One problem that contributes to diminished video quality is the image is not the best size for encoding Flash. Both the horizontal and vertical dimensions should be evenly divisible by 16 (640×360 for instance). Take my word for this. There’s a long-winded technical explanation. Obviously, increasing the data rate will increase the quality. At the image size you’re using your data rate should be at least 500 to 700kbps. As for cropping, in Flash Encoder > Settings > Crop and Resize use the controls in the Crop section. You’ll notice a line descends (and rises) as you adjust the controls. If you have black on the sides, crop in that direction, too. Crop to a pixel or two past the black (keep the numbers even top and bottom) and Flash Encoder will take care of scaling the image. Also, be sure to use the On2 VP6 codec (In Settings > Video). Hope this helps.
