suggestion for microhpne

[stefanocps]

hello i am to buy 2 sony 2500 videocam
Use is mainly for a psycologisr association: they want to film conference, and training session (2 person simulating a therapist and a client)
i am to look for microphone system and searching for suggestion in terms of type(lavalier, wireless etc,,) and actual model
Thanks!

Is there a MIC input on the Sony 2500 camera ?

I looked at the online specs and MIC input was not listed.

Also, how does the on-camera MIC connect to the camera ?

 

[stefanocps]

this is from manual
B
STEREO MINI MIC ( )
You can record audio using a microphone
connected to a MIC jack (PLUG IN
POWER) (p. 5).
MI SHOE MIC ( )
You can record audio using a Multi
Interface Shoe compatible microphone.
You can also record audio using an XLR
microphone, by attaching the XLR handler

( i don t knwow what xlr handler mean..is it an xlr to jack adpter ?

Do you mean the HXR-MC2500?

If so, you migt want to go back to the beginning and choose a different camera. The MC2500 shoots interlaced video only, which is a terrible choice for anything outside of broadcast television. If your intended distribution platform is Internet-based, you'll want to shoot progressive video. Yes, the video could be deinterlaced, but that has a negative impact on quality.

EDIT: The camera specs show 24p and 30p recording options, but cite the signal system as 1080/60i. That would seem to indicate that even the 24p and 30p options are recorded as 60i, which adds interlacing. For 24p, there can be a pulldown removal to restore it to a true 23.976.

It's funny. When I first looked at the camera's specs through Son's own info sheet, it mentioned nothing of progressive shooting modes.

EDIT: Sony offers the XLR-K1M XLR adapter for this camera, which adds about $700 to the cost of one camera setup. At this point, there are many better camera solutions in the same price range that offer XLR inputs as standard, and that shoot progressive video.

Assuming you don't choose a different camera, or want to pay $700 per camera for the XLR adapter, you'll have to get a separate audio recorder. If you do choose a different camera (with audio inputs), there are a couple ways to go.

With two people on stage, and needing to hear them both, the easiest way to record their audio is to put a lavalier and awireless transmitter on each one. Record them separately, with the easiest method here being to connect each wireless receiver to one of the cameras (and each camera operator will be actively monitoring with headphones while recording, right?).

Will there be any audience interaction? In other words, will they be taking questions from the audience at any time? If that is gong to happen, you'll also need a microphone solution to cover the room. This could be as easy as a couple of microphones on stands, asking audience members to step up to one of the mics to ask a question. This adds some complexity to the recording, though. You could also connect each of those mics to the other inputs of each camera, assuming you get cameras with proper XLR inputs.

Or, if you get a separate audio recorder, either get one that records more than two separate inputs (like the Tascam DR-680mkII or the DR-70D), or if you have to use a two-track recorder for some reason then you'll need to put a small moxer in front. In any of these scenarios, you'll need someone operating the recorder (and possibly mixer) who is actively monitoring with headphones the entire time.

There is a caveat with a separate audio recorder: at this level of production, you'll have no sync between cameras and recorder. You can expect the audio to drift over time when you place it in the timeline with the camera footage.

hi
where did you see that only reord interlaced?
i don t see it. i see both progressive and interlaced, seems strange taht a new product come out with only interlaced
and also there is a mic input(jack)
you undesrtand that noon using this camera is a professional in video, and none of the clip will have a commercial target
everything will remain for internal use, for learning, may be sometimes youtube some conference
but now they using an old 4:3 sony videocam...i think it is a big improvement!
also exlude separate recorder..durin training.they nedd to record a 20 minuts sesssion and suddendly watching it again for feedback purpouse..no complication with separate audio
i mean for what they do, and for what is their knoledge and competence should be more than enough

for your question..may be during conference, there will be audience asking questions tosepakers yes

 

[stefanocps]

yes it is hxr mc2500

Okay. It was Sony's own info sheet that failed to mention progressive shooting modes, though the camera's signal system is listed as 1080/60i, which would lead me to believe that even 24p is recorded as 60i, or interlaced. This may be for internal use, but putting Interlaced video on YouTube simply makes it hard to watch. It's not a matter of professional/commercial or not. It's a matter of preserving the video in the best way possoble for the organization.

With the camera offering a 1/8" (3.5mm) input, it is possible just to put a small mixer in front of the camera to mix the mics and feed them to the camera, except that the camera sends plug-in power out the mic input. This can create noise in the recording if it isn't properly defeated. There are XLR adapters that do this, like the ones from Beachtek.

You're looking at a minimum of 4 mics if the audience questions need to be recorded: a wireless lav system on each person on stage, and two stand-mounted mics on the floor for audience questions. If immediate playback is needed during the presentations, that rules out recording each mic separately across the two cameras' available inputs. This means that you'll need a mixer in front (even a simple solution like one of the inexpensive Allen & Heath ZED10 mixers) to send a completely mixed signal to both cameras, or at least a split of lavs to one channel and floor mics to the other.

I would still suggest you look at something like the Panasonic AC90A instead of the Sony. It has XLR inputs provided, and there's no confusion of 24p over 60i or actual 24p. It records true progressive. And, adding the cost of XLR inout adapters to the Sony, it's in the same price range.

 

[stefanocps]

well these are the formats ( i use pal)
PS (28 Mbps) 1920 x 1080/50P, 16:9
FX (24 Mbps) 1920 x 1080/50i, 25p, 16:9, 1280 x 720/50p, 16:9
FH (17 Mbps) 1920 x 1080/50i, 25p, 16:9, 1280 x 720/50p, 16:9
HQ (9 Mbps) 1280 x 720/50p, 16:9
is it not true progressive?

panasonic yes i saw it, it cost 250 euro more, which is 500 for two camera
may be better to invest thes emoney for a good audio sysrtem athat is the real trouble they had till now
as sai i can use xlr adapter and use xlr connection (since there is supply) is it correct? i don un derstand proprerly this part you said

i think for conferencin a solution with a small mic that gather 2 lavalier and a common mic to be pass through the audience can be fine..the mixer will output to camera input..
am i coorect?

You'll spend that 250 Euros per camera on a decent XLR adapter. My suggestion for the Panasonic is that you'll spend essentially the same amount as each Sony camera + adapter, but for a camera that doesn't require add-ons. This makes for a much simpler workflow.

The plug-in power is a low-level electrical current that provides operating power to cheap, consumer camcorder mics. If you're using one of those mics, that's fine, but if you are connecting a line-level source (such as from a mixer) it can cause issues if it isn't defeated. If the camera has an internal menu option to turn it off (which I haven't seen too often) then you have no problem. If it doesn't, you'll need a device that does, which is one function of the XLR adapter.

The other advantage to having XLR inputs, even with a mixer feeding the cameras, is that you will get a better quality signal over longer distances (longer than 10 feet).

If you have two lavaliers, you will need two transmitters and two receivers. Even the receivers that come with dual transmitters are actually two receivers housed in the same box. Either way, you cannot take two lavs over one wireless frequency.

A wireless handheld transmitter to be passed around would also work, yes. That adds a third wireless receiver, but with a mixer there is no problem working with three wireless systems.

i am concerning about this xlr adapter can t find useful information....they want a sony..and the next level is nx100..enough more expensive..
back to microphone
the best way to make thing simply(i say it again operator..can just press on off and move the camera..) the best thing woul be a kit..that with the sam eunit gives me 3 of microhpone..2 lavalier and 2 hand microhpone for example.so i only have the 2 output from central radio unit

And the Panasonic costs more than the MC2500, but not as much as the NX100. But if you add the cost of an XLR adapter to the MC2500, you're at the same price point unless you add the Sony adapter which is even more expensive. The NX100 isn't a whole lot more than the Panasonic, and offers the right audio inputs.

There is no simple solution for complex audio coverage.

ok..i am convinced about panasonc..i see much better
but there is something i did not understand about the power coming out form the sockyt of the mc2500. what if i connect a micropghone via 2.5 jack or a mixer line out there?
seems they want to stick to sony though..you ìknow.,..people with no knoledge stick a a famous brand
that will end un in going up o nx100 taht seems a real waste of money..i ll try to have them going panasonic
i know about each mic would have hi frquency., as i know there are device that have 2 micophone connected via radio, and mixe them within the unit i was wondering if there are bigger device that mix inside the device 4 diferent source via wifi..

btw panasonic has go audiovidea analog output( rca connector) they need to live view while recordine in another room..that means need a 15 mt cable...hdami is not good for this..so important that there is a rca audiovideo output

Again: the 1/8" stereo mic input on the MC2500 sends out a low-voltage electrical signal. It is meant to power inexpensive microphones, but it can interfere with other signals that don't need the power supply. The presence of that electrical output can cause audible sound interference (buzz and hum).

Yes, people get caught up in brand names. Here in the US, there's only $100 (90 Euros) difference between the Panasonic AG-AC90A and the Sony NX100. So really, it's not a huge difference and either camera will serve you well.

It does. The AC90A has an AV Multi output connector, which provides both component and composite (analog) video outputs, as well as stereo audio. The breakout cable with these connectors is included with the camera.
