You don't identify the codec of the AVI footage, and you don't say which version of AE you have. There are a number of things that could affect the render:
  • Running AE 9, but don't have the free upgrade to AE 9.0.2? Get it.
  • Trying to use multiprocessing ("render multiple frames simultaneously"), but you only have 4GB RAM? Turn multiprocessing off.
  • Trying to use Open GL to accelerate rendering? Turn it off.
  • ...and here's the most common source of render woes, pre-CS5 -- using the wrong kind of video footage. Read on:

Dave's Stock Answer #1:

If the footage you imported into AE is any kind of the following -- footage in an HDV acquisition codec, MPEG1, MPEG2, AVCHD, mp4, mts, m2t, H.261 or H.264 -- you need to convert it to a different codec.

These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.

In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems.

I'm a Mac guy, so I like to convert to Quicktime movies in the Animation or PNG codecs; both are lossless. I'll use Apple's Compressor, Adobe Media Encoder or Quicktime Pro to do it.

but when i export widescreen it turned out in 720X576

You simply CAN NOT use any of these letters typical for particular countries (like ś, ź, ż, ę, ó, ń etc.) in the name of file neither in the render directory. So just change the name of file and the render directory if needed and everything should be fine
