    Sometimes, when I stretch a clip so it plays in slow-motion, Premiere plays it back in jerks and stops. That is, instead of a smooth slow motion, it will play as if it has a velocity curve like a bouncing ball.

    Interestingly enough, this doesn’t happen all of the time, and I haven’t figured out the trick. I’ve played with the combinations of field options, and found that checking “Always deinterlace when speed is below 100%” ( which is the default it seems ) is generally the best option.

    Are there speeds at which slow motion works better than others? Is there some rule of thumb I should go by when stretching a clip so I can guarantee a smooth playback?

    Are you rendering the timeline? It could just be poor real-time playback. It should be smooth (or at least as smooth as your chosen stretched speed allows; 5 fps is not smooth) once rendered.

    Yes, even rendered it does it. I supposed I’ll have to get the time to do a scientific study of it, say, stretching at 95% of orginal, then 90%, then 85%, etc., to see if there is some math to it.

    Here’s a discussion from 2002 which is to say I don’t know whether it’s relevant to PPro.
