I have recorded a few video clips of a childrens' choir concert, using an OK external microphone to my Canon 5DII. Because the position of the camera wasn't really ideal for audio recording, I additionally used a digital audio recorder to record the entire concert from a better point of "view".
As expected, the "external" audio is much better than the internal audio, so my plan was to extract the audio portions from the hour-long concert file that roughly correspond to my video recordings and then synchronize them with the original sound (and finally either mix the two or mute the internal track).
My problem now is that the cheapo video suite I've got (which was a bonus add-on from my DVD burning software) doesn't allow me to easily and exactly synchronize the tracks.
Can you suggest a reasonable, not too expensive alternative here? I've looked at the sales blurbs for Adobe Premiere Elements 10, Corel Video Studio Pro X5 and Cyberlink PowerDirector 10; I've also read a few reviews, but I couldn't find this information anywhere: Can I synchronize external audio tracks exactly to the existing soundtrack of a video?
I was expecting that all these programs should be able to do this, but then I read a customer review on Amazon about PowerDirector where the author said that he was having terrible troubles with this (15 seconds misalignment in a 4-minute video that only became apparent when the final output was produced).
Or do you have other suggestions? My work-around idea looks like this: Edit the video until it's done, then export the audio track; import that into Audacity, synchronize it with the external tracks; export that new track and import it back into the video. But that doesn't sound like much fun...
