Review of Brinno TLC200, TLC200 Pro and webcam timelapse

March 23, 2014

Timelapse photography looks REALLY cool, and thanks to modern technology, its now affordable to most people.

I’ve done a LOT of timelapse photography over the years.  A couple of examples:

The most expensive, and versatile way is to just use a DSLR and an intervalometer.  However if you are going to just turn the images into a HD movie, to be honest a DSLR is overkill!

One option I’ve been using for years is a webcam and a netbook.  It actually works quite well, in that there is never a a serious limit on diskspace and it can run for about 8 hrs on batteries.  I have done a timelapse of a transatlantic flight like this.

Then came some dedicated ‘off the shelf’ timelapse cameras.

tlc vs tlc pro

The Brinno tlc200 pro and tlc 200. Two dedicated timelapse cameras that recently came on the market. The principal advantage they offer over compact cameras with a timelapse capability is a ‘stand alone battery life’ where they will run for days to weeks on the internal battery (4xAA).

The first one I got was the Brinno TLC200.  It worked well enough for me to get two of them, however there is simply no contest when it’s compared to the Brinno TLC 200 pro.  The TLC200 has a relatively narrow angle lens less suited for timelapse (which typically requires wide angle lenses), it is poor at low light levels and cannot be focused.

This review is also available in video form:

The Brinno TLC200 Pro works acceptably well.  The lens is quite wide angle, and can be focused manually.  It will run on batteries (4xAA) for days to weeks (depending on how often you take pictures).  My principal problem is if you are running it off batteries, it’s almost impossible to tell if the batteries are flat, or even if the timelapse is still running.  This point can be disturbing if you are running a timelapse for months, and do not want to move the camera to check it’s still working.  It can be powered off USB, but this obviously requires a USB power cable (micro).  They do sell outdoor enclosures, but generally I wouldn’t recommend them.  They are only compatible with the standard Brinno lens, and when in the enclosure, you lose the ability to power the camera by USB.  

The camera records the movies directly to SD card.  It comes with a 4Gb card, but if you are doing anything sensible, I would recommend at least 16Gb.  The Brinno will also automatically stitch the images together into an *.avi file.  With the netbook, the most reliable method is just to record a series of images, which you can then stitch together yourself using video editing software.  I use Sony Vegas Pro (not recommended if you are starting with video editing, it’s very versatile, but that also means it’s very complicated!), but most video editing software will allow you to stitch together a sequence of images into a video file.

When you compare the video of the TLC 200 Pro side by side with a netbook with a wide angle webcam, the webcam is the clear winner.  The downside is of course you need the netbook to continuously run the timelapse.  For me, I just ran a timelapse like this for over a year, so it basically ‘cost me’ a netbook.  This makes things like the brinno seem cheap.  Having said that, it’s very nice to be able to see, day to day, that the timelapse is still running away happily.  This is an option you just don’t get with the TLC 200 Pro.  However if you want an entirely self contained unit to run outside (with cover from the elements) for a day or two, the Brinno TLC 200 is superb!

If you are going to use a netbook/ notebook, the choice of webcam is critical.  You NEED wide angle.  Personally I would recommend the Genius wideangle webcam.  It gives you EVERYTHING.  Most importantly a very wide field of view, it records in 1280×720 and it has a small compact form factor with good exposure.

Genius wide angle webcam. Most superb performer for timelapse! Recommended without hesitation.

Most definitely recommended on every level!

Prior to this I had used the microsoft HD camera.  This in its native form is relatively narrow angle and less suited for timelapse.  The solution that I eventually came up with was to take the front off the web cam, and add a cheap wide angle lens.

Take the front off your microsoft HD webcam, and you can quite happily add a wide angle lens, which provides quite good results!

This actually worked okay, but for me these microsoft webcams would crash intermittently (randomly from hours to days), which was infuriating if you were taking a long timelapse only to find it ruined by the camera crashing.  This is simply not an issue with the Genius webcam.  The Genius wideangle webcam I have found to be the clear winner everywhere!

Wedneday 27th July (It’s like sex!)

July 28, 2011

It was a disheveled piece of human flotsam that crawled out of the mountains that morning.  I had spent a night fighting a losing battle again sleep, and had, in terms of results, very little to show for it.  I know I thought to myself, look the night might have been one long concatenated mess, but at least I can haul my carcuss down to town and get a thousand calorie breakfast from mcdonalds, and Im sure you will start to get a grip once you have  a full stomach.  Regrettably, by the time I got down to town Mcdonalds had JUST finished breakfast.  The moment was a cross between ‘Falling Down’ and that moment in ‘Evil Dead, Army of Darkness’ in the alternative ending where he oversleeps.  Oh yeah it was one of those ‘the world conspires against me’ type moments.  After a long deep sigh, the eyes snap open with regained focus: time to go on the offense!  Online I soon discovered that the reason the Orion Deepspace Video camera wasn’t working up to expectation is it has an integration function in the menus!  I laughed, when all else fails: READ THE INSTRUCTIONS.  Spent a few hours rendering and uploading what I had.  Now the next problem, that damn screw!  I need a replacement for that damn screw.  Turns out Ridgecrest has a Home Depot, and I figured that was the logical place to try for a bizarre screw.  I was wrong- they had nothing!  Arse, thousands of bux worth of telescope crippled by a tiny screw.  Then it dawned on me, I could just drill and tap a hole myself for any screw I wanted.  Deep in my mind there was a spark, I had a drill and tap and a load of screws that would fit in the car, they were part of the stuff for the airplanes.

Picked up some supplies and headed back up into the mountains, same place at last night.  This time I was more seasoned on that grinding hill though and got up all the way without even a hint of overheating.

Up at the top of mountains, I sorted out firstly the backend of the telescope,

Then the webcam.

Come the test of first light, both performed admirably.  The sky wasn’t still enough for planets, but it was wonderfully clear.

The Deepsky video camera worked as expected! (~500 bux) 🙂

The stripped MS webcam worked admirably (~50 bux) 🙂

The video of the planets shot on by eyepiece projection onto the sensor of the D60 (~900 bux) was okay, but not as good as channeling it straight into a video camera.

The 60d I have to admit is a heinous machine for astro!  I got it primarily as I needed 2 DSLRS to do some of the projects I want to get done on this trip, to work with the 40D.  The 60D just idles circles around the 40D.  I think a lot of it is simply a better sensor.  More pixels, if they are not being used for resolution, mean faster light gathering, and lower noise.  The bottom line is the 60D goes up to iso ~6000, at least 2x what the 40D will do.  The 60D will also do video, which I thought might be useful, although thus far it hasn’t panned out, although this might just be teething troubles with the camera.  Just for an example, crank the ISO up to about 5000 and do a 1min exposure (unguided, bar the telescope tracking) on M51, and this is what you get:

M51, The Whirlpool Galaxy

M51, The Whirlpool Galaxy, 1min exposure, iso 5000, canon 60d

After that, all you need is an intervalometer and deepskystacker.  In many ways it’s such a cheat.  When I was young, I improvised all sorts of devices for the tracking, and there was none of this ‘cap a test frame to see if it’s centered’.  You took the pictures, and after minutes of painstaking guiding, you had to wait till at least the next day to see how well you did when you got the film processed.  Many a time I chuckle at night as to how what used to be hours of work, and a day or two to see the results from can now be effortlessly superseeded by a minute of scope time.

Later in the night, after visiting many a deep sky object, I turned the scope to Jupiter, then Mars, then the very late moon, all using the same magnification, just so I could give folks the scale of these things, all on the same magnfication.  The seeing was abysmal!  Mars was a swimming ball!  However all on the same magnification I got Saturn, Jupiter, Mars and the moon!

 

So yeah, I guess its like sex, in the dark, the first time is always a fumbled and inept experience.  However, having seen things in the broad light of day, and having had time to ponder on what went wrong and why, the second time can be more of the ‘tour de force!’ 🙂
