Why cant the Nokia n900 record at 100 FPS like other phones?
 
The LG KU990 Viewty records at 100 FPS and thats years old. Would it be so hard to allow the N900 to record at 100 FPS too?

Why would you want that?

or atleast at the same fps as the iphone 3gs

Why? 240 × 320 @ 100fps? What would you want to record at that small of a resolution? According to its specs LG KU990 VGA 640x480 is only at 30fps.

The N900 specs is shown to have 25fps at 848 × 480 which is about 1/4 more pixels (which is a lot -- for only a 5 frame loss). So I don't know if the camera is "locked" to a certain speed on the n900, but if it isn't is should easily be able to handle 320x240 @ well over 100fps...

In the video review it says 100 FPS: http://reviews.cnet.co.uk/mobiles/0,...92601-1,00.htm
Skip to 1 min 18 seconds.

100 FPS is very good for slow motion, watching things back in slow motion, such as playing a sport. This can really help your technique and improve your performance.

I play Badminton and i would find it very useful if somebody could record me at 100 FPS. I could then watch it back and see exactly how i moved my arm, and wrist all in slow motion.

Not sure about what cnet might be smoking -- but according to the actual manufacture (I assume they know the truth <g>):
http://www.lge.com/products/model/detail/ku990.jhtml
and
http://viewty.lgmobile.com/uk/

VGA (640x480) is only at 30FPS. QVGA (320x200) is at 120fps.

Now your use case is actually a pretty good reason. I can see you using it for that purpose.

The only point I was trying to make is if you can pump 407040 pixels at 25 fps on the n900 then "technically" you can pump 76800 pixels at about 132fps on the n900 at that same qvga (320x200) resolution. Does that make sense. I don't know if it is easy to do so, but hardware wise it should be capable.

The Viewty is a imaging-oriented mobile phone. Its primary purpose actually happens to be its still and video abilities. If Nokia were going for the same goals within the N900, then you would have seen it marketed in the same light. Nokia isn't.

So the question shouldn't be why doesn't the N900 do this, but what business sense would it make for it to do this in light of another niche product not in its class of device that does it?

In theory, the Viewty was a good idea, but the quality of the video wasn't very good. I'd like to see a bump in fps, too, but not at a sacrifice of image quality. Maybe HD will change that down the road. I've noticed Samsung hasn't tried to implement the high fps in its high end, and probably for good reason. Without a suitable capture resolution, high fps is useless.

Yeah, they have Chris - my i8910 has 120fps slow-mo in half/quarter/8th speeds.

Its nice to have from time-to-time, I won't miss it much though.

There is nothing in the hardware of the N900 that prevents this being implemented, it largely the same as the i8910. The problem will be Nokia's software implementation, they have been very slow in relation to their competition to add things like panoramic mode and face/blink/smile recognition.

NZtechFreak!! Hello, my fellow Freak. Not surprised at all to see you here. :P I wasn't that satisfied with the video quality at that rate, but Nokia is behind in that respect. I think 2010 will be Nokia's year for imaging, though. Lots of stuff coming down the pipe.

if you really want to have good slo-mo video, buy dedicated camera that can do it!

there is no options, really

and the reason why:

i'd say the fonts are about same size in both pictures @ real life.

yeah but have you ever seen the horrible video qaulity on 3gs. no thank you. my n95 does better video.
