whitebalance Posted July 2, 2013 Share Posted July 2, 2013 Hi folks, I'm trying to import an audio track from a movie I took using Photobooth on my laptop during a rehearsal, to use as a reference to build upon, the movie opens and plays in QT just fine. However, when I import the audio into Logic the levels are WAY too high and the whole thing is overdriven out of proportion. This is what the waveform pretty much for the whole track looks like: http://www.snipsnaps.com/outside/lvl.png I've done this before and never seen anything like this. I thought it was a result of some overzealous normalization but I can't find any settings for that either in Logic or QT (I downloaded QT 7 too just to see if there are any ways to alter this behaviour but didn't find anything). Any thoughts? Link to comment Share on other sites More sharing options...
Eric Cardenas Posted July 2, 2013 Share Posted July 2, 2013 Open the movie in QuickTime and choose Show Info. Is the bit depth 32-bit? Link to comment Share on other sites More sharing options...
Eriksimon Posted July 2, 2013 Share Posted July 2, 2013 The audio circuitry in your Laptop has probably some sort of limiter built in, and - if that picture does represent the full waveform - it had to work hard, by the looks of it. In other words: you probably had your inputs levels set too high on your Laptop. Crucially though: how does it sound? Can you still use it?

All it tells me is it's AAC, Stereo LR, 44.100kHz, H.264, 720x480. Also looked in Properties but I'm not seeing the bit depth.. Link to comment Share on other sites More sharing options...

In other words: you probably had your inputs levels set too high on your Laptop. Crucially though: how does it sound? Can you still use it? That's the puzzling part: it sounds perfectly fine when played back in QT but is next to unusable when imported inside Logic. I recorded it on another laptop (my MBP that I can't check right now) and then just copied the file over to the machine I'm currently on (a 11" Macbook Air). I do remember that I had to uncheck the "Use ambient noise reduction" in OS X's Sound preferences because it was trying to be a little too intelligent as far as the sound quality and the result wasn't good. In case I had the input level set too high on the original laptop, would QT be smart enough to process the sound on the fly during playback so it doesn't have the sound levels through the roof?

whitebalance Posted July 2, 2013 Author Share Posted July 2, 2013 One more thing (FWIW): I've just found another movie file recorded a couple of days earlier, same place, same laptop, same everything and it imports and plays back fine in the same Logic session, no waveform from hell.
