Default Wear out a Digital Shutter? w Time-Lapse ?






On Wed, 11 May 2011, :
If ya don't know, the Canon CHDK (Firmware freeware
hack) supercharges Canon cameras, now DSLRs too!
It's way cool!


I made my first time-lapse attempt with 1,700 640X480 images
using CHDK and my 2009 Canon SX120is 12X. Looking for
freeware to convert them to video I saw a claim that this
will significantly erode the expected shutter life.
Huh?
I thought the sutters were solid state?
He also implied that mechanical shutters would be better
suited.

quoted from a conversation at:
http://www.diyphotography.net/how-to...ource-software

September 8, 2009

If you're using a digital still camera to capture frames
for time lapse, keep in mind that these things have a much
shorter per-frame lifespan than a traditional video camera.
For example, the Canon xxD-series DSLRs have shutters rated
for about 100,000 frames or less, before you have to send
them in for repair (at your expense). At 25 frames per
second on a time lapse movie, this is just over an hour's
worth of time-lapse output. Looking at it another way, if
you used your Canon 40D to "film" an event that generated a
2-minute time lapse, you just chewed up 3% of your shutter's
lifespan.

I wasn't able to dig up any shutter life data on the
point-and-shoots. I suspect they're probably longer, due to
the simpler mechanical action involved - but they're also
likely not "built as tough" as their DSLR bigger brothers.
...much better idea to shoot the thing in video,
then use your favorite video editor (e.g. Windows Movie
Maker, which is free) to speed the playback up the
appropriate percent.

...If your real-time event is something much longer -
flowers growing, building construction, etc. then obviously
you're in the realm of the traditional camera - in...

=============end quotes

Hogwash or not?
If that's not all hogwash, can these "Canon 40D" "facts" be
generalized to other digital shutters?

Thoughts?

BTW, any experienced observations or suggestions for
*freeware* to convert pics to video? I see no rave reviews
in this regard. ...no reviews at all from the usual DL
sites.

No. Mechanical. But a lot simpler than on a SLR so I'd expect it to
last for more cycles - but not forever.

I'd think you'd be better off with a cine camera - even to do time lapse.

Rats! Well if I only get 100K pictures, that does
change my plans. If I got 300k, not so much.
I wonder how I find out?

Seems odd.
That camera takes 30fps 640x480 AVI videos.
That's 108,000 pics/hour. So waz up with that!?
It uses no shutter?

I don't know how that works.
Damnit! Knowledge of ignorance I find so distracting!

Just thinking aloud...How cool it would be if
CHDK (or Canon) could somehow slow that 30 fps
to around 1 fps! ...just dial in the desired fps!

Take it to the CHDK forums - maybe there is a way.

People serious about variable-shutter rate video (which is what this
is) should consider buying cameras dedicated to the task, if they can
afford them. But, you could probably decimated 50 crappy Canon P&S's
and not be at the price level of a video camera capable of what you
want.


You woke up with a turd in your mouth?

25 fps isn't time lapse, more like 1 fps, or even 5 seconds per frame.

I've worn out a couple DSLRs doing time lapse. It might be nice to have
a P&S for some situations but the DSLRs are handy for night shooting,
especially star trails where exposures are longer than the interval you
want without high ISO, and for extra wide angle, DOF perhaps, also you
have more latitude for adjusting exposure in changing light.

VirtualDub works very fast with lots of options for assembling into avi,
then you'll probably want something else to edit with. Note that the
frames need to be perfectly sequential, no gaps. It's a little geeky to
learn but works great.
