I have two important questions:

Is the Sony Z5U able to shoot 60fps?

I've been seeing awesome videos online boasting smooth slow motion, and I was wondering if I could achieve this as well using a Sony Z5U - I tried today, but I failed miserably; I cranked the shutter speed to 1500 and set the scan type to 60, which probably isn't 60fps. All the videos I've been seeing are done by DSLRs which reduce to 720p/60fps from 1080p.

I noticed that there is a smooth slow motion feature that cranks the fps to 120 but I think it's just corny that it doesn't shoot for longer than 3 seconds at a time... There has to be a manual way.

My last question: would I be able to achieve this slow motion using the 30p option on the Z5U?

I remember a project back in college where we sped up a song and sang along to it and then brought it back to it's original speed in post production - this is how we ended up with a smooth slow motion with our lips synced perfectly to the lyrics of the song. And, we used a Sony Z1U - I remember doing something with the shutter speed - We had slow motion then, but I guess I just don't understand the concepts of time.

Thank you for any help.

We did a lot of testing of the smooth-slow-motion feature (we use a Sony-V1) for sports but found it unusable.
It's a nice "toy", but the resolution of those clips is less than SD and upscaled in-camera to DV or HDV size plus it has very strong compression artifacts.

The trick in producing slomo-clips with a "normal" camcorder or a DSLR is to record with the highest available framerate (with DSLRs it's 60p, with the Sony Camcorders like the Z5, it's 60i with NTSC models and 50i with PAL models) and then slowing the footage down in post.

Most NLEs do this quite well. If you want to push quality even further, you could use After Effects and it's pixel motion feature or you could use plugins like Twixtor.
Increasing the shutterspeed helps when using those plugins, since higher shutterspeed means less motionblur and that helps with interpolation frames without (or with *less*) interpolation artifacts.

I switched the Z5 over to 60i, which is 30p, right? - i got somewhat of a smooth slow motion, but it wasn't like something i've seen DSLRs do...

Yes, i need to delve deeper into understanding plug-ins... Twixtor would be a good start - do you know where I would be able to get it from?

As for knowing what model i have, a NTSC or PAL model, how would I check?... all this is somewhat foreign to me, including NLES... I don't know what that means, neither...

Thank you very much for your help; I understand a little bit more of what I'm doing thanks to your post.

Thank You,

Fernando

Since you have the Z5U it's NTSC. The PAL model is called Z5E.

[Fernando Bobadilla] "NLES... I don't know what that means"

Sorry, an NLE is simply editing-software.

[Fernando Bobadilla] "60i, which is 30p, right"

Yes and no. "I" means interlaced, "p" progressive.
You maybe want to take a look at those articles:

http://en.wikipedia.org/wiki/Interlaced
http://en.wikipedia.org/wiki/Progressive_video

You can deinterlace 60i video to 30p. The effective vertical resolution will be of course not that good as "real" progressive, but quite good.

[Fernando Bobadilla] " i got somewhat of a smooth slow motion, but it wasn't like something i've seen DSLRs do..."

Just to be clear: If DSLR or HDV - slow-motion in post is always created with plugins or on-board features of your editing software. The quality of your slowmotion depends on the source material and the quality of your software.
