Topic: audio for video

[fleshoff]

I have been directed to this forum by several sources so here goes...
I record audio using a shotgun on a boom going into my current video camera, this has been great and uncomplicated and am very happy with the audio. Unfortunately I am switching cameras to one that has auto gain control which can't be disabled...no good. I guess I need the external recorder option but of course am on a tight budget. The H4n has been the standard recommendation but even that seems too much in both money and features, maybe I'm dreaming.

I'm not using an XLR mic, it is the Rode VideoMic with 1/8th in jack
I really only need one track mono
I just want something that can record with that 1/8th in jack at something like 44-48 kHz and control the level going in. Would like to monitor via headphones while recording but not absolutely necessary (I can configure something if need be)

I have even experimented with my iPhone but I get clipping running into that with my shotgun, however if I could resolve that life could be good.

Yes, people use the H4n, but the previous version had trouble syncing back to picture.
I've used the Edirol R-09HR at 48k and editor didn't have any problems.
Forget about those Galaxy or Dynasonic units.
Sonys look good.
Marantz PMD 620 would be good.
Fostex FR-2LE is good with video.

You get what you pay for.. there isn't any shortcut.

maybe its luck but i have had great success dubbing my fr2le to my canon mini dv
with that said does your new camera have mic/line in period? you just can't control the gain right
you might be better off getting some sort of attenuating cable and going directly into the camera
i have tried this 2 times recently and it came out good as a whole, with one more run  i'll have it perfect and save myself dubbing all together

[fleshoff]

I'm getting a canon 7D which does have a mic in, it will be similar if not identical to the 5D I suspect with audio. Not familiar with an attenuating cable but would like to hear more.

an attenuating cable cuts down the signal by _db (whatever its made for)
i have a -20db from microphone madness

so lets say you have the new camera and it has a fixed gain of 10db - the cable i have would cut the incoming signal down -10db from what it is
basically getting rid of the 10 db the camera adds and cutting it another 10
the extra 10 might or might not be a issue but you can always boost the signal in post production if need be

attenuators are "common" for taping out of a soundboard, there are many xlr version, the mic madness one i have is a 1/8

[fleshoff]

But isn't this different than an automatic gain control which would I would suspect act somewhat like a compressor raising the quiet parts? I would think adding this cable would simply cause the AGC to raise the level of everything higher and thus raising the noise? I'm an audio dummy so if I'm ignorant please excuse.

I have used the Rode Video Mic with an Edirol R09HR on a 'prosumer' video shoot. Worked perfectly. Impressive sound from that rig.

I realise this is over budget, just a data-point.

oh sorry i was thinking it had a fixed gain across all freq

Yes, people use the H4n, but the previous version had trouble syncing back to picture.

What problem was that? Sliding out of sync? A clock problem?

Possibly basic technique? Once you start separating the audio from the video (which is very common), clapper boards come in handy

I have never witnessed sync issues with the scenes I have worked on. 99% are less than 3 minutes. The main issue is aligning the audio aligned in the first instance after that it's always been OK for me. A hand-clap in front of the camera can be useful, you just align the remote audio to the camera audio clap-spike.

3 minutes is nothing though
typically when people have issues its after 30, 45, 60 minutes
the lag grows and grows and sooner or later you notice it

IIUC, the Rode Videomic is powered by an internal 9V, so you don't have to rely on plug-in power at least:

The Dynasonic/Galaxy you mentioned have virtually zero field reputation, and the specs look dodgy:
http://taperssection.com/index.php/topic,106904.0.html

For the money, there are a lot better recorders to be had.
Cheap recorder with quality 1/8" mic in, decent gain and 44-48kHz?
iRiver H3x0 (from $60 used, but 44kHz only)
DR-07 (from $140 new)
MT II  (from $150 new, but mic-in is probably better on the DR-07)
etc...

The other recorders mentioned in this thread are of course even better, but all in the +$300 range (which you said you couldn't afford).

[fleshoff]

Fantastic, thanks sunjan

[rastasean]

Although its big and heavy, it does have a hypercard pattern and pretty quiet.

I'm speaking of the Rode NT3

There are XLR to 1/8" cables or one of these:

Thanks but I'm all good with the Rode VideoMic. I've been using it for about a year and want to stick with it.
