Why Premiere Elements exported project is "jumpy"?
Make sure you turn each clip's setting to deinterlace on. If Elements has flicker removal, turn that on as well. Make sure you scale your clips to the right size. But if your source is 10 FPS, converting it to 29.97 is not going to create extra frames, unless you use a plugin or effect like frame blending or twistler. You will simply be playing back 10 FPS at 29.97, meaning each original frame will appear for (approximately) 3 frames at 29.97. 10 FPS is jumpy. 24 was set as the standard a century ago, after 18 FPS had been used for some time and was ruled too hard to watch (flicker). Thus why all the old sports movies look like they run fast... because they play them back at 24. Hope that helps.
