No joke

Posted on March 31, 2020 by John

It is traditional for sheldonbrown.com to post an April Fool’s day page, but this year we couldn’t think of one that wasn’t either frivolous or, if it addresses the present situation, dark humor and potentially offensive to people who have lost friends. We do have this:

Selling Bicycles and Components

Posted on March 11, 2020 by John

We have expanded our article for individuals selling bicycles and components — which also holds advice for buyers. There is a new section about shipping. This article holds all the basic information you need on where to post an advertisement and how to create it — how to take good photos of the bicycle, and measurements so the buyer will be able to determine whether the bicycle fits.

Synchronizing Audio and Video

Posted on March 4, 2020 by John

Sheldonbrown.com technical writer and editor John Allen frequently shoots video from his bicycle using more than one camera; sometimes a separate audio recorder. The output must be synchronized in post production. John has now performed a major update on his article about how to keep the recordings in sync, going so far as creating true surround sound without a surround recorder.

Addition to post about 360-degree video

Posted on August 29, 2019 by John

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.
