tugela Posted March 28, 2016 Share Posted March 28, 2016 It can be changed on my NX1. What are you talking about? Quote Link to comment Share on other sites More sharing options...
Beritar Posted March 28, 2016 Share Posted March 28, 2016 Use "M", "C1" or "C2" mode for the control of the Shutter speed. Quote Link to comment Share on other sites More sharing options...

AaronL Posted March 28, 2016 Share Posted March 28, 2016 for photography or video? you cannot set it to 1/10 for video Quote Link to comment Share on other sites More sharing options...

sidi Posted March 28, 2016 Share Posted March 28, 2016 Time lapse maybe if you can set it to 10 fps plus external audio recorder. Quote Link to comment Share on other sites More sharing options...
Beritar Posted March 28, 2016 Share Posted March 28, 2016 This is possible on the Gh4 and the camera is not so expensive. Quote Link to comment Share on other sites More sharing options...
SMGJohn Posted March 28, 2016 Share Posted March 28, 2016 I think the OP just wants to remove the shutter limit in video mode which can only go to 1/30, Samsung most likely put it there to prevent people who do not know what they are doing from go below the recommended shutter angle for video. Camera should do just fine if you remove the limit as there is no restriction for video mode regarding shutter speed, its just the amount of times the shutter closes every second, video mode can function even if the shutter is set to BULP mode on some cameras. Low shutter speeds in video mode can help create cool blurry art shots which is probably what the OP is looking for.

RieGo Posted March 28, 2016 Share Posted March 28, 2016 yeah, i didn't know that this is available on average cameras. this is new to me. 1/30 is no hardcoded limit, as it's 1/25 (i think) on 24p and pal 25p, so it's linked to video framerate Quote Link to comment Share on other sites More sharing options...
MountneerMan Posted March 28, 2016 Share Posted March 28, 2016 I have never heard of setting the shutter speed to lower than your fps. How does this work? does the camera split and combine the data from each 1/10 of a second for multiple frames? Quote Link to comment Share on other sites More sharing options...
AaronL Posted March 28, 2016 Share Posted March 28, 2016 I have also never heard of this, i am guessing it would give you that classic first person "drunk" style ? ... might be completely wrong, but would adding motion blur do much the same thing?

It just exposes each frames multi times and of course it gets very blurry the lower the shutter speed. Here is an example of what I am speaking of, its very widely used believe it or not: Quote Link to comment Share on other sites More sharing options...

Do you know exactly what is happening in camera when you have a longer shutter speed than frame rate? I mean it is obviously impossible to expose the sensor more than once at a time so the camera must be doing some math internally witch makes me think that there is no reason you cannot achieve the same results in post. I suppose the camera is likely using the raw sensor data where when done in post it would be using the compressed codec data. Quote Link to comment Share on other sites More sharing options...

As far as I know it just keeps the shutter open for longer than normally, I said multiple times but I meant for longer period of time. Its the same principle as for photo but in this case its for video and the result is shown in the video, replicating it in post might be hard and time consuming though.

Other cameras may give a number "slower", but it is not real since the sensor is always being exposed once the shutter speed hits the frame rate. It physically impossible for it to be exposed for any longer. 12 hours ago, SMGJohn said: I think the OP just wants to remove the shutter limit in video mode which can only go to 1/30, Samsung most likely put it there to prevent people who do not know what they are doing from go below the recommended shutter angle for video.

Just offset duplicate copies of the clip by one frame and set the transparency to 50% (or whatever fraction you are using to simulate a longer exposure). Shoot with the shutter speed set at whatever the frame rate was and you are good to go. It's pretty simple. Quote Link to comment Share on other sites More sharing options...
Geoff CB Posted March 29, 2016 Share Posted March 29, 2016 Unlocked shutter would be a great thing. Mainly because I want 1/48 as an option in 24p for a true 180 shutter. 1/50 is close but not the same. Pavel Mašek 1 Quote Link to comment Share on other sites More sharing options...

Like I said, if you want to smoothen out motion in clips separately from what is not moving, good luck. Quote Link to comment Share on other sites More sharing options...

Like I said, if you want to smoothen out motion in clips separately from what is not moving, good luck. I understand the principles of shutter speed (and traditional shutter angle). What the video doesn't address is the ability for some cameras to "replicate" a slower shutter speed than frame rate. eg. 1/10 sec x 24fps = 2.4sec worth of exposure every second = physically impossible 10 hours ago, tugela said: Not really.

I did a liltle more research and my assumption and what you mention appears to be correct in that if you want to do this its best to just do it in post with the method mentioned above or similar. 2 hours ago, Geoff CB said: Unlocked shutter would be a great thing.

Has anyone tried to force 1/48 of a second using the "st" command? Quote Link to comment Share on other sites More sharing options...
