Why when i shoot 30f or 24f i feel like the footage is Strobing, Flashes
 

do you know what i mean?

its like strobe light hits the screen, not clear like film, does it have to do with my shutter speed or the frame rate?

If I shift the camera from 60i to 24f, it does look as you describe. I don't know if it's just my not being used to the cadence of 24f, the way that the Canon displays the 24f image on the LCD and viewfiender or both. Viewed in the edit suite and in the finished product, 24f looks fine and no strobing is evident.

I wouldn't worry about it. I think it's most evident when shifting from 60i to 24f. I think it takes my eyes a while to get used to it, but like everything else about me my eyes are old and slow.

I get that effect when I use a fast shutter speed. I get the best results when I use a shutter speed of 1/60 for 30f. I think using a shutter speed faster than half the frame rate leads to the strobe effect.

Another revalation today
 

a day ago i was shooting a Birthday in a hall , i was experiencing something rather weired, i was on sd 3:4,16:9 ratio and HDV at 60i , and i was under flourecent light, and guess what i was getting? real flashes strobing at 1/30 shutter Speed up untill 1/100 it stopped, one step up on the shutter speed the flashes strobe faster, unbelievable, when i went out it didn't strobe much because the light is a regular bulb , no problem either kind of speed.

what is the matter with the camera.? do u guys get the same thing?

share with me.

The strobing on 24 and 30p, is it on the LCD or when you view the footage after? For me 25p looks crappy on the lcd but can look great on a HDTV.

Can you post examples of the footage and we will try and figure it out. Doesn't sound like a camera fault.

Unlikely. Could be weird or cheap lights, or something weird with the camera.

A 1/60 shutter should work in complete sync with the US power grid since it's 60Hz or cycles. Increasing the shutter speed to 1/100 would likely make things worse since 100 is not divisible by 60. 1/30 might be a better option, but there are other potential issues.

So i guess i need to set it up to 50Hz because i'm in Europe with an NTSC camera.?

how do i set it up?

If you are shooting NTSC 60i in Europe, set your shutter speed to 1/100 to eliminate catching cycling from light sources.

May be i could play around with the Clear Scan Function..?

anyway i tried but it starts from 60.01hz anyway i think i'll upgrade it to Pal and i won't have any problems.
