Hi,

 

When in FC and you make your audio clips stereo and mark the pan at 0 in the center is it still stereo in that true stereo is a hard left or right pan.

 

Often times my stereo tracks will have one bar going a lot higher than the other when it's panned to the left. Thus when i put the pan at zero the bars go up at the same time. I'm taking it that I still have stereo because the clips are marked as stereo even though the pan is at zero/in the center.

 

Thanks,

joe

    Are you using a stereo pair to start with, a music track or an effects track?

     

    Often times my stereo tracks will have one bar going a lot higher than the other when it's panned to the left.

    It doesnt look like its a stereo pair from that description.

     

     

     

    Plugging in two mics into your camera; one in the left and one in the right channel doesnt create stereo, thats called dual mono. You would need to use a single stereo mic or use a stereo mic pair, set up as mid + side or A/B recorded to two audio tracks.

     

    Plugging in one mic and centering the channels pan, or panning full left and right on separate channels doesnt create srereo either.

     

    The simplest way to show stereo working  is to place a stereo music track in the timeline, they are locked together as a pair.

    Thanks for your help.

     

    To streamline this question if possible, regardless of what my 2 track dialogue looks like once placed on the timeline, if i highlight them and click stereo pair doesn't that make them stereo? That's what i originally did. Thus, if they're stereo pairs and I click on them and the pan is all the way to the left which shows one bar going a lot higher than the other bar when I play the clip. If I place the pan at 0 and the bars now go up in unison when played are those two track still stereo even though the pan is set at 0?

    >once placed on the timeline, if i highlight them and click stereo pair doesn't that make them stereo?

     

    Yes and no.  The clip will be a stereo pair within FCP, but whether or not it is actually  true stereo (with two discreet channels) to the listener depends on the audio content of each channel.

     

    As MTD showed above, in FCP when an audio clip is a stereo pair, the default pan setting is -1.  This routes the audio on the left channel to the left output and the audio on the right channel to the right output.  A pan setting of 0 on a stereo pair will simply route both channels to both outputs equally ... and a pan setting of 1 will reverse the output; left channel goes to right output and right channel goes to left output.

     

    To recap, the pan settings for a stereo pair are:

    -1 = left channel is routed to left output and right channel is routed to right output (default setting)

    0 = both channels are routed to both outputs equally (mono)

    1 = left channel is routed to right output and right channel is routed to left output

     

    The pan settings for a mono clip are different that those for a stereo pair:

    -1 = channel is routed to left output

    0 = channel is routed to left and right output equally (default setting)

    1 = channel is routed to right output

     

    If you made the clip a stereo pair but the audio information on both channels is the same, you'll essentially have a mono clip.

    what is the source of the audio - from a mic on a camera - is it a srereo  or a mono mic, is it  stereo music from a CD ?

     

    if its a mono or dual mono source you cant change it to stereo by just changing pan settings.

     

    you can only control a stereo track from a stereo source.

     

    stereo is created using two audio tracks containing time differential information which creates the stereo effect

    Yes, we were using a boom mic and and ambient mic that were not stereo, but my audio guy thought that our camera, Sony xdcam ex 1, turned both signals from the mics into stereo once in the camera. That was a mistake. We hope to go 5.1 in the end and  the 5.1 dialogue track is usually mono made from 2 track stereo so we'll have not as a dynamic sound relative to dialogue, but overall it would appear we would be pretty good. Shouldn't hurt us that much, ya think?

     

    It would appear I could either delete one of the two audio tracks, or take the stereo pairs and pan to 0. Wouldn't it be the same effect?

    Will you use this person again, I hope not?

     

     

    the 5.1 dialogue track is usually mono made from 2 track stereo

     

    eh?

     

    You say youv recorder two mics in mono. so where is this "2 track stereo" coming from.

     

    usual practice for recording speech from a single source such as location dialogue or a voice over is to record using a single mono mic to a single mono track, panned centered on the timeline, this has  voice  coming centrally between two speakers without any manipulation at all.

     

     

    It would appear I could either delete one of the two audio tracks,

     

    yes, to make a mono dialogue track, perfectly fine

    You could then lay the ambient track mixed at a lower volume with the dialogue to create your amiance effect

     

     

     

    or take the stereo pairs and pan to 0. Wouldn't it be the same effect?

    Again, what stereo pair?

     

    If youv recorded dual channel mono (we were using a boom mic and and ambient mic that were not stereo)    you do not have a stereo pair.

     

    Please read up on stereo recording, just Google it, as your still confusing techniques and terminology.

    I wasn't saying we recorded 2 track stereo i was mentioning that's how it is in 5.1. I was saying being that we didn't record it this way we are left with two mono tracks of which you explained to use the ambient track at a lower volume. I'm just trying to make the best of what I have. It's for a movie. Relative to 5.1 being we recorded the dialogue as stated is it that big of a deal in the final mix with bg music and sound fx? Will it be very noticable?

     

    Again, what stereo pair?

     

    If youv recorded dual channel mono (we were using a boom mic and and ambient mic that were not stereo)    you do not have a stereo pair.

    When I say stereo pair I'm referring to the two mono tracks layed down in FCP, highlighted and clicked to become stereo pairs. Sometimes both tracks aren't going up in unison, thus since they're mono tracks i was saying that when i pan them at 0 it makes them go up at the same time and I think sound better then when panned hard left.

     

    Can you direct me to a good source regarding most effective way to make audio 5.1? I'm presently adjusting all levels, getting clicks and hums out, inserting audio fades between clips wheere needed, mixing bg music with dialogue. I'm probably going about it wrong in your eyes, but someone was going to help me with making it 5.1 and wanted me to get everything adjusted as optimally as possible before we embark on 5.1.

    why, why are you linking two mono tracks as a stereo pair ?

    If you are going to mix these two tracks to get a good balance between dialogue and ambience, you have to treat them as individual mono tracks-thats the whole basis of mixing.

     

    If you set them as stereo, changing the level of one alters the other by the same amout, defeating the object of mixing.

     

    As an example,  in most small scale broadcast documentary productions with a couple of voice tracks, the only thing thats stereo is the music track!   Stereo is only added for atmosphere, Foley and special effects.

     

     

    All credit to you for adding surround sound but if you dont know how to mix mono correctly the 5:1 authoring is going to be a disaster.

     

    I have never authored 5:1    This is a specialist craft and it has to be done right. Theres no call for surround in broadcast here anyway. I always leave that to the experts who do this for a living so cant advise on that.

     

    If you dont have any (L-R or M-S) stereo recordings, you wont have any stereo at the end of the mix.

    Thanks for your help!

     

    The music in my mix will be stereo.

     

    Do you know of any good sources on mixing 5.1 in FCP whether here or somewhere else?  I've typed it into google haven't found much.

     

     

    Thanks again,

    One last thing just in case - are there any sources in this community where you can find reasonably priced 5.1 audio engineers and colorist?

    Well that should be easy; Google video or Audio production for the town and country your in.

     

    My guys are in Edinburgh if thats any good.
