1/30 and lower
I dunno if its me but i CANT seem to get lower then 1/30 shutter in the "new" manual mode. The wheel only turns soo far.... Is there a way to set the camera lower then 1/30 shutter?

Ozan,
I am not an expert, but it seems to me that if the camera records at 30fps, then it would follow that it needs to shoot at 1/30 so that one frame can be coded 30 in one second. Any lower and you will be getting duplicates and partials, I guess. |
Rick is right. At 30 frames per second, the exposure of each frame cannot be longer than 1/30th of a second. The camera could simulate a longer exposure by adding in previous frames, but you can also do that in post.
One way to accomplish an interframe blur in most any NLE would be to duplicate your timeline, slide one of the timelines to the right by one frame, and then adjust the opacity of the top layer to taste. Various NLEs will likely have more specific motion blur effects and plugins; the above method is generic. |

hmmm, dats weird. I remember before the new firmware update.... i was able to hit lower then 1/30... The image would be super grainy but it totally helped in low light. |
Yes, in non-manual mode or in the old firmware, shutter would read very slow settings in very dark shooting situations, slower than 1/30th, but they were never actually used. When it said 1/15th sec shutter it was actually just using iso 6400 etc. thats why it looked extra noisy when the shutter number went down below 30. if it was actually using slower shutters than 1/30th, it would get blurrier and choppier, not noisier. now you can just set your iso super high if you want, if i recall they go pretty high above 3200 if you use manual mode and you have extended iso modes turned on.

Bill, if the camera slows it's framerate to 15fps to get 1/15, then it's not really shooting slower than its framerate, is it? ;)

No video camera truly shoots at a lower shutter than the inverse of its frame rate. Most video cameras have what's called "frame accumulation mode", where you can stipulate the number of frames to pile on top of each other. It's interesting that there aren't too many threads on dvinfo.net about this topic. Here's one:
http://www.dvinfo.net/conf/sony-xdca...lp-please.html You see the standard kinds of slow shutter speed videos, the same way you see them for still cameras: nighttime shots of stationary objects, fireworks, smeary celestial bodies and blurred babbling brooks/waterfalls with stationary backgrounds (my favorite). But whats the advantage of such a video over a still shot? |
