomic connected and it seems to have much more hiss than when on my HV20. Anyway to solve this?

Nope :(

I actuallty had the Azden SMX-10 and the Seinhiser (mentioned in the B&H newsletter recently) and returned both because untill there is a way to work around the agc, there was just too mutch hiss to make eaither of them worthwile (but thats just my opinion)

Could you not easily remove the hiss in post? If the hiss is constant you could just sample some silence and then use the clip as a sample for Adobe SB hiss removal.

Does Sony Vegas have any parametric EQ control? You need to be able to target a pretty narrow band to supress hiss...

If not I'm sure there is an audio program that you can do it in. Just export the audio track and work on it then re-import it. Does audacity have a param. EQ?

This is probably the only option unless Canon gives us the option to override the agc.

sony vegas pro will take any number of plugins, like the waves stuff, which is xlnt... but i'm guessing that it comes with a noise reduction plugin.

the better way to do it is to simply use one of those inexpensive portable flash recorders, there are about a million of 'em on the market today, pro quality stuff... just use a clapper to sync the sound up with, record it with the canon as well, and swap the audio tracks in post.

such are the headaches when going with film-style shooting... even if canon turned off the agc, the portable recorders probably have better quality audio dacs and such.
