I've recorded several interviews with my Canon 5D MKII and Zoom H4N. I imported both files into the timeline but the audio from the Zoom H4N doen't have an audio waveform until I zoom into the timeline. I recorded a screen capture but my mic wasn't plugged all the way in so theirs no audio. If anyone has ever come across this issue or knows how to fix it please shoot me a message.
Link to the screen capture.
I had to clean out the Media Cache to get the audio wave form working correctly for the Zoom H4N audio. I don't think this problem is exclusive to the H4N but it is interresting knowing where the error came from.
