Features of feedBurner; How to reduce Blogger feed size? RSS,blogspot

Google Feedburner distributes not only RSS or atom feeds but also rich media, such as audio or video (distributed via RSS). Feeds like this one provide updates whenever there is new content. FeedBurner makes it easy to receive content updates in popular podcatchers.
RSS (most commonly expanded as Really Simple Syndication) is a family of web feed formats used to publish frequently updated works—such as blog entries in a standardized format. An RSS document (which is called a "feed"or "channel") includes full or summarized text, plus metadata.

Sometime you will find a message like "Your feed filesize is larger than 576K. You need to reduce its size in order for FeedBurner to process it. Tips for controlling feed file size with Blogger can be found in Tech Tips on FeedBurner Forums, our support site" while generating your blog feeds (through FeedBurner).

FeedBurner will not process an original feed from your blog if it is greater than 512K in size and this limitation only applies to the actual size of the feed file itself (it does not include any images or media files).

To get a feed larger than 512K back down to size on Blogger, you need to add a parameter to the address for your original feed's URL.

1. STEP1: Sign into your FeedBurner account.
   http://feedburner.google.com/
   
2. Under "Burn a feed right this instant" area, enter your blog URL and Click on "I am a postmaster" and  "Next".
   
3. Nowfind the feed URL for your blog. It will be two like:
   http//ex-ample.blogspot.com/feeds/posts/default
   http//ex-ample.blogspot.com/feeds/posts/default?alt=rss
   
4. Select one and then click next. Generally you will find the above error message here.
   
5. Here you need to add "?max-results=3".
   
6. Now your feed will be http://ithindi.blogspot.com/feeds/posts/default?max-results=3.
7. Now click on "Next", you will now able to burn your feed.
   
8. http://feeds.feedburner.com/feedburner/sEvC
   (or http://feeds.feedburner.com/blogspot/izcjf)
   
   

Another method is:

• Sign in to your FeedBurner account.
• At the dashboard, click on the feed
• Now click on "Edit feed details" just below your feed name.
• In "Original feed" area, add "?max-results=3" at the last of that feed.
• Again, you can increase the number of results until you reach your maximum point.
