Step 1: Click on Edit > Media.
Step 2: Then select "Media properties".
Step 3: Set trim "from". This tells the video when to start.
For example, if your video is 10 seconds long and you set the start offset to 4 seconds, the video will start playing from the 4th second.
You will also see the option to check the trim "to", which shows how long the video will play after setting the start offset.
If needed, it will loop to fill the sentence.
At the top, you’ll see the full length of your media (shown as "Duration") to help you pick the right starting point.
Play the video from the side to make sure it starts at the right time. Once satisfied, click proceed and then save changes!
