streaming and time lapse in HD
on Jul 27, 2010 at 1:42:10 am

I am trying to put together a long term project with the final products being both a live web-stream and (later) a time lapse video. Here is what I envision:
A weather protected HD video cam (with AC power supplied) outputting an HD-SDI signal over about 100' to a PC where:
1. the 16:9 video is converted to an SD signal, encoded and streamed by Windows Media, while,
2. once every hour of every daylit day for 9-12 months, an HD image is captured to disk (sequential jpg or RAW file?). Then,
3. after the project duration, the stored stills will be imported into FCP to make an HD time lapse of the project.
I have searched but have yet to find product(s) to do this and appreciate any input.
Thank you.

We have done some successful time lapse in the past, using the AXIS brand webcams, which contain a built-in server that will collect and send the stills to a remote site. Our experience was SD, but high quality SD jpegs. They probalby now offer an HD version, try checking them out. There was also an outfit called something like Colorado Video; their specialty was remote webcams in remote palces, solar-powered, and using a modded motorola cell phone to transmit their still grabs. Typical use for these was remote mountail passes to check for snow drifts or landslides, as well as ermote grass landing fields that pilots could check visually before they took off.

Pelco is probably still your best bet for the secure camera container: they offer climate-controlled versions for extremes of temperature and humidity, as well as wiper blade options.

Interrupted power is going to getcha; spend what you have to, to keep the power supply steady, and always archive the footage every day.

Hi there

People saying they don't make mistake's often make nothing at all!
