Speeding up audio/video

So I recorded a screen recording that has audio and video and I would like to speed it up, but the audio only trims when I try.

Selecting the clip and doing cmd+j and entering 400 (the % speed I want) makes the video speed up, but leaves the audio out of sync and trimmed (not sped up at all)

Unlinking the clips and doing cmd+j tells me a conflict occured in the trim operation, if I move the clip away and try again it trims it, but does not speed it up.

Thanks to anyone that can help.

See if this helps:

Also check when you make a speed adjustment that it will not impact on another track or clips in the Timeline.

This is the usual reason for the "conflict occurred" warning.

My only suggestion would be to make absolutely certain that you converted the screen recording to the proper format for working in FCE (FCE doesn't work with most formats created by screen recording software). That means matching the clip to the Sequence settings in your FCE project, including frame rate, pixel dimensions and AIFF audio at 48khz, 16 bit.
