byMAc Inventions I tried Time Lapse this summer

The time lapse, for those who do not know the principle, is to realize accelerated video of a scene from photos taken at a regular interval. To make time lapse, it's pretty simple. You need a digital camera, a tripod and an intervalometer
The idea of making Time Lapse with my camcorder was not new but I had not yet taken the plunge because I thought that I needed to invest in an expensive equipment. I have a Sony Nex VG 20 camcorder that makes beautiful photos, I have a good tripod, it remained only find an intervalometer.

I chose the Tempus Nex2 from byMac Inventions 69 $ which is about 50 €. My order went well and despite the site is in Portugal I've regularly been updated of my order tracking by email and I've received my package 4 or 5 days later.
This device is actually an infrared remote control that sends at a certain frequency a signal to the camear to shoot a photo. It is a small box a few centimeters which is battery operated (supplied and already fitted). Here's how it looks like :

Running it can not be simpler: an ON / OFF button on the back of the device, a diode, a mode button and a potentiometer to select the time between pictures. It is adjustable from 1 second to 30 minutes.

I positioned it around the lens of the camcorder using a simple elastic so that it is aiming the remote control receiver without interfering autofocus :

Then this is how I did it : I put the camcorder on a tripod, inserted of a large memory card (each photo weighs 5 MB and it takes 25 or 30 to form a second of final video whether you are in PAL or NTSC) , connected the camcorder to my house power plug (the scenes I filmed could last more than 3 hours), set up Tempus (see below how to calculate the interval) and turned on the camcorder.

In Studio I inserted on the timeline all the shot pictures, duration was changed to 1 frame and I exported. If the result seems too long, a little bit of proDAD introducing ReSpeedr and voila.

The formula I used to calculate my interval : I = Dr / (Df x 25) or I = Dr /( Df x 30) with Dr = real duration of the recorded scene and Df = desired duration of the final video.
Exemple : I shot a 1 hour (3600 s) long scene and I want my final video to be 30 s. I = 3600 / (30 x 25=) = 4.8 s. It results in accelerating vido by 120..

Here is a medley of time lapses I made this week at home :
