Is a compressor/limiter the right gear for me?

    Having done a few videos my self, I should say that I always mix my audio in my DAW and then import it to the my video editing software. The tools are of highest quality and easier to work with.
    That said, there are a very different things about compressing in the way directly after the output of a guitar or after the preamp or post in the DAW.
    First any compressing done on the way in couldn't be undone. Done before the preamp or after will give different results because of gain staging. Also I would never use a compressor guitar pedal after a preamp but before, as a effect would be acceptable if there is a reason. For exemple if an effect placed after the comp pedal needs a more EQ level to be fed to and produce more constant saturation or level reacting effect.
    The compression done after the preamp would, in my opinion, need to be of higher quality or special sonic qualities because inbox comp are so more precise and noiseless these days. So I feel you need to have a reason to use an outboard compressor (sonicly, character etc..)

    The performace you present is kind of classical music, maybe jazz and/or blues influenced.. What's mostly different in this style is an approach of fidelity of the playing which mostly offer more dynamic end results compare to modern music. That's why you had many comment saying it's just fine without compression.. Of course if your song goes to a mastering engineer, he might use a bit of compression to even out the peaks and obtain a level that stands up against other album of your genre. But at mix time, I'd be very carefull about compression.

    In the end you are the judge of what you want to hear. being the performer and producer. if the sound you aim is more modern, feel free to compress the hell out of it if it sounds good to you... Nobody can make that decision for you. ;)

    Thanks for the information and suggestions. Most of the videos produced are of an instructional nature, not really performance. But I guess I'll continue on without a compressor.

    I'm looking at the idea of a limiter again for recording instructional videos. I'm not sure if it's the right piece of equipment but here's the problem. It's very easy for the guitar to spike depending on on hard the guitar player plays something, likewise, it can go very soft. And I find myself having to constantly monitor the levels, and constantly adjusting them. For the purpose of instruction (talking and demonstrating), I do like to normalize because it just gives everything a bigger presence. but when I get spikes in the audio, normalization doesn't work well. Would a limiter allow me to set it so that nothing gets recorded louder than say -10 db, and then in my NLE, I can normalize it to 0 db for a nice big full sound on the video?

    You are recording digital? Then simply set the maximum so it doesn't clip and use the tons of dynamic range you have, then you sort it out in the edit, or post-production. Perhaps simply riding a fader, or maybe a compressor to retain at least some dynamic range. Limiters on record are pretty pointless - as you have the ability to record more dynamics that the playback systems can handle. Normalisation is a crude device to bring average levels up, as you say, till the highest peak reaches your normalisation maximum. Compression brings down the dynamic range, but in general - record every source separately synced, and sort out the balance when you are in a controlled environment. Compression, limiting and effects are bad news to use on the master source material. I never record via any form of processing - as it's often a case that you cannot undo the damage. A brick wall limiter might have a place if your recording is totally wild and uncontrolled.

    How is that done? I'm using a ZED10FX mixer. I try to set the level so it doesn't go above what I want it to, but the guitar is so annoying because it constantly does. Never stays at a consistent level.
    I don't know compressor, or limiter, but just something I could put in that would keep the recording from having spikes that I don't want. This isn't a music performance, it's an instructional video. I know hardly anything about this stuff, but I do know that when my recording levels are lower, and then I normalize in the software, it sounds infinitely better. When I try to record at higher levels to avoid normalizing, then it sounds worse.

    You bash the guitar at the point where it peaks and back off a bit. My tascam interface distorts quite easily on the instrument inpout, so you hit hard, watch the red light and back it off so no matter what you do it can't peak . I presume you are panning voice hard left and guitar hard right then blending in the edit/PP?

    Yes that's correct, voice and guitar and panned left and right when recording, there' also a piano that's panned in the same direction as the voice

    The piano could confuse things as you'll lose the separation?

    I panned them that way because typically the piano isn't going to be playing when the guitarist is talking
