HV1U frame rate/shutter combo?

Hi all, since I am giving up on using 24p on my shoot the 5th of may (because FCP doesnt support it yet for the v1u, and i dont feel like doing a shoot then "tricking it to work" I am going with the default 1080i 60 (since there is a FCP easy set up for this)

I heard some talk about doubling your shutter number for whatever framerate you are using.

as in, for 24p, use 1/48th for shutter

Someone was complaining about not getting proper slo motion NOT doing this.

anyway, Im I right to believe I should be shooting at a shutter of 120?

thats a little fast I would think?

Maybe I am way off the mark, hey all I wanna do is do my shoot and edit the way I normally do with DV, export it as a quicktime movie, use compressor and use make a DVD5

i am soooo tired of worrying about all this stuff, I just want to concentrate on my content and not numbers

Thanks so much

Keith,

I believe the shutter speed you are looking for (when shooting 60i) is a shutter speed of 60 (I know this doesn't go with the 'double' format, but I'm pretty sure this is the 'standard').

If I'm incorrect (then I've been doing it that way for 3 years with the Z1U), please someone give Keith the right info.

Todd

You don't need to trick FCP, but you will spend a great deal of labor and time involved in the conversion process. And, many of the posted "how-to" are not fully accurate and/or are very poorly written. Best to stay with 60i.

You want a shutter-speed of 1/60th second, not 1/120th second.

The 'normal' shutter speed for 60i (30fps) is 1/60th (180deg) however if you plan on doing slomo or image stabilisation in post a faster shutter speed is a big help.

For example if you plan to slow the footage to 50% in post then you are simulating in post shooting 120i (60fps) and therefore the matching shutter speed would be 1/120th, which is still 180deg at 60fps.
