I was having this problem this morning, so came here to ye gurus. Read this thread, then just tried restarting (didn’t even trash prefs or waveform cache) and voila, they’re all back…and this is on a very recent reinstall of my whole system where everything had been running swimmingly up until this morning. I also noticed at the same time i was having the “no waveform” problem, when i click play on the timeline, the video and audio would play on my monitor, but the cursor wouldn’t move on the timeline.
Oh, to wish for a real FCP Ocho rather than the jump to X (which i have not yet done anyway…still on 7.0.3). Sorry i wasn’t any help here, but hopefully your waveforms are showing back up?
thanks for helping out a bonehead!
