All you need to remove is the quiet space before you start talking and after you finish. You do not need a separate editing app.
That’s the whole edit. Trim the beginning. Trim the end. Watch it once. Done. If you feel like the video needs a lot more editing, it is usually easier to record a cleaner take.
SAME TRIMMED FILE, FOUR PLACES
Before you post, double-check that you are signed into the dealership account, not your personal account.
Keep the trimmed file on your phone. The same video works on all four, so post it to one platform, then work through the others. Never add a second caption layer on top of captions you already added into the video.
