I usually set markers for the audio by pressing the . key on the num pad, then hitting the * key on the num pad for every beat.
Then I select the layer with the audio, press LL to reveal the waveform, and check my markers against the waveform. It only takes a few minutes. Your CTI shouldn't be skipping frames using this preview method but if it does you should still get accurate markers.
Here's the problem with that - the CTI jumps 10 frames at a time no matter what preview method I use - waveform showing or not. Since markers are only dropped at the CTI's location, I can only drop markers at points that are 10 frames apart, and unfortunately, the waveform isn't a good one for determining the beat.
I guess I'm really trying to find out if this is a norm for AE, and it seems from your reply that it isn't. Now if I can just figure out why it's jumping.
Do you have OpenGL enabled in the prefs? How about the "use hardware acceleration" pref for panels? If so, try disabling both and see if it makes a difference. You look like you may be using a PC. What's the status of your display drivers? Most recent? Bug free?
Yes, OpenGL is enabled, as well as hardware acceleration. Here are my system specs...
Asus P6X58D Premium
Core i7 950
nVidia Quadro 4000 - driver version 267.24
Windows 7 Premium 64bit
System Drive - WD Caviar Black 500GB SATA
2nd Drive(Pagefile, Previews) - WD Velociraptor 10K drive(600GB)
Media Drive - 1GB RAID5 (4 - WD Caviar Black 500GB drive)
Matrox MX02 Mini
CS5 Production Premium
I should mention that I have Nucleo Pro 3 running, but this happens as well with previews being handled by NP3, and with it disabled. The current driver from nVIDIA is 270.61. I guess I can try it out, but I don't like getting too far ahead of what Adobe has cleared.
You might try trashing your preferences files. If you're only getting CTI movement every 10 frames maybe something got fouled up there.
Trashing them didn't help. NVIDIA driver is next.
...OpenGL is enabled, as well as hardware acceleration.
If you're sure you're not Shift-RAM Previewing -- which does indeed skip a number of frames that you specify -- turn off Open GL and hardware acceleration, and see if that helps.
