Audio syncing question.....
Posted 01 May 2010 - 10:06 PM
I'm considering purchasing it along with a flash recorder/external mics. The camera shoots at 24p, should I have trouble syncing my audio? It's just like syncing film dailies, right? There shouldn't be any drop-offs in the 24p signal (like when shooting with older film cameras), right?
Now, for the basic film student audio question, does it matter if your camera is running at 24 fps or 30 fps when recording on a flash recorder?

Frame rate on your audio recorder must be set to the same rate as your camera. So, if you're shooting 24 fps on film then set your audio recorder to 24 fps. If you're shooting 24p on video then set your audio recorder to 23.976 fps (it has to do with the digital conversion of the picture and I don't fully understand this). If you're shooting at 30 fps film, set your audio recorder to 30 fps (either drop or non drop depending on the camera settings). Same with video. 29.97 for video.
There are no prosumer cameras on the market that adequately record audio. The circuitry is very poor and is generally an after thought. After all, they are tools for recording pictures, not audio. An audio recorder will yield higher sound quality and more control over the audio signal.

One thing to watch out for is that they may say 24, but actually deliver 23.976. Which is fine if the audio recorder also actually gives you 29.97. The test to do is to shoot a long take with both head and tail sticks. Getting the "point nine something" vs. "point zero zero" thing wrong will cause a sync error of one frame in about 42 seconds, so run the test for a few minutes to be sure of detecting it.
