Hello, I have completed my project and I want to save it. The saved file tho is not identical to the project, what I mean is in the preview I have trimmed exactly at the points I want each clip to start and end but in the exported file this nano seconds are not matching therefore you can see seconds of video which I had intended to remove and viceversa each clip starts few nano seconds after what I had trimmed - skipping the beginning of each word is spoken.

Why? Please help!

Thanks
