frame blend will do the job
Frame Blend should indeed work.
If you have the time, you can also try bringing the footage into After Effects at normal speed and applying the Timewarp effect. It does an incredible job at creating frames that didn't exist, and you can get really slow-mo with it. It doesn't always work perfectly, so you will get artifacts sometimes. Keep in mind that this effect is pretty slow, as it does some very complex calculations to create new frames, so you'll need to be able to afford the extra encoding time before trying this one out.
Next time you're out doing nature photography, try shooting a few scenes at a higher frame rate. Anything better than 30fps will help create ultrasmooth slow motion; 60, 90 and 120 frames per second are available on many cameras these days. Higher framer rates often mean a reduction in resolution, though. Some cameras that can shoot 2k at 30fps will only give you 720 at 120fps.
If you're going to explore slow motion as an artistic element in your video productions, just search for the term and you will find many sites dedicated to helping you learn and perfect the craft.
thanks but at this point I'm not working with after effect.
thanks it is a good idea to search for the term as I'm into it now.
In my experience, PP just isn't capable of decent slow motion. You will need After Effects, or a plug-in like Twixtor maybe.
If your camcorder can shoot 60p, import that clip, then right-click it and Modify > Interpret. The frame rate should show up as 59.94, go ahead and change that to 29.97 and then put the clip on the timeline. This should have the result of doubling the length of the clip and providing silky smooth 50% slow motion (without adding Speed Change, leave that at 100%).
Just picked up a new GoPro Hero 3 White, and it has 720p60 and I tried the above and it looks nice! The more expensive GoPros offer 720p120 and that should yield excellent 25% slow motion using the same methods. With the waterproof housing and wide angle lens, you could get right up close to that waterfall!
You can activate Timewarp in premiere.

This works for CS6 and CC
I have after effects installed anyway so this hack may not work on other systems without AFX
It doesn't work properly, though. (Which is probably why it's turned off.) You still need to to go AE for this.
