Re: Video/Audio out of sync after ...
Hello Final Cut and welcome to the forums.
I'd normally split the clip and apply speed changes that way to the linked clip. But your method disables the link between the video and audio...
From the manual:
"Keep the following points in mind when you use speed keyframes and speed segments:
Any change you make to an individual speed keyframe will alter the segments to the left and the right of the keyframe, but it will leave all other speed segments unchanged.
[b]If maintaining video and audio sync is a priority, select both the video and the (synced) audio and apply constant speed changes only. Applying variable speed settings to a video clip (including speed segments, the Curve buttons in the Change Speed dialogs, and the Curve options in the Change Speed shortcut menu) will break the link to audio items. Audio and video sync is lost when you apply variable speed changes."[/b]
Hope this helps
