I have a small problem with rendering.When i render with default setting my video size is more than 1 GB and i was using only 10 pics, some solids and 1 null object.Can you please tell me what setting is best for rendering so that the size is reasonable and the quality is good enough.Thanks in advance.

As @Oliver-G said above, your final use of the footage will dictate your render settings. But I'm going to explain HOW rendering works, because it's essential knowledge.
Rendering is the process of taking your After Effects comp - a series of instructions of how to process files - and writing every pixel's value to a file (See footnote 1).
The way AE does this is to work from each layer from the bottom-most upwards, calculating expressions, effects on each later, motion etc. Then it computes the next bottom-most layer, laying it over the previously computer layer(s). The final size is not dependant on the complexity of the comp, so a still image will be the same file size (footnote 2) as a full composite with particles, effects, 3D elements etc.
Once this is done, AE then runs the resultant file through a compressor, which is where you choose your codec(s) and compression.
Codec: Every file has three (footnote 3), one for Audio, Video and Container. Think of a codec like the format for that stream in the file - so you can mix and match codecs. This is why
Compression: Set how much data is "thrown away" to achieve a smaller file size. Similarly (footnote 4) to how a
These settings are accessed through the
What you did when exporting is leave everything
Try rendering it as an flv (flash video). Put the quality down to 80-90%, and your video will be much, MUCH smaller in file size with great quality. I can never get small file sizes from avi videos no matter what I do.
