Synchronizing sound
I am very disappointed with the sound quality of my camcorder when conducting interviews. I thought I would buy digital recorder and lapel microphone and synchronize with track they produce on the video. The operation seems straight forward in FCP X, except i know that, before I can turn it off, the digital recorder will necessarily keep running after I cease recording with my video camera and also, it shall be operating prior to the time I start recording. I am a one person operation. Does this create a problem with the sychronization if the audio on the recorder is longer than the audio on the camcorder? If FCP X's synchronization feature will solve my problem, can you recommend a suitable (i.e.satisfactory but inexpensive) digital recorder and lapel microphone that should serve my strictly amateur purposes.
