what do you mean?
you can take picture every 1min, 5 min and so on and then stitch them into some kind of video file but this would be fast motion movie.
I have camera at work, can do 20,000 frames per second, that could really produce slow motion movies but any Pentax's capabilities are far from it, so what do you mean?

I think he means shoot 720 at 60 FPS, and then edited it in post to be a 30FPS 1/2 speed movie.

Thats what I gather too JinDesu, I have a number of videos shot at 720/60 but i've not tried to slow them to half speed. Shouldn't be a problem

Yes that was my idea, I know that adobe after effects have capabilities to slow down even more by interpolating the missing information so I think that 60fps must be enough for 3 times slowing down. And the question was - is it ok, what about the stabilization, ... compression... is it a fine camera for the job. I have some MF lenses which I would like to use for movies so... the integrated stabilization and 60p movie record is something that drives me to buy K30. But that's only on paper still. Did somebody tried it for real?

The video I posted above says that it is un-stabilized. I don't know about the quality of the compression (I don't own a K-30 yet). There are, however, at least a couple of beautifully done K-30 videos on YouTube (beautiful in spite of YouTube's less-than-perfect conversion/compression process). I posted one of them here (the second one of the two).

I found and posted this very non-artistic K-30 video a few weeks ago. It was shot using an old manual lens (I too have old manual lenses that I would love to use with a K-30 -- or other Pentax DSLR -- someday).

I actually bought it for its ability to do slow motion video at 720p. I received mine today and had a play videoing a cat grooming itself. That wasn't very exciting so i chased it. It works well but i did notice the rolling shutter a fair bit. Will probably work well on a tripod. It was very smooth as you would expect. On my computer screen, it looked a bit pasty like you see with high ISO noise reduction but that is because of the high res computer screen and it not being full HD video. I would bet that it would look great on a TV screen. iMovie gives me the option to help remove rolling shutter effect.

The reason i bought it is because bands have been paying me to do promo videos of their live performances. I did one with the K5 i have linked here.

As you can see it is jumpy due to me making it 50% of the normal speed. My test confirmed that the K30 worked well. I will be doing some new ones in the coming month or two.

Hope this helps

Sorry it's not the beach as i didn't get to see the water on saturday. This is probably slightly out of focus seeing as it doesn't look as sharp as other video i have done. i didn't pay much attention to settings. Just 60fps @720p
