Popo - Those Casios aren't cheap to buy new - so you might look at a used device that does those things - as in the Fuji HS10. These are around at modest second-hand prices, as they don't work at all well as 'snaps' cameras in Auto or Program. However, in Priorities or Manual, the Fujinon lens - 30x / 720mm-equiv, can get quite neat results, particularly in low light, with its 10Mpix BSI-CMOS sensor. High-ISO, low-light, is oddly good for a P&S.
The HS10 does more 'slo-mo' functions than the later HS20/30 - perhaps because those are on the awkward 16Mpix EXR CMOS sensors. It has:
1,000fps / 224 x 64 - postage stamp size playback, novelty only
480fps / 224 x 168 - not much better
240fps / 442 x 332 - usable but not large onscreen
120fps / 640 x 480 - the most usable, quality quite good
60fps / 960 x 720 - good quality, but odd AR. I use added black bars (Avidemux) to get this to 1280 x 720.
The recording is in H264/MOV, 30-second limit, and of course, no audio. If needed, I run my Canon SX10 at the same time, audio-record only, in 44k-stereo, and add-back later in Kdenlive editor.
Edit-PS:- You can 'halve' playback speed with Avidemux - it does that by repeating each frame. The 120fps at 640 x 480 becomes 240fps with playback still at 30fps / 1/8th. Results are quite good. You can re-do at H264 (x264) - or, I usually do a 2-pass conversion to Xvid4. You could also use Std MPEG4.
One "halving" of speed works well, if the original is good quality - doing it twice has rather undesirable results.
Avidemux will also halve the playback speed of HD video - example, if you wanted more than the 30-seconds as above, and in correct AR 1280 x 720, etc.
