Refactor template matching logic in VideoEditor to utilize transformed frames

Browse Source 
This commit updates the template matching process in the VideoEditor to apply tracking on the already transformed frame, which includes crop, zoom, and rotation adjustments. This change enhances tracking accuracy by ensuring that the template can locate the object in its modified position, while also improving code clarity and performance during video editing sessions.
