~ I have tried many programs out. As long as it has a chroma key (always mentioned on the box), it will work decently.

~ Easiest and cheapest program to use- Movie Edit Pro 15.

The cost is less than 30 dollars

~ More expensive, higher quality- Pinnacle Studio

~ Lighting counts. If you can shine a lamp on the screen, it will help with editing.

~ Most programs with a chroma key also have an adjustment scale or wheel. This will help with the quality.

~ Consider using a background that has heavy green in it (eg- a field of grass, a forest). Even the lowest quality green screen work will work with this color background.
