Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I think that if the high-speed frames came out blurry, you might have to increase the ISO Speed setting a bit. High-speed frames need a high ISO Speed.
Otherwise, if your software already plays back frame-by-frame, it's all that's needed.
And, other settings (aperture and shutter speed) they should be set for a good picture, by and large. If the picture is blurry now, or each frame is blurry now, you need to set the ISO slightly faster, and make sure the other two settings are adequate for aperture and shutter speed.
