Possibly, you have set your 'work area' in Premiere so that it does not meet the end of the sequence. i.e. five seconds short. If you export 'work area' then you rfinal movie will be short.

Chek it. Zoom in on your sequence and chekc th estart and end and make sure your work areas lines up. Of course, you can always export the entire sequence to get around this.

Similarly in Encore. the only edit possible in v1 and v1.5 is the crop the start or end of your timeline. Maybe you did that by mistake.

just trying to think about what might have gone wrong.
