You can use a YouTube video. When you’re editing your page look in the hero section, there is a field for a YouTube URL. You can enter the URL to your video there.
I don’t know if it’s possible to queue it to a certain spot or not. I’ve noticed in watching a YouTube video embedded on another site and then clicking the YouTube logo to go to YouTube itself, that the URL is a bit different and includes the time in the video where I made the click.
You might try looking in Google to see if you can determine how to set that up in the URL. I can’t promise that the video will start from that point, but it’s worth a try.
If that doesn’t do it, you’ll need to upload a video that is cut to the right spot from the start.
Let me know what you turn up,
Bill
