flv file loses quality when uploaded to server

When i view an flv file inside a swf file it looks fine locally, but when its uploaded text loses it shape. The bitrate for the flv is 1,500+ kbps. Ive attached a picture. The one on the left is local, and the one on the r开发者_运维知识库ight is over the web. Anyone know what might be happening?

You should give some detail on the authoring tools you use and the server you download to. It's difficult to answer your question without some details.

Some raw guesses:

• when you watch locally your flv, it could not be encoded yet but some kind of preview
• the server you download to may use some stream transcoder and not send directly your file
• for some reason the stage size when you play from the server is smaller than when played locally. (if so this thread could be of some help)
