What stereo mic for ambiance?
I am looking at the Audio-Technica BP4025. From what I can tell it seems to be the best at capturing audio without coloring it. Just curious what stereo mics you guys are using to capture ambiance for you videos.

Sony ECM-MS957 is what I use but generally to capture ambience as a separate recording to add in the edit or audio post, camera mic is mono and a panasonic AJ-MC700P.

That said, if I have to pick something blind, I pick an M/S pair of Sennheiser MKH 40 / MKH30. Works in all kinds of conditions (hot/cold, dry/wet), fits into a number of windbaskets for easy booming if breeze/wind is a problem, gives a stable sound stage where it's easy to locate the sources, and its sound quality is excellent. And the mid mic does not have to be a cardiod, anything from omni on up works, depending on what you're trying to capture and how far away from it you are/need to be. I am a fan of capturing in stereo when practical. I'm just not a fan of the sound of XY. If you want less coloring, tend toward SDCs, not LDCs. Anything more, I need more requirements from ya. |

Recently I shot a choral concert in a decent hall, and for which I had around 15 audio tracks. One piece featured singers lining the perimeter of the hall (singing the round?), and at the last moment I erected the BP4025 at the rear of the hall facing toward stage, in order to capture the initial processional into the hall and then music that my mains were obviously pointing *away* from. Turned out to be a terrific decision: the recording sounded great. HTH. |
Re: What stereo mic for ambiance?
Hey guys.
I intend to use the mic on camera while shooting b-roll. (provided the pre amps are worth anything on the X70) For voice I will be using either a wireless lav or shotgun. If I am not traveling on an aircraft and bulk and weight are not an issue I am looking at getting two Rode NT1's and setting them up for stereo recording in a basket. I also purchased (a few months back) some capsules for a binural setup. (nature recording) It has really cool stereo separation and looking forward to finishing that project soon. :-) I also have a parabolic dish for other recordings such as birds. I sort of went on a tangent there. So mostly I'm looking for an on camera mic to get good stereo audio recording. The new Rode mic is a nice design but more expensive and didn't seem to provide the dynamic range and seemed hyped in some frequencies as compared to the BP4025.... |

Re: What stereo mic for ambiance?
Yeah I guess I will need to play around with what works the best for the individual scenarios that I am confronted with. When I travel to San Francisco in March I will be carrying my gear. (I don't like to check baggage) It will be a run and gun situation. So in this case a camera mounted mic is what makes sense for ambiance. (to me anyway) For local stuff I can setup more elaborate miking using an external mixer/recorder. As an audio engineer I get that mic placement is key. Of coarse I am in a controlled environment in the studio. When shooting video the situation can be dynamic and requires you to use whats available right? Just trying to figure out what makes sense for what situation and prepare for it in advance. If spending $600 on a stereo mic that will provide poor results on camera even for ambiance its good to know now so I don't waste the money...

Re: What stereo mic for ambiance?
Greg, exactly what kind of ambient recording do you want? If you lock off the camera on sticks in the middle of a city (SF?) with mic mounted above, it might be OK. Just breathing, moving around, handling the camera, and shifting the stereo image (with the BP4025) can make for a really sub-par audio recording.
On an outdoor shoot of a large and crowded cultural event (think crowd noise and music), I mounted my BP4025 in a lyre-type shock mount on my camera rig, taking care to tape and isolate the cable. My sound guy used a shotgun mic for interviews, and I placed the BP4025 source way underneath for a very pleasing mix. Really, in this case, there was no other way to do it. If you simply want better audio than an in-camera stereo mic, then you're all set. ;) |
Re: What stereo mic for ambiance?
I would stick with mono on the camera and then add stereo in post as that way you have the best of both.
Remember every time you do an edit on your footage your stereo image will probably change with stereo camera captured ambience so you will just end up wasting time trying to fix it all or have to make it mono anyway. |
Re: What stereo mic for ambiance?
I would concur with Gary, add atmosphere in post. Trying to capture atmosphere at the same time as dialog is a waste of time.

Re: What stereo mic for ambiance?
Thanks Guys!
Rick I think you misunderstood. I would only use the stereo mic during B-Roll shooting. |
Re: What stereo mic for ambiance?
Are you guys suggesting the mic is probably a waste of money?

Re: What stereo mic for ambiance?
Typically, even for B-roll footage and "nat" sounds, the ideal location for the camera for visual framing, and the ideal location for a stereo microphone are often very different places. Remember that microphones do NOT "hear" sound like your ears do. We frequently have to "cheat" the microphone location to achieve the sound we need. I wouldn't spend a lot of money in hopes of recording good environmental sounds from the top of a camera.

A stereo on camera mic will probably get you all sorts of extra noises like servo, the body creaking and even the operator breathing etc. Add to that the image problems and it may be a better investment to buy one of the small all in one separate recorders and place it somewhere to get generic ambience for adding later in post. |
