Typically you would sync all media first. There may not be a defining action and/or distinctive sound in the media that allows you to effectively sync audio and visual in the part of the clip that you want to keep - so it is best to have the entire clip on the timeline to assist with syncing. In filmmaking, syncing audio and vision is made easy via the use ...

Another thing you could do with the tools you have:
Export the raw footage as a sound file, sync in audacity, then edit. You'll have less cuts to contend with, and everything will be in sync BEFORE you start editing.
Failing that, PC editing options are slim, but I have found the Sony Vegas family to be reasonably priced (look at vegas studio vs vegas pro) ...

A bit of a kludge but may solve your problem. Use a 2nd wireless mic that goes directly to your Canon HF10 camcorder as described here:

Looks to be about $250.

If both Record and Reaper support MIDI sync from an external source, you can use virtual ports with MIDI Yoke (or similar), and then a separate application (such as MIDIOX) to send the play/stop parts.
This isn't Rewire though, so the loop start and end points won't work.

Yes. The companies Spatz-Tech, HDFury and Faroudja have products with that functionality in their portfolio. But there are selling restrictions in many countries.

Ah, this used to be a notorious problem for people braving the new world of DivX ;-) 3.1 video with VBR MP3 audio tracks. It used to be commonplace for people to have to edit the framerate in VirtualDub (later VirtualDubMod); VDubMod provides a facility to adjust the video framerate to compensate for audio lag.
Golden rule for audio accompanying video ...

If the audio is in sync at the beginning and out at the end, check your frame rate on your sequence. You may have imported at 24 but the sequence is set to 23.976 or something like that. I had this happen to me in FCP7 with DSLR footage and double system audio. If you close your project and reimport your video footage to a timeline with matching audio you ...

Ableton Live can output MIDI notes/CCs pretty easily, so if you have visualization software that can use this to trigger visualizations, you should be set - you can just wire them togeter with some virtual-MIDI-port software (Bome's or OSX IAC or something like that).
Ableton also has some kind of MIDI Sync feature, although I hear it's fairly buggy. I've ...

Here is what I believe may help you a litte better. This I found after seeing all these, good suggestions, but not answers to your question, from Gavin Minnis over on a apple support forum.
This is my recommendation.
Step 1) Create your Keynote presentation.
Step 2) Record your speaking part (separately) with an audio recording program.
I recommend ...

Using one of this solutions will be more efficient. That's what you've asked for. It saves you time, because there's no more need to manually sync the presentation and the voiceover.
Free solution:
Keynote can record a running presentation with the mic-audio.
QuickTime X has also a screenrecord-feature incl. audio.
Lowcost solution:
Specialized ...

I don't know of any editor that do this natively, but there are plugins such as the RedGiant's Trapcode Sound-Keys (it has a free trial so you can check it out first) which allow you to this is a fairly easy manner.

Try writing a basic beat in a sequencer, where you can control the tempo. Play your sequenced drums up against the recording of the vocals only, and subtly vary the tempo until they line up.
The sequenced beat will be locked to a "click," so if you can get it to line up with the vocals, you now know the tempo of the vocals. You can set a metronome to ...

Unfortunately, even if you script a trigger for both apps at the same time they will not reliably be synced, so you are better off planning to sync in post production.
This can be very easy if you use a clapperboard or similar- this gives a sharp sound which is ready to line up in any editor ( some will do it automatically ) and takes very little time.

As long as the time code is reliable and your camera didn't drop frames, it should be as simple as laying them back to back and then syncing the audio. I normally recommend syncing to a point in the beginning and then checking if it still lines up at the end.
If not, a couple of factors could be in play. It could be that the timecode is just off from ...

The traditional way to change the tempo (bpm) for just a part of a clip in Ableton Live is to create a warp marker at the beginning and end of the section of your clip that you want to stretch, since you know where it should begin and end. Stretch the markers out so that it takes the appropriate amount of time. This process is called "warping" and it's worth ...

I suppose it depends on how much money you're willing to drop. Also, are looking to record the computer screen video while simultaneously recording the audio? or could you have an existing video track to then track audio to?
The last couple versions of ProTools support video in the multi-track audio process. Also Sony's VegasPro line does audio and video ...

There is a plugin called vocalign that will do this. It is designed mainly for aligning vocal overdub and replacment dialog but it should work for what you are doing. You can use it as a VST in audacity. It isn't cheap but, if my memory serves me correct, it has a fully functioning demo.

No matter how I think about it someone will have to be at the mixing desk momentarily.
If syncing the audio in post isn't an option, then I'd get another set of wireless transmitters, hook the transmitter to the mixing desk and connect the receiver to your camera. Then when the instructor does the demonstrations you could quickly go to the mixing desk and ...

Try the trial version of DualEyes and see if you can note the sync offset between the DSLR audio and the external audio, then create a new version of the external audio with the correct padding added or removed. Import the new external audio into the editor and replace or mute the DSLR audio.

Doesn't Live support video loading and syncing in recent versions? I remember seeing a screenshot somewhere of someone's project where he had loaded up a video and was working on the music synced to the video. But this is during production, and not live performance.
If you're looking for a solution that works during live performance, you can run a VJ ...

You can
use an existing visualization plug-in (VST or Audio Unit) inside of Ableton Live (see this forum thread)
use a separate machine with a line in or a microphone feeding a dedicated visualization app (coded in Processing or whatever...)

Assuming you don't need great quality and are ok with ip camera quality footage (which it sounds like you are), you could pick up several wireless ip security cameras and connect them via WiFi on the same network as a Mac laptop running Security Spy.

Use mkvmerge with

Synchronize, adjust the track's timecodes with
the id TID by 'd' ms.
'o/p': Adjust the timecodes by multiplying with
'o/p' to fix linear drifts. 'p' defaults to

Many Digital Audio Workstation software packages will have beat detection features which can detect and map the beats of a track to a tempo sync track. If the a capella tracks were recorded with a click track, then you should see the detected beats mapped evenly throughout the song. Otherwise, you have the option to either adjust the tempo of the original ...

You have both ends of the call in a single file and each end separate in it's own file. You could put each audio file on a track and find the beats in each. Then just align the tracks on the beats.

but I can easily turn it into a csv or other format by writing a
script to do so.
If you are scripting in something like Perl or Python, there are MIDI libraries that are very easy to use. Instead of CSV, grab a library and output the MIDI that you want. Then drop the MIDI file into logic, and you will have your timing data.
