Filming an item to post on eBay is perfect for creating extra interest, especially for more expensive objects where the buyer will want to know more about the item before bidding. Here’s how to do it.

1. Film your item! How you do this is up to you. Then upload the video to your YouTube account in the normal way.
2. Log in to eBay, press “Sell”, and select “Advanced sell”.
3. Choose a category and move on to the “Create your listing” page.
4. When you get to the “Describe the item you’re listing” area, click “HTML” tab.
5. Go to your video on youtube.com, and copy the embed code from the grey box to the right of the video player. Paste this into the HTML box in the eBay listing. Note you can still add all the text for your eBay posting as normal.
6. You can resize the player by editing the object width=”425″ and height=”350″ fields at both the beginning and end of the embedded player code. Make sure that the sizes you choose have the same ratio as the default numbers, so that the video doesn’t get stretched—just multiply the width by 0.8235 to get the height.
7. Complete the posting as usual.
