I did a study on my 700D vs ASI224MC about the number of frames you need to stack to remove the noise and posted the results here, you really need to stack about 2000 frames to reduce the noise to acceptable levels.

If you are still not convinced, just capture the video for 3 minutes and stack a smaller section of it in AS!3 using the "Limit frames" tool and compare the two, stacking more frames means you can sharpen more without introducing more noise.

With my ASI462MC I get 5000 frames in 1min
