Unable to Change Original Duration of File/Composition.

[353906451xzd]

Hi I am new to After Effects (Great experience so far) but have an issue dont know where I did wrong and unable to find solution

When I worked on the compostion everything was fine but now when I reopen the project, I am facing 2 problems (observed so far)

1: The file names changed be itself.

12w → w (composition)

12w.png → [12-12]w.png (source file)

2: the original duration of the file/composition geos 0:00:00:01 and that length does not work for me. Max stretch is 9900 which makes it 0:00:03:09. That length also dont work for me plus that huge stretch doesn't make sense. 

I am basically creating whiteboard animation and when I copy mask path to another file (human hand), everything goes wrong. (Needed to mention that I already created some similar animations successfully)

You have imported what appears to be a single image as an image sequence, which is why it has a duration of one frame. Import the image again, and be sure that import as an image sequence is not checked.

To change the composition duration, press Ctrl/Cmnd + K or use Menu/Composition/Composition Settings to open the Composition Settings and change the composition duration. You are trying to change the speed, not the comp duration.

@Rick Gerard Thanks A lot. Replacing the image (without sequence) and copy mask, effect and tranform from previous file solved the issue.
