I guess I'm really just playing Devil's advocate here, but I'd like to hear more about it so this is how I'm doing it:
for lazy doc purposes i find the internal mic on the 7d is fine. but you can also plug in a mic to avoid resyncing, like magician did. either way, recording sound separately is kind of a necessary evil if you're making something bigger.
lazy doc's fine and all, but I don't do those. Plugging a mic in I'm sure is fine for docs or really indie stuff, but there's no XLR so it's not very reliable.
Recording sound separately really isn't a necessary evil for anything but film or high production. You can mix straight into the camera on "real" video cameras. You just need a mixer... and I've had pretty good luck with sound just going from a boom directly into the camera and mixing it there.. you've got two channels to work with, which works for the basic stuff I do.
image stabilization (in most canon lenses) helps a lot. the motor makes a bit of a sound but it only becomes really apparent with silence.
I'm sure the image stabilization helps (does it pick up on mic?), but camera movement is still different. You can usually see camera weight with smaller cameras when they're not mounted.
the smaller sensor on the 7d significantly decreases the chance of jelly.Still looks pretty bad to me.
Maybe your experience has been different.
just convert with mpeg streamclip overnight and you're good.
more room for loss and artifacts.
Obviously, this is mostly nitpicking, but I'm sure some of this stuff matters and I just want different opinions. Truth be told, I may end up getting one for video sketches, but might stick to using the HMC150 my friend has for the short I want to shoot this year.
