  1. What is the best way to synchronize audio with the video? Which software do you use?

  2. A visual clap is good.

    Corel Video Studio X5.

  3. You can manually sync it in an editor

    or an automated option is Plural Eyes

    Is there a great tutorial online for the manual sync?

    You need to be MUCH more specific.
    People here are assuming you used a video camera to record something from a distance....and also had an audio recording device recording THE EXACT SAME SCENE but in closer proximity.....is this correct?

    You can get free clapper apps for your Android tablet or iPad.

    But if you ALREADY did a shoot without synchronization, you will have to add both A+V from your camera and A from your separate audio recorder and load them both into an NLE, put them BOTH into the timeline (for each set of clips) and zoom in until you can see the waveforms. Then try to match the waveforms. Unless they're coming from the same source, they'll never look exactly alike (especially if one is nearer), but you can often see when the onset/rise of a certain wave is starting at the same time in both tracks (you just shift one track earlier or later, leaving the other alone). Shift in Large increments (seconds), then in increasingly smaller increments (frames, quarter frames, milliseconds, samples) to fine-tune it.

    There is a reason the pros do it that way - you just found out why, and I bet you won't forget again...

    You are right!
    I have photographed a wedding on the beach. My wife has filmed at the same time. I have put a microphone on the groom. Not the bride beacause her dress didn't allow me to hide it for abvious reasons. I have recorded the sound through my Zoom voice recorder. I have set up two DSLRs on tripods on both sides of the bride and groom and my wife recorded the wedidng ceremony. It was a beach wedding with considerable wind noise in the background. The two cameras were 10-15 feet away from the bride and groom. What I have is the voice and video recorded by the DSLRs. I haven't out an external mic on the DSLRs because of the wind noise. I have relied on the Zoom entirely.

    Let me know if you need more details!

    I'll piggy-back on the thread, since I have a similar question.

    Someone I know bought a second-hand Panasonic camcorder. While the video is good, the audio isn't.

    As a cheaper alternative to getting a wifi microphone, I was wondering if he could just get a voice recorder, run a clapper app when starting, and sync both streams using eg. AviSynth (At $300, PluralEyes is too pricey). Does it work well?

    Thank you.

    @Y.A.L.I.,
    Yes, I own a Zoom H4N myself, which (at the time I bought it) was the top of their voice recorder line. You can do the steps I mentioned and get dead-on sync, though I recommend that you break your clips up slightly (<1 Hour each) and sync each so you don't have Drift Buildup. Have done this for semi-pro shoots and it works great.

    FYI: Make sure to put your Voice Recorder in a position that is optimal for SOUND, not for PICTURE. You'd be surprised how many people don't take advantage of that.

    Thanks for the info.

    Is there a voice recorder you would recommend below $100? I guess I'd like one that has a unidirectional mic so as not to pick up ambient noise.

    I'm also concerned about cellphone signals: The Tascam DR-40 I own picks them up when recording in a place with thick walls (so cellphones are trying harder to connect → when possible, I have to ask people close by to switch to Airplane mode.)

    And what's the difference between SOUND and PICTURE modes? Does it mean today's voice recorders also have a digital camera, and can be used to also record video → much bigger files?
