An old colleague of mine, Max Whitby, has shot some infrared footage using a drone and the Near Infrared (NIR) version of the MAPIR Survey 2 camera, shooting HD. He calls the test shoot 'Max's Dream' and this reinforces the way this kind of footage, with lots of Wood effect, has a dreamlike feel.
Max's description of the drone fighting like a cat as he holds it suggests this is something for a skilled operator.

More snippets
Apologies for not posting yet this year ... but here are a few items to make up for it.
Towards the end of last year I came across a claim that a special diet could extend human vision into the edge of the near infrared.
Petapixel carried an explanation of the research project and also a rebuttal by a neuroscientist. The original crowd-funded experiment page is on experiment.com and the group carrying out the research is called Science for the Masses. Since last August the web seems to have gone quiet on the project.
A slight increase in deep red sensitivity would be useful for astronomers wanting to view the universe at the wavelength of hydrogen-alpha: 656.28 nm. Canon produced a camera modified to give similar better response a few years back and Nikon have now also done so, although theirs is a high-resolution full-frame camera. It's the D810A. The older Canon still had some infrared filtering in place so it couldn't be used for infrared photography, but it is unclear whether this is the case with the Nikon. The press release is unclear although DP Review suggests that there is still filtering.
For those of you interested in the BBC's natural history infrared shooting, there is a training film on line where Colin Jackson explains his technique. However, this his team moved on to using modified Canon DSLR cameras rather than 'pure' video cameras so the film is a little out of date.
Finally, a thermal imaging video showing cloud formations across the earth, shot from space at a wavelength of 6.5 µm. (This is worth expanding for a better view.)

The Pi NoIR: inexpensive nocturnal wildlife video
A further quick camera-related post. Andrew Back, an enthusiast for open hardware, has been using a Raspberry Pi (the tiny cheap computer) with an unfiltered CMOS imaging chip to shoot night-time wildlife. In this case it's, so far, mostly slugs and bugs caught using time-lapse photography.
See all the gory detail on the Design Spark blog.
30 October: Andrew continues posting his results on the Design Spark blog. Here's a time-lapse movie of the landscape near Hebden Bridge.

BBC Natural History infrared shooting tips
I've known Colin Jackson from the BBC Natural History Unit in Bristol for a few years. He has presented his work, filming wildlife at night using near-infrared and thermal cameras, at both the Infrared 100 symposium and at IBC.
I just came across a video from June 2012, tips on infrared filming, on the BBC Academy of Production web site. In it, Colin is shown using what he calls the 'kebab shop camera', a standard definition surveillance camera made by Ikegami. These days he is using a Canon DSLR with its infrared-blocking filter removed which will produce HD resolution images. You should also know that, if memory serves, his infrared lighting is at 920 mn.
What he doesn't talk about in this video is using thermal imaging. There, as you probably know, you don't need lighting as a thermal imager shows the photons generated by the objects themselves.

Infrared on Red
I've noted before the suitability of the Red movie camera for shooting near infrared footage and the suitability of infrared for shooting clouds and a superb example has now been brought to my attention.
This is the work of Glen Ryan and James van der Moezel and as Glen writes,
The Karst formations are near Wee Jasper in New South Wales and the video was part of a recent exhibition called Karst County held at the Belconnen Arts Centre in the Australian Capital Territory (Canberra). Here Glen Ryan's photos and video were exhibited alongside Phil Ryan's acrylic paintings.
The infrared video was shot with a Red camera using 'Nikon glass' and an R72 filter (presumably the Hoya of that ilk).
Watch the video at full HD resolution if you can ... preferably in a darkened room.
This is the work of Glen Ryan and James van der Moezel and as Glen writes,
"... is only a very short section of a much larger project - in scope, duration and resolution (4K) - that I am currently working on with emerging cloud wrangler James van der Moezel."He promises a six hour uncut version soon.
