Questions & Answers

What is Simple Deflicker?
Simple Deflicker is a minimalist software tool designed to remove flicker from image sequences, such as timelapses. It achieves this by using a histogram matching technique to smooth out brightness inconsistencies between frames.
Who would use Simple Deflicker?
This tool is intended for photographers and videographers who create timelapses and encounter brightness flickering issues. It is particularly useful for sequences where camera settings were left on "auto" and caused inconsistent exposure.
How does Simple Deflicker compare to other deflickering tools?
Simple Deflicker is characterized by its minimalist approach and ease of use, focusing specifically on global flicker caused by camera auto-settings. It currently supports only JPG and PNG (8bit) files and does not handle rolling flicker or metadata transfer.
When should I use Simple Deflicker for my timelapses?
Use Simple Deflicker when your timelapse sequence exhibits global brightness flicker, often due to a camera switching between two auto-exposure settings. It is effective for smoothing gradual brightness changes, like during day-to-night transitions.
How does Simple Deflicker fix flickering?
The software employs a histogram matching technique. It analyzes the brightness levels across frames, creates a rolling average to account for natural light changes, and then adjusts each frame's brightness to match this smoothed average.
