    I import .m4v files to FCPX and edit it very little just trim and title it, then I export with Current setting and H.264(2 try), but when I watch the finished file, I can hear little popping sounds constantly over all time. the original file doesn't have that sounds. So I try using iMovie and it has no problem. I don't know if there was a problem in FCPX or my problem. Please let me know if I can fix in FCPX.

    Thanks in advance.

    Have you tried exporting to a format other than h264? I know there aren't very many options if you don't have Compressor, but perhaps you could do a test export to YouTube.

    Do you have x264 installed? I don't know if that would affect anything, but I wonder if it creates some conflict. (I'm having different issues with h264, myself, but it's on the import side.)

    Have you tried selecting another codec in the export window (CMD+E), like ProRes 422 for example?

    I have exactly the same problem on both Macs with FCPX (running Snow Leopard first, now Lion). Sound clips are fine while in the Media Browser but as soon as I drag them into the timeline they get some kind of "mysterious clicking noise" :)

    Tried every kind of export, video+audio, audio only, as MP3, WAV, AIF whatever... always the same problem.

    Perhaps Compressor can help?

    What format are those sound clips in?

    That problem normally happens with 44.1kHz mp3 files. Most often when that mp3 is rendered in FCP's timeline. To prevent that to happen, I import the file into Garageband or STP, then export it as an 48kHz AIFF.

    I have exactly the same problem unfortunately.

    My source files are extracted from a camera samsung wb550,
    video: 1280*720 @30fps AVC (Main@L4.0) (CABAC/1 Ref Frames)
    audio: 128Kbps, 32.0 KHz, 2 channels, AAC (Version 4) (LC)

    before exporting, all is fine, audio, video, transitions, ... very nice.
    when I export either video+audio or audio only, the result is the audio has missing parts (some cuts) let say 4 cuts every seconds.

    I know that original audio is 32KHz, so I tried to export the final project in 32, 44.1, 48 khz, I get the same result.

    I also tried to set the project as 32KHz by default, export the audio into .wav at 32khz, same result :-(

    Ugh I thought I was the only one! I have been waiting to release this video now for weeks because I thought I just wasn't getting something with the peaks in the sound, or thought maybe it was my new Mac having a problem but it isn't.

    I made a simple little song in Garageband to accompany this video I'm making and I've sent the song to iTunes to listen and it's completely fine. As soon as it's in FCPX it's popping throughout. I even hear the popping before export, it's as soon as it's in the timeline.

    Is there any fix for this??? SO annoying. I can't release this thing until it's done, and I need some of the effects in Final Cut so I'm not able to jump to iMovie. :(

    Same thing here. I get popping noises, but it seems only to do when I import audio clips "Jingle" that comes from iMove "11. If I import other audio from another source it does not seem to be a problem.
