I have a video asset that is 1:57 long. When I import it to AE, in Project window it suddenly shows that video is only 1:49;15f long! Why does it happen and how can I get my extra 8 seconds back?

Those 8 hidden seconds contain sound that I need to work with.

UPD: here's all the data about this video asset (taken with MediaInfo software):

  • @Mulvya I don't know how to check it, could you please tell me? It seems that my video asset did not just changed its frame rate, but it lacks some seconds which were not empty

  • Check using mediainfo. Use View -> Text mode.

Try converting the video to Quicktime ProRes format, or another format that doesn't have intra-frame compression before you import it into After Effects.
