Clicking Audio On Video Rendered Out Of Final Cut Pro X

i LOVE e-cards and i love this because it is so true.


thankfully i have really talented and incredibly smart friends. i continuously post questions to facebook praying someone smarter than me knows the answer faster than i can find it on google. 

my problem: clicking in my audio on my video after i rendered it out of final cut pro. the solution is below. sean hare - or "seen-har-ay" as we call him - speaks slightly above my level of understanding but i understood this. did i mention he emailed me this instead of posting it to facebook to save me the embarrassment?  he's a good friend with incredible taste in music and him and his wife are the best meal preparers i've ever seen. 

As far as the sound, make sure to check your Quicktime output settings and conversions on any of those files you are bringing into Final Cut.  It sounds somewhat like digital jitter to me that can occur when you have an audio file that is maybe 16 bit-44.1KHz and you are exporting the final output to 24bit-48KHz without doing an actual conversion on the audio.  Essentially what is happening is you are getting slight dropouts of audio information where digital information is not present or doesn't "sync" or jive with the rest of it. This can occur not only on import, but also export if you are not careful.
Another thing, make sure you are using a seperate drive for your Final Cut or Adobe scratch drive rather than the hard drive you are using to render the file to.  Problems keeping up with the buffer reading, then processing the file and writing it to disc can sometimes cause issues like this as well. 
Lastly, YouTube does employ some hefty compression to the final product so you will have some loss of information.  Usually that results in a more "thin" sound or "wispy" sounding audio.  It's harder to get around this and it's simply a product of preparing audio/video for web delivery, but having a consistent setting with all your audio files and outputs set to the same bit rate and sample depth is probably  your best start. 
I'm not really a final cut guy too much since they went to Final Cut X as I don't like the interface anymore, but maybe just double checking those audio files to ensure they are getting converted during import to your session settings will help.
