Interval recording and slow shutter
 
Has anyone dug into the menus and found these features on the FS100?

They're not listed on the official Sony pages I've found, but I've seen mention of the Slow Shutter (SLS) on other sites. Interval shoot mode?

Technically the FS100 does not have "slow shutter" and "interval record" modes like the XDCAM cameras. However, both of those things can still be accomplished with the camera.

The shutter speed can be set as slow as 1/3 second, so technically that is the same as having a slow shutter with 8 frames of accumulation when shooting 24P.

S&Q Motion can be set to 1 fps, so that is equivalent to using interval recording with 1 frame per second capturing. So, if you can get by with a maximum interval of 1 frame per second, then you do have a quasi time-lapse mode.

Thanks Doug - great info. Can we extrapolate from this, that 1fps recordings occupy the same amount of storage space as 25fps recordings? If wishing to capture the setup of an exhibition space, for example (a day's build), I'd need the 10 hour 128 GB SSD? Or is it a little more space efficient than that?

Or maybe one keeps a DSLR body specifically to do stills based timelapse! :-)

Matt,

I'm not sure if I understand what you are asking, so please excuse me if I don't answer the right question.

If you set up the camera to record 1 fps in a 25P recording mode, you will only be capturing 1/25 as much raw footage as you would at 25 fps. So, for example, if you leave the camera setup for 10 hours shooting at 1 fps, the total length of the footage you capture (when played back) would be 24 minutes. That's all the space you would need on the SD card or the attached SSD. You could easily fit that on an 8GB card.

I have a handy time-lapse calculator on Vortex Media's website, and there's also a link there to a friend's iPhone app that does the same thing.
Go to the tab that says "Software" and choose the link that says "Free online Timelapse calculator"

Well done, you've got the jist!

IIRC, some systems 'pad' slow fps recordings or just throw in a few flags, others (like the EX1) just record the data, so good to know long '1 fps' records are done without padding.

Sad not to see SLS and timelapse on the FS100, but 'praemonitus, praemunitus' and all that. There's probably an FCP filter by now that would do much the same thing as an accumulation shutter for that 'blurry trail' look in timelapse sequences.

BTW, just caught up with your work on the FS100 Vimeo channel - beautiful!

Does it have frame recording like the EX1/3? I use that for stop motion. EX you can set it up to record a number of frames with one button press.

Nope. That's one of the dozens of features you give up when you drop from an F3 to the FS100.

Ok, thanks Doug.
