Could Digital Still cameras be hacked to 24p?

Another post, yes my brain is working overtime-


After reading about an 8MP digital camera that shoots 10 or 15 fps,(canon Eos?) it got me thinking.

If you could hack one of these digital cameras and make it shoot 24 fps, then youd have excellent optics, and many times better than HDcam rez.

Even if you went out the firewire route and downsampled to 4:2:0 for example, it could be a pretty nasty piece of machinery.

Ofcourse, you'd have to rig up some portable capturing device, and youd have to shoot sync sound,

Cheers,
Ben Gurvich

I believe the movie mode on the Minolta A1 is 24 frames.

No, it doesn't look like film. :)

It might, but one of the major problems with such camera's
is storage.

I think you're on track - here's my experience...

I own a Fuji s602z, it shoots video at 30P, at NTSC res, (640x480).

The Fuji 602 allows you to shoot as much video as your card can handle, the Max size CF card being 2 Gig, which would give you around 30 mins of footage. (the 602 is not Fat32 compatible, hence the 2 gig limit).

The codec used is MJPEG, compression ratio is around 20:1, (ie the data rate is about 1.1 meg/sec)

From analysing footage I've shot with the s602z, the biggest factor that limits the video quality is the factory set 20:1 MJPEG compression system.

If some clever person could hack the compression ratio in the firmware to give 7:1 or lower, (3 meg/sec), then we would see some superb quality video footage coming from this still camera.

Sony's offer a MPEG-VX Fine that is pretty good rate (not sure exact) as done the new Canon S1.
