Q: Perfect audio in FCPX timeline, distorted after export to QuickTime mov

Ugh. Same exact problem. Only noticed in the last month or two. Hoped the recent FCPX update would fix it.

My media ends up on Vimeo, and if I export to QT and then upload, it sounds terrible. Parts might be fine, but most of the dialogue is hideous-sounding. Sounds fine in the timeline. And if I have it upload directly to Vimeo from Compressor, it magically works. Which is frustrating, because then I'm not getting a save of the original export!

It hadn't occurred to me that this was QuickTime related but that makes sense. Maybe I'll try other formats. I am certainly using Loudness and volume filtering on the tracks, but I could swear this was not a problem for the longest time. And obviously, it *shouldn't* be a problem at all.

Seriously considering Premiere at this point, which is sad.

DO you hear the terrible sound in the QuickTime player?

Yes, absolutely. I don't have QT7 to test against, but I'm trying a recent export again at 44.1kHz. I feel like when I look at the timeline, it's the 48kHz audio that's giving me trouble—strangely, the 44.1kHz media comes out fine. And I *am* exporting to 48kHz in this case, so it makes no sense. But who knows, maybe that will help.

I definitely hear the problem, and it is annoying.

I had the problem today and I fixed it.

I had originally made the movie in FCP7 a while back and exported it to a ProRes .Mov file with a 48Khz 16bit stereo audio track.

Plays fine when auditioned in Finder and when played in Quicktime 7 Pro (my life saver as Quicktime X is not so good)

I imported the movie into FCPX v10.2.3  (El Capitan 10.11.4) and the audio had no bass and dipped and wowed like an old worn out tape.

So I opened the video in Quicktime 7 Pro and extracted the audio track - with no changes - AIFF, 48Khz, 16 bit stereo and saved it.

(in QT7, cmd+J (movie properties), highlight the audio track, and click on the EXTRACT button at the top. A new player will open in QT7 with just the audio.

Select EXPORT from menu (cmd+E) and select AIFF and click the OPTIONS button to ensure you keep the original settings e.g. 48Khz etc, then save)

I then dragged this audio file from the Finder and dropped it on the timeline in place of the existing audio track. Hey Presto! It was back to it's normal self.

If you don't have QT7 (and the version from Snow Leopard works perfectly in all versions of OSX) you really should track it down. Mine has all the useful plugins they abandoned in later versions of software. If you don't there are plenty of alternatives that will extract the audio for you.

Im having the same problem. did you ever find a solution?

Its so frustrating, I've been working on a project for so long and now it comes time to export it and the sound quality from some of the clips is crappy.

I've been using FCPX for 3 months, may its still premature to give any advice.

first time i edit my blog were not without any big obstacle, although i did not get perfect result. (cinematic audio sound like)

once i accidentally klick the audio enhancement (from flat --> to voice enhancement)

on my time line, sound was like "high pitch tone" and quite good, but after i export, the distortion pop out.

perhaps, we don't want to press this audio enhancement nor the Equaliser, so that the "high pitch" won't turn into a distortion.

hope it may help
