STEPS TO REPRODUCE
1. Open the application.
2. Put a video into the project bin.
3. Drag the video onto one of the tracks.
4. Apply Fade In (or Fade Out) to the clip. 
5. Set the Fade effect's duration to its maximum value.
6. Resize the clip to half its initial length.
7. Resize the clip back to its initial length.

OBSERVED RESULT
1. Fade Out's start does not match the expected duration and the clip does not completely fade out.
2. Fade In never makes the clip fully opaque.

EXPECTED RESULT
1. Fade Out's start matches the shown duration and the clip becomes completely black/transparent at the end.
2. Fade In makes the clip fully opaque at the end.
