I know Sony say the 6 and 12 second takes in slo-mo degrade the image more and more, but why should this be so - does anybody know? The three time-lengths all use the same frame rate.

I see the shutter speed is bumped up quite a lot (1/215th slowest - no limit shorter), so it does mean you need good light for filming slo-mo. Also there's a tiny zoom-in when you switch to slo-mo filming, anyone else noticed this (like when you add the extra OIS, but less severe).

I only stick with the 3 sec slowmo because the quality does get noticeably worst with the 12 and 6 sec options.

Most likely it is due to the size of the cameras buffer. In smooth slow motion the info can't be written to card in realtime because there is too much data, so it gets stored in the internal buffer. Because the buffer size cannot change, and the frame rate is the same in all three modes, as the length of recording increases, the resolution decreases to give the same amount of data.

It's similar to how some DSLR's work. With my Pentax K-X, shooting at 12mp, I can shoot a constant burst at about 4.5fps for about 2.5 seconds. If I lower the resolution to 2mp, I can shoot a constant burst for up to 6-7 seconds before the buffer fills up.

Re: Slow Motion Record

I do love the NX5's slo-mo, and have just noticed an interesting fact. When you switch to any of the slo-mo time-frames (3, 6 or 12 secs) the camera always jumps out of the 'Active' Steadyshot mode. I guess this is to retain as much image quality as is possible in these modes.

Re: Slow Motion Record

Active steadyshot uses memory that it needs for the slowmotion buffer ?

Re: Slow Motion Record

The slow motion loses more and more quality the longer you record, so I only ever use the 3 secs.
The default shutter speed of 1/215th sec is the one to use.

Re: Slow Motion Record

In a previous post I was saying how easy it was to do hand-held tracking shots with the NX5 in its slo-mo mode using long telephoto settings. I've used this on wedding films for 'first time successful' shots of flowers, table decorations and so on.

Here's some very short examples pulled straight from the SDHC card (so are mute).

Re: Slow Motion Record

Hi Tom,
I really like the way you have your NX5 set up. I love the sharpness and colours. Would you be prepared to share your profile settings.?
regards
Mike
