3ds max animation rendering?

My rendered images always need some type of Photoshop work before they can be released to the client. This is why we very seldom ever render animations- we just havent been able to improve the final animation frames with a post production process. Is there a way to do this? I've tried rendering .tga's and sending them through Photoshop then embling them in Video Post. This is time consuming and impossible to get condsistency between frames. thanks Joe
