Can Someone Help With Proper Settings For Fast Action Shots? BMP POSTED at DVinfo.net

Joel Corral · March 17th, 2005, 09:57 AM

hi,

i was out shooting my local surf spot with my HDR-FX1 and i am kinda of confused at what proper settings i should have on the camera to get the least amount of visible interlacing. i have a picture posted if any can look at to see what i mean. the ghosting is so bad. Normally when i shot on my Gl2 i would only have a ghosting appearance if i deinterlaced. please help,

thanks,

joel

settings i used were;

F6.8
0dB
S 180
AWB - outdoors

I don't get it.

This looks like a completely normal interlaced frame to me with the two fields captured 1/60th of a second apart. I suppose you could deinterlace it to 60p and render it to a 1280x720 (60p) video to get 60 descrete frames, or deinterlace it to 30p at 1440x1080. However, if you're doing the latter, you might as well shoot in CF30.

If you decrease the shutter speed (i.e., 1/60th) you'll get more motion blur, and probably a "smoother" looking frame (esp. if you blend the fields afterwards) but you'll lose a lot of sharpness.

I would expect it looks fine on an interlaced monitor - doesn't it?

well, the interlacing look is normal, i may be misleading in what i am trying to say, its really the ghosting that concerns me, i guess that, that is normal then. i know that when i have interlaced DV footage i don't see any ghosting until i have deinterlaced. may be the shutter speed is to high, i guess. so if i shoot at 1/60th i will get more motion blur? and if i go to say a higher speed i will get less? what then, would be the highest shutter speed expectable for fast action shots?

Yes, 1/30th or 1/60th has more motion blur than 1/100th for
example. What is acceptable for a certain shot entirely depends
on the shot, the angles, the motion, the content, lighting etc.

That's why most serious shoots have a high quality production
monitor and do numerous takes and rehersals.

In the end it also comes down to experience of course, so try
to experiment with shutter etc. when you can on such footage
and you should get a better in sight into which setting works
best under which conditions etc. You then should be able to
guess the correct setting when you can't do multiple takes.

What is your final output? As of now, when I deinterlace I see no ghosting. So you shouldn't see any ghosting on the TV when viewing the interlaced clip.
