Adjusting shuter speed

[Mark-P]

I am brand new to working with cameras and the HVX. I am going to do a series of shoots in a room that will have the same lighting conditions each time using kinos. The video will consist of someone standing and talking with minimal movement of his arms and body. I will be shooting 720P 24. I want both the person and the background to be in sharp focus.

1.) Is there a general guideline for how to set the shutter speed with my type of shooting conditions? I adjust it and let less or more light in, though I am not sure how this affects other aspects of the video.

Thanks!

Yes - always leave the shutter at 1/48 and never change it for pretty much any purpose unless you have a really, really good reason.

Don't use the shutter to adjust for exposure, you can end up ruining shots because of it. You use the iris, and the ND filters, to adjust exposure. Shutter is pretty much only used for the following reasons:

1) to change the motion rendition of a shot (choppy or blurry)
2) to squeeze in some more light in extreme low-light cases
3) to compensate for some artifact in the image caused by the shutter interacting with a TV screen, computer monitor, or ballasted light source.

If you set the shutter to a high speed under fluorescent lights, you'll get a weird white balance shift happening in your footage (or, with a CMOS camera, you'll get scrolling bars in the footage). In general you should just glue the shutter on 1/48 for 24p, or 1/60 for 60i/60p, and leave it there.

With CMOS cameras, in NTSC territories, just stick it on 1/60 and don't ever change it unless you have a really good reason. 1/48 is a bad idea for CMOS cameras because of the aforementioned lighting complications.

well if you are planning to shoot from moving helicopter /boat/ car . anything that will exaggerate your motion blur . then up it even a little bit more when over cranking and you know it will be slowmo footage where motion blur really sucks. just don,t over do.
