I have beenproducing high quality 2 mic audio recordings for many years, including recordings of mainly classical and choral concerts. A number of years ago I was asked to also make a video of some of these concerts. Most camcorders do not have audio that is good for music concerts because even if they record using 48kHz/16 bit sampling, they have AGC circuits (automaic gain control) which basically eliminate almost all of the dynamics, which are especially important for music.
Prioritizing your edit workflow is extremely important to ensure that the project you submit is one you're proud of. The real trick, is learning the difference between the quick touches that make big differences, and the time-consuming touches that casual viewers aren't even likely to notice.
Time and again, we've warned readers about the importance of audio in video. Audiences will tolerate -- some may even expect -- imperfections in a video's visuals, but they absolutely will not stand for poor quality audio. Tinny or muffled sound instantly breaks our suspension of disbelief; it can make it difficult to follow the storyline or really connect with the characters.
I have seen a lot of people asking about what to look for in speakers and how to get the most bang for the buck. So I thought I would post this article I wrote on the topic of choosing the best speakers as well as getting a mix that sounds good on anything from a mono tv to a high dollar surround sound system.
Although I never had complaints by clients about audio, I always wondered about this...
Volume levels are to easy to determine, since you can see the peak levels. So it's easy to make sure that your whole DVD has a uniformed volume level so the client won't have to keep raising and lowering the audio volume during playback.
I had the pleasure of auditing a portion of the videomaker basics of video production workshop a couple weeks ago. There are many basic rules when it comes to video, and there is a wealth of basic knowledge that continues to be the foundation for great production. Though I had been exposed to all of this before, it had been years since I had seen the fundamentals of good video production laid out so methodically. It caused me to really think about the basics again.
I'm using vg20 and a VG10 for interviews. I bought a Tascam DR-40 to get a better quality (less affected by ambient noise) audio track. I'm using Premiere Pro CS5.5. I can synchronize the files accurately from a sighted clap but by the end of the interview (say 40 minutes) there's a lag between the video and the DR-40 even though all was well to begin with. I'm importing four .mts files directly to the timeline. Is it possible they are not entirely seamlessly joined and that the lag is due to small discontinuities in assembling the clips?
