Best Solution For Canon 7D? Thinking About Taking It Back...

i bought a canon 7d thinking about taking it back because of the stupid "auto gain control"...

i did find a beachtek unit, and i was wondering is this signal that is placed in the right channel really apparent or is it truely in the 20khz area?

i have a recording studio/soundlab so i can shelf eq or brickwall anything above 17khz and that will eliminate it right?

also is most movies audio recorded mono with one condenser? or is it 2? cause i was thinking about 1 mic over the foreground for subjects in the main scene and one somewhere else for ambience...

any help and suggestions would be greatly appreciated!!

thanks

Dialogue is typically recorded mono. When multiple mics are used as with radio mics on each of several people, each mic is sent to its own isolated channel. Ambience should NOT be recorded at the same time you record dialogue! You want the dialogue tracks as clean of any interfering ambience as possible and you want any ambience tracks you use to be as clean of any interfering dialogue as possible. Trying to record dialogue and ambience at the same time is not a good idea.

Note that ambience does not even have to be recorded in the same PLACE as the dialogue, much less at the same time. Ambience is essentially sound FX, the sounds that fill up the background - conversation and clinking dishes in a restaurant, engines roaring by in a pit scene at an auto race, crickets chirping in the night as the hero and heroine make sweet talk in the swing on the front porch, that sort of thing. It is not room tone, the sound of silence. Room tone has to be recorded at the place and time the dialog is shot, ambience can be recorded any time and any place you can find the right sounds to make the scene come alive.
 
A lot of the time I spend on new filmmakers films is removing the "ambiance" they thought they should record. The best thing you can do for yourself in post is not record anything BUT dialog in production. If you can make peoples shoes silent and dishes not rattle and the extras NOT talk, your life will be much easier when you start to edit. AND you get to have your shot in the location you wished you had rather than the one you could get.
 
thanks guys!

i did some research and a guy on vimeo says the juicedlink is the quietest pre-amp, and even with the auto gain control on the 5dmk2 and 7d, he said that the dn101 works wonders because it doesnt inject a tone like the beachtek, its broadband...and i heard clips, it sounded good going into the camera...so if canon would get off their butt and get this firmware update to add full control of the audio in the camera, we all would be great...

they are doing that for the 5dmk2, that firmware comes out in 1 week.....no more magic lantern for 5dmk2 users....
 
If your happy then go for it. I would note that judging sound quality from highly compressed streamed video clips is, well not exactly the gold standard. Same goes for a lot of online advice. You can improve a bit your odds of getting useful advice by hanging out in a forum long enough to have a handle on who is knowledgeable. But even then their standards and yours may not match And they may be coming from a completely different perspective. And a lot has to do with who's using it. I recorded a bunch of stuff on mini Disk once that I had to turn over to a very picky editor. He still thinks I recorded it on DAT. But I used good mics and a mic pre that cost 4X the Mini Disk recorder.

Bottom line is if it works for you great.
 
also what is the best way to edit 7d footage in premiere pro cs4? i have avch and h.264 codecs and presets....the 7d records in .mov files, and its really slow...

heres my computer specs:

core i7 920 3.4ghz 8 mb cache
triple channel memory 3 x 1 gb ddr 3 @ 1.7 ghz
SLI 2x geforce 8800GT's both overclocked
WD hard drive 32mb cache

do i need more ram, my cards are pretty fast...
 
also i just releasized that the compact flash i bought is a scandisk ultra II with 15/mbps speed...yet the data rate of the camera is around 40+ mbps...this can cause problems with video cant it? like blur or skipping frames? also cause problems in the editing phase?

You're editing off the flash cards? DEFINITELY you need to have the files on at least a 7200 RPM HDD. Usually you'll want an external connected via firewire or eSata. Flash is not nearly fast enough for video editing.

Recording to flash is fine, but for editing you need to go off a HDD.

i bring the files to my western digital caviar black, 7200 rpms, 32 mb cache....i mean the camera records at a rate of around 40+ MBper second, yet the card i have is 15MB per second...

doesnt this mean that the camera will overflow the buffer on the flash card?

will this one do well? it says udma, whats the difference?

majority of your questions should be in the 7d forum, but while you're here:

transcode to another format. the camera shoots in an h264 codec, which is more of a delivery code than an editing codec. i use mpeg stream clip to transocde my footage to prores. i don't know what a good codec is for premiere as i don't use it. but mpeg streamclip is a free download and will convert any video clip to any codec you have installed on your computer. you can even do batch transcodes. i use it almost everyday.

you need to use a UDMA card, those are going to be more expensive, but very well worth it. UDMA is a faster standard for buffer refresh. i made the mistake of getting a non udma card and the cam's buffer would fill up. very annoying.

sound wise, although the cam audio sounds ok, its really not. occasionally i'll use the onboard audio but never for dialogue. only for broll or nat sounds. i use a zoom recorder and record all of my audio separate. some people have great results with the juicedlink and beachtek. but with the cameras 12 minute record limit i'd rather have my video get cut than my audio. that new juicedlink dn101 gadget is nice, however it only gives you 1 channel of audio.

here's a post i recently did about my workflow, it may help you out some.
