Re: Rendered AVI file playing in Slow Motion???

Okay, knowing what you are trying to do gives me some better idea how to address the question. Unfortunately the answer is that you probably aren't going to be able to get what you want.

As the images you are using already have motion blur in them (as you say -"you can see the blur (arms and legs) of movement") changing the speed of playback is always going to look unnatural, because you will invariably get a "still" that shows that blur. There's not really a way to remove it (there are tons of ways to add it). I honestly don't know if frame-blending would address that or not.

Here is something that you might try, and I can't guarantee that it would work, but it's what I would try to do if I had a similar problem.

I would take the sequence you have a 1 second, and time stretch it to something like 1.5 seconds. then I would render that out to a new AVI file making sure I had turned Frame Blending on.

Once done, I would import that clip, and time stretch it by another 50% (make it 3 seconds long), again turn on Frame Blending and render it out.

You are still going to end up with a "slow motion" clip, but this might give you a more natural look to the motion blur. I really don't know.

Changing the frame rate will have exactly the same effect, and there are a lot of complications to having a clip with one frame rate in a comp with another. But essentially, if it moves at 7.5 fps against a background of 30fps, it will be the same slow motion shot.

After a certain point you have to decide that the clip is just not going to work.

BTW, I posted to your thread regarding how to get the "printed" look of the baseball card. That one, at least, I think I might have been able to help with. In this case though, I'd really see if you can get a better piece of video to start with, or you try to stretch it less.
