Hi,
Simple "hack" to enable silent shooting in single mode (not CH/CN):
[root@drime5 ~]£ st cap capdtm getusr 117
UserData is ADJUSTSHUTTERTYPE_MECHA (0x750000)
[root@drime5 ~]£ st cap capdtm setusr 117 0x00750001
UserData is set
[root@drime5 ~]£ st cap capdtm getusr 117
UserData is ADJUSTSHUTTERTYPE_ROLLING (0x750001)
ROLLING is full electronic shutter
Now, why Samsung did not enable this in the menu I have no idea... It's fully working in full resolution JPEGs and SRW files.
I have not time to test whether image quality suffers, but it looks OK to me
Could someone check if it works with NX1 as well?
Cheers and have fun,
Otto
Any idea why changing the video parameters don't seem to take effect?
things like:
#MOVIE_GAMMA_CONTROL_STANDARD (0x760000)
#MOVIE_GAMMA_CONTROL_GAMMA_V (0x760001)
#MOVIE_GAMMA_CONTROL_GAMMA_D (0x760002)
st cap capdtm setusr 118 0x00760002
#VIDEOSTABILIZER 95
st cap capdtm setusr 95 0x005F0001
#MOVIEFRAMERATE_FPS12_5 (0x370000)
#MOVIEFRAMERATE_FPS15 (0x370001)
#MOVIEFRAMERATE_FPS24 (0x370002)
#MOVIEFRAMERATE_FPS25 (0x370003)
#MOVIEFRAMERATE_FPS30 (0x370004)
#MOVIEFRAMERATE_FPS50 (0x370005)
#MOVIEFRAMERATE_FPS60 (0x370006)
#MOVIEFRAMERATE_FPS100 (0x370007)
#MOVIEFRAMERATE_FPS120 (0x370008)
st cap capdtm setusr 55 0x00370008
The settings do take effect but you have to be in the right area as they do not change the userdata that's is displayed in menus, so if you press the menu button or switch off and on again then the setting is lost.
A good example of this is the VIDEOSTABILIZER
if you type:
st cap capdtm setusr 88 0x00580001
This will turn the video stabilizer option to on, if you then type:
st cap capdtm getusr 88
it will return confirmation that the VIDEOSTABIIZER has been set to VIDEOSTABILIZER_ON 0x00580001
However as you are probably not in the video preview or movie recording part of the system then it doesn't immediately take effect.
The problem is if you do video preview, the camera is preset to obtain the VIDEOSTABILZER setting from the userdata (what is set in the menus) and not what you have just set. This means that it just overwrites what you have just done and resets back to an OFF state (or whatever is configured in the menu).
The only way I have found to get it to work is to put the camera manually into video preview (haven't been able to find an internal option that will do it for you yet)
Once you are in video preview do the st cap capdtm setusr 88 0x00580001
This doesn't immediately put the camera into DIS mode but if you now hit the record button it will start recording with DIS turned on (assuming you don't have a setting like 1080p 120fps set in movie resolution which does not allow DIS)
So now you can see the issue that we have with a lot of these commands, some work instantly, some have to be done after one of the other settings have been set and some just don't seem to do anything.
I suspect that will be the same for the rest of the movie settings you listed.
MOVIEFRAMERATE is linked to the MOVIESIZE, so if you have a MOVIESIZE that doesn't support a MOVIEFRAMERATE of 120fps then it will not change, also if you change MOVIESIZE it will automatically change MOVIEFRAMERATE to it's default setting for the MOVIESIZE. And again you have to be in video preview mode or record. You are better off using the equivalent sys_param command.
