Complaint: "Ewwww. It looks so grainy."
It is grainy. Actually, it's pixelated.
Pixelation is an artifact of compression. When you squeeze down the size of a digitized video clip, you have to sacrifice something -- image quality is the first to go.
Video compression finds similarities within individual frames and it also looks for similarities between frames, comparing change over time. Then it removes extraneous material. The more you remove, the smaller the file (but the more "lossy" the picture appears).

The higher quality you have to start with, the better it's going to look at the end.
Blurry or low contrast images compress better than crisp and busy images.
Similar images compresses better than fast action shots (there's more going on).
Fewer colors also reduce file size.
Certain compressors can be used across more computer platforms than others.
At this writing, Media Cleaner Pro is the most popular compression software package.
You can use Media Cleaner Pro or Adobe After Effects to mask and selectively blur out less important parts of your picture, thus reducing file size even more.
