| As you're editing, it's important to listen for audio problems, because FCP can't "hear" bad audio the way your ears can. It might tell you when the audio clips or causes a certain level of distortion, but it can't tell you that your mixes aren't perfect, or that there was noise in your original recordings. If you hear problems, such as audio artifacts (clicking, beeping, stuttering, scratching), unexpectedly high audio levels, or a lack of filtering effects during playback, investigate what might be causing these problems. For help in this investigation, consult the following table, which will point you toward the possible cause of your problem and the section you can read to find out how to fix it. Audio Distortion Problems at a Glance |
|---|
Type of Problem | Symptom | Possible Cause | Solution |
|---|
Audio artifacts occur during playback | #1: Clicks, beeps, or stuttering during playback in Viewer or sequence | Capture settings don't match actual sample rate for content being captured | Correct your capture settings; page 756 | | | #2: Artifacts occur during playback in a sequence; green line visible above clip in Timeline | Sequence settings don't match capture settings for all clips edited into the Timeline | Match sample rates of sequence clips; page 757 | | | #3: Imported audio clips click and stutter during playback | Audio clips are compressed as MP3 or MP4 | Convert audio clips to an uncompressed format, page 759 | | | #4: Imported MP3 and MP4 files click and stutter, iTunes Music Store downloads won't import | File formats not supported by FCP | Use supported file formats; page 760 | High audio levels during playback | #1: Loud playback despite setting optimal levels when shooting | Clips were captured as non-stereo and waveform interference is boosting total audio level | Relink mono channels as stereo; page 761 | Playback unaffected by audio filters | #1: Changes to filter settings seem to have no effect on output | Clips were captured as non-stereo, so filters apply to one channel only | Apply filters to both channels; page 764 | Audio sounds tinny during playback | #1: Audio playback sounds thin and tinny | Audio digitized using low sample rate or bit depth | Resample the original audio files; page 765 |
