Thanks to Philip Carlson, our article about 360-degree video now includes a video clip illustrating the nighttime performance of the Garmin VIRB 360 camera. As expected, there is camera-motion blur, but it looks much different from that with a conventional camera.

Rebuilding freewheels
We have a much expanded description of how to rebuild a freewheel, now a new article and no longer just a paragraph in our main article on freewheels.
Revisions to Sachs/SRAM Internal-gear hub pages
Every once in a while we go back and review our pages to deal with product changes and link rot. We just did that with all our pages about Sachs and SRAM internal-gear hubs. You will find product manuals here which are hard to find anywhere else. You can start with our main page about these hubs.
Deinterlacing video
We have many pages about shooting, editing and processing bicycle video. Here’s a new page about deinterlacing. What is that? well, the page will tell you. It can do a lot to improve the quality of older standard-definition video footage, and especially, footage shot with a camera in motion. Deinterlacing cleans up the image and doubles the frame rate for smooth motion. Here is a deinterlaced video running at 60 frames per second. If your Internet connection supports the 60 per second frame rate without skipping frames, this is going to look super-smooth. Click on the title and expand the image for best results.
Shining Sea Path at Ter Heun Road from John Allen on Vimeo.
What is this video about? Two cyclists cross Ter Heun road on the Shining Sea Rail Trail in Falmouth, Massachusetts, USA. The crossing is close to an intersection and has a gate in an attempt to slow cyclists down, and a sign instructing cyclists to walk their bicycles — which may be preferable for a person with poor bicycle handling skills but is slower than riding, and so increases the likelihood of being caught by surprise as the traffic situation changes. More about this intersection is at http://john-s-allen.com/blog/?p=7862
The video here is formatted at 60 frames per second. A display which runs at that speed or a multiple will show smooth motion. I’m getting that result when viewing the video on vimeo, though not with the video embedded in thsi page.
Addition to freewheels page
There’s a new section in our freewheels page showing how freewheels work and what is inside.
