I am about to start production on my first indie film and will be shooting 24p. I understand strobing while panning but I was wondering if camera was stationary and an object such as a car passes at significant speed would this object strobe? or is it strictly the moving of the camera that produces strobing?
 
strobe??? ugg can someone please nelighten me on what exactly that is referring to? is it when the shutter speed and 24p dont sync up?
 
No, it's just that the motion won't be as smooth as real life... just like film. It's nothing to be concerned about.
 
Bro, it's normal for it to strobe.. Do a test.. One at normal "video rate (60)"
, and one at "film rate (24p)" and see which one looks better to you..

Also, watch ANY movie where a CAR passes by the way you are refering to, and you will notice it there too..

BLINK your eyes as quick as you can and move your hand in front of your face.. Think of EACH time you blink as a FRAME.. Think of BLINKING as 24 FRAMES, but keeping your eyes WIDE OPEN and doing the same thing, is like 60 (video)..

It's all about information.. Or the LACK OF in this instance..

In 24 frames, there are spaces of information that are not there with objects moving at a certain speed, so therefore you see the "strobe effect".
In video there are 60 frames of information in 1 second, so it's almost 3x as much information, therefore NO STROBE.

Make any sense?
 
well... ok. that's just too obvious tho. and why is it called strobing? i was thinking it had something to do with a fluctuating exposure.
 
Read Barry's "DVX Book," it has an entire chapter explaining strobing and how to minimize it.

However, once you come to appreciate the "film look" you'll love strobing, and you'll start to notice just how much of it is in movies and TV shows. Especially after you read Barry's book and learn the tricks that filmmakers use to minimize it.
 
thanks guys I know what strobing is and why it occurrs just didn't know if it was limited to camera movement. I appreciate the help.
 
If you knew what strobing was and how it occured you probably wouldn't have asked the question.. :)

nothing to do with exposure.. strobing is just the way it's explained.. like a STROBE LIGHT gives movement a choppy look.. (thanks Barry, your plug is on the next page)

well thats what threw me off. I know 24p (and 30p for that matter) will give a certain effect... but the name strobing made me believe it was the effect of the exposure fluctuating. Kind of like what you see with really overcranked film cameras, with fluorescent lights. the light will appear to dim and bright rapidly. i thought that was the effect being referred to.
 
I'm still not to the point yet to where I fully appreciate "strobing" in my videos. I think that the PAL version of the DVX creates a much more impressive look with it's 25P mode. I'm sure I'll come to love the strobing, but as for now, I'm confused as to how it enhances the feel or quality of the final product.
 
When you know how do deal with "strobing" cinematically, you will.. There are rules. Get Barry's HVX USER book.. It will explain them..

I've been in the business for 12 years, and learned alot with his book.. it doesn't just tell you how things work, it tells you how to MAKE things work PROPERLY and understand how you made them work.
