Adding Composite Input (Capacitor Question)

[kf4rca]

There is something wrong with your buffer detail. The emitter should be negative with respect to the collector if it is an NPN transistor. That circuit would call for a PNP transistor. You really need TWO stages of amplification. NOW, you can get amplification out of one stage but it will be INVERTED which is NO GOOD. SO, you really need two stages. The first inverts (with gain) and the second re-inverts. SO, now you are "right side up." Remember, in video, polarity matters.
