I have been selecting clips from my timeline in order to copy and past them to a new sequence. Once I paste a clip to the new sequence, the length of the clip changes. The original length of the clip is: 01:00:10:16, but the new clip is 01:00:10:12. The timing for these clips is very important. Any ideas as to what could be going wrong? I'm just copying and pasting - don't know why the clip length would change.
