Trimming videos not working proper in screencam app.

Expected behavior

I expected the video I screen recorded and wanted to edit via the app be trimmed to the part I needed.

Actual behavior

The trimming doesn't get done. The video trimmed doesnt contain only where I selected. The selection is not precise.

How to reproduce

Using the screencam app, make a screen record.
Click the option menu in the video, and select edit, the editor would pop-up.
Select the part you need trimmed by sliding the bars.
Then save.
The video could be replayed to check if trimmed as wanted.
