Ebayers adding impact to your adverts and increasing your sales with video.

Selling things on Ebay?
It's only customary for online auctions to offer photos of items put up for grabs. But replacing photos with video clips could boost credibility and add detail to your offerings -- and you may reap a nice reward from your efforts.
Why add video? Credibility, for one thing. Still pictures can be compelling and have done a decent job of showing shoppers what they are bidding on. Even so, shoppers understand that dishonest vendors can take advantage of the fact that pictures can be copied from other sources and used to represent items they don't actually have for sale.
Also the ability to demonstrate a product working.
I saw (and heard) this as an example done by a vendor offering a guitar for sale where he actually played the instrument (which was fantastic) - I was really impressed (suffice to say the guitar sold and the buyer and seller were both very happy).

The Tools:
For basic video posting on ebay, all you really need is webcam, an account with a video uploading and hosting service and a good internet connection (preferably broadband).
For uploading/hosting I use The Helloworld suite of products which allows me to upload, encode in different formats, store and stream my video with ease and create the HTML coding needed automatically so I can add this to my Ebay listing. (they even have lessons online to show you how to do this).

Another tip is to add text to your video using one of the free or low cost video editors available.
Use good lighting, in focus and in a quiet place so you can concentrate.
It's good to have written down or memorized what you are going to say on your recording and keep your time short - at a minute or less.
Monitor your video sound and play it back to make sure you have not got a distorted noise before you post it.
If you follow these simple guidelines you'll get a nice recording that will catch the attention of your shoppers and improve your chances of not only getting a sale, but also a higher bid.

So if you are selling something online via Ebay it's well worthwhile using video .
