Time-Lapse Flicker

Flickering is a common problem in time-lapse or stop motion footage captured
with a digital still camera. Frame by frame variations in lighting or exposure
lead to perceptible brightness fluctuations, or flicker.

Last year I wrote a plug-in for Adobe After Effects and Premiere that I call GBDeflicker. It removes flicker from video clips. GBDeflicker has been working well for me, so I decided to make a product out of it and have released a beta version for download from my site (granitebaysoftware.com).

This short video explains a bit about it and how it works.

Two Million Views On YouTube


Today, my YouTube channel passed two million views (or 4 million eyeballs). How the heck did that happen?

I created a YouTube account back in June and uploaded a couple of dozen time-lapse clips over the summer. At that time I had a only few thousand views. Then in September I uploaded the Reno Ballon Races video and things took off. What made it take off was getting "featured" (Who decides what is featured on YouTube is a mystery to me).

When a video is featured, a thumbnail imagage and link show up on the YouTube home page, so everyone on YouTube sees it. Hot air balloons must be some kind of primal subject that is of wide interest. While it was being featured, that video was getting about 50,000 views per day.

After a couple of weeks, the activity slowed down. But then in late October, it suddenly shot up again. It turns out that a rotting pumpkin video by someone else was being featured (as a Halloween gimmick) and my rotting fruit videos were showing up as being related (probably because they shared the same tag words). So as a side effect of another clip's popularity, some of my other clips were getting a lot of views.

Here's a table of the number of views for each of my videos.
