Broadcast supermo cameras scan 180 fields per second in standard definition NTSC or 150 fields per second in PAL. HD supermo cameras scan either 120 or 100 frames per second (in 720p, fields in 1080i) depending on the standard. But I've mainly been talking about regular speed cameras slowed down.

By the way. a high shutter speed is just the thing for sports. Otherwise you'd lose the sharpness due to motion.
A fast shutter makes for great still frames but terrible, jerky-looking full-speed footage. That's why you'll rarely see a supermo camera outside of replays.

Still, Newscasting isn't what this camcorder is aimed at...
Oh really? Broadcast stations are a significant market segment for the HD series. The local regional FSN affiliate around here owns an HD100 and is purchasing three HD250s. The camera itself was designed with a form factor that would be familiar to users of high-end ENG camcorders. A JVC representative mentioned in another thread that the 19.7 mbps data rate was chosen specifically so that HDV could be transferred over a microwave link used by newsgathering trucks.

Sorry, I was talking about the 24/25/30 fps only camcorders (HD100, HD101, HD110, HD111). Obviously the 250 (and possibly the 200) is more geared towards TV-work and newsgathering. 25p only like the HD100 is rather difficult for news...

Could you be more specific? Did you export as a TGA sequence or just slowed it down on the clip on the timeline?

Blue ch. noise with 85 filter on exteriors in daylight

Stephen, thanks for the test of the 250's new encoder, but how does the blue channel stand up outside with an 85 filter on?

Thanks
