A quick test of GoPro/Cineform's new Protune firmware. (If this were a Vermeer painting it might be called 'Man With Laptop').
This highly unscientific test was designed to compare the original firmware with the new Protune firmware in terms of noise, dynamic range and gradeability.
In my view the higher bitrate log-style Protune image is cleaner, has better dynamic range (look at the window in the left of the picture) and is more suited to colour grading than the original firmware (or standard mode if you prefer).
In brief, it does what it was designed to do.
Watch the video and make up your own mind.
Download the original H264 file if you want to watch a less compressed version.
Please consider making a donation via the 'tip jar' if you found this video useful/worthwhile etc.
Note: In the remapped grades there's some blotchy noise in the top right of the picture (by the door). This is because the shadows have been pulled up so much. Could probably get rid of this by spending longer reducing noise (I only took one noise sample, from the wall).
