Why does opening the audio part of a video file lead to over a minute of beach balling?

Hello.

We've got very powerful macs, but every time we open the audio portion of a video or the audio waveform needs to display, we get a minute of beach balling. This delay increases.

It seems under a new log in it is less.

What is causing it? How can this be remedied?

Audio is so much smaller than video why should it freeze the system when it can cope with Gb size video files ok?

Any help would be much appreciated,

What video codec are you using and what are the audio parameters of the file - Sample Rate (Aud Rate) and Bit Depth (Aud Format)?

It happens on DV PAL, HDV 1080i and Sony XDCAM 720p25 - so standard audio formats.

Try deleting the "Waveform Cache Files".
