Duration Problem

Hello. I have a problem about video duration. My video's lenght is "33:25:00" but when i export my video i see "33:18:01". Yes i tried to export "contents" and "in-to-out area" but still i saw "33:18:01" It looks like hitfilm express ignoring my edits.

    @evadarr could you provide a screenshot of the timeline if possible? Although it is probably not related, it would also be useful to know your machine specs.

    Other than that, I would only suggest what you have already tried: make sure your timeline/composition settings are as you expect, and that you are exporting the correct timeline.

    Does the framerate of the timeline match with the framerate of the export? E.g 24 FPS constant doesn't have to be 23.976 Make sure those are 1:1.

    @CNK has likely hit this on the head. The durations you report are the exact error for a 29.97/30 or 23.97/24 framerate mismatch. 

    The difference is 1 frame every ten seconds, or 6 frames/min. 

    A 23.97/24 mismatch is off by 1 second every four minutes. 

    A 29.97/30 mismatch is off by 1 second every five minutes.

    So, for a 33 minute video, I'd expect either 6 or 7 sec drift. We do.
