Waveforms taking a long time to show up
I was wondering if anybody else was experiencing this. I work with a lot of 2 hour+ clips, so I expect the waveforms to not be instant. However, it seems like they are taking an unusually long time to appear on the timeline (like, 30+ minutes in some cases). This is a real problem because I depend on being able to see the waveforms to normalize audio. One they are there, FCPX makes adjusting segments of my clip a breeze, but I’m finding myself waiting for long periods of time to do any work because of this.

This reminds me of Soundtrack Pro behaviour. It took also way to long. You might want to try a faster disc or raid to increase performance.

I can just imagine how long it would take Logic to draw two hour waveforms.
Seriously, that is more than a bite sized piece of data that needs to be analysed.

Doesn’t seem to be an automated normalize audio feature in FCP X. That might speed up your audio edit considerably.
Now if you were using iMovie, you’d have a normalize audio function in the Inspector to set your volume levels very quickly. Just one more missing function as Apple appears to have dropped useful functions from iMovie. Maybe in a future update…

Actually, I mix down 2 hour+ tracks in logic all the time, anywhere from 6 to 20 tracks. The first thing it does is analyze the waveforms, which takes about 5-10 minutes, tops. After that I have never experienced any slowdown with re-drawing waveforms.
I understand that it isn’t going to be instantaneous. However, when FCP7 was rendering waveforms much faster than FCPX, there seems to me to be a problem.
I just set up a 2-disc raid 0 that I benchmarked to nearly 300 MB/s read/write…I’ll give that a shot and see how it does. Before I was using single drives over esata that benched about 80-90 MB/s. Not screaming fast, but should be fast enough for most work.
One other thing, I have noticed a big difference between waveforms that are read from aiff files and those red from the audio embedded in ProRes media. The embedded audio seems to take much longer, while the standalone files read much faster. I suppose that’s to be expected.
