4. drag&drop the removedarkness.avs into virtualdub and hit "play" to get a live preview. the video may stutter at this point, but your exported video will play fluently. the problem: i have a long-term time lapse videos that contains not just daylight footage, but also very dark footage captured during night. the camera used – the brinno tlc200 pro – actually has a setting to stop recording at night, but this only takes effect after several dark frames, resulting in a video that lacks fluency.
manual removal of these night frames is only an option for videos covering a few days, but not for long-term footage.

there is a way, however, to drop night frames automatically using free, open-source software. here’s how: [more…]

for the past few months, i’ve been wearing meru zip-off pants when outdoors and/or traveling. the manufacturer promises that the fabric used, called armadillo (65% polyester, 35% cotton), is “virtually mosquito proof” and i’ve been wondering how much this promise really holds in the wild.
on a recent field trip to what can only be described as “mosquito land”, i noticed that many mozzies were actually trying to bite through the pants, but eventually gave up. here’s a short video that shows one of these mosquitos trying to get through the fabric, and failing miserably:

isn’t it fascinating how bendy these probosces are?

in mid-march, the hochmahdkopf forest fire claimed a total of 120 hectares of protective forest and turned into the biggest forest fire in tyrol’s history. restauration measures are expected to take about 15 years.
about three weeks after the fire, i did a short hike to check out the latschenegg site, and it looked like nature was beginning to reclaim the charred area:

following the market research on construction time-lapse cameras and brinno tlc200 pro + eyefi first steps articles, i’m happy to present my very first construction (or rather, destruction) time lapse recorded with the brinno tlc200 pro camera:

the video above was partly processed with avifrate (to slow down the second segment) and edited in gopro studio.

below you’ll find the unedited video output, some information regarding image quality, and more. [more…]

motodup ride from ban lung to koh nhek if you’re traveling to the northeast of cambodia, you might find yourself trying to find a direct route between the major towns of rattanakiri and mondulkiri: ban lung and sen monorom, respectively.
as you’ll read in the travel guidebooks, there’s no direct bus connection, only a nightmarish road, and a very bumpy, expensive road. however, road conditions have greatly improved, and it’s not necessarily as difficult to organize as it once was.

update 2015-08-19: this tutorial doesn’t seem to be working anymore. try the updated, simplified GoPro Studio conversion article instead.

how to convert an .avi file for use in gopro studio, using only freeware GoPro Studio is a great piece of video editing software, especially for two reasons: firstly, it’s straight-forward and easy to use, and secondly, it’s available for free.

GoPro Studio (formerly: Cineform Studio) is compatible with “GoPro, Canon, Nikon and other constant frame rate H.264 mp4 and .mov formats”, but what can you do if you’d like to edit videos from other cameras?
you can use MPEG Streamclip 1.2 to quickly convert any video into a format that can be imported directly into GoPro Studio.

update: after some complaints, i’ve re-tested the method on two computers and several .avi files from various cameras. for me, works fine with GoPro Studio v. 2.0.1 and v. 2.5 on two of my computers (be sure to click on “Step 2”). see comments for details.

just one cigarette started a forest fire in absam this morning, which quickly spread to an area of about 3 hectares.
at night the scene looks both scary and beautiful: entire hillsides are glowing bright red. every few minutes, presumably when a new tree has fully caught fire, flames rise up several meters in the air, so that even from several kilometers away you can clearly see them with the naked eye.

fire fighters, the military, and even private helicopter operators have tried all day to contain the fire using six helicopters, but the dry weather and wind have made these efforts difficult. rain is expected on saturday.
the good news is that, as far as i know, no houses or settlement are in danger.
