Algunos vídeos.
Por ahora parece que nadie tiene una comparativa entre el modo standard de gopro y una toma igual "con graduación de color y contraste" debajo del agua y con poca luz. Sin retocar el color y contraste lo normal es que el protune se vea peor, con menos de todo. Pero con retoque se puede obtener el mismo modo standard, con mejor calidad u otros standard (colores distintos) que serían imposibles de obtener desde el modo standard.
Some color correction tests using the new GoPro "Protune" option.
Direct video off the camera is unsharpened and uses a flat color profile similar to Technicolor's Cinestyle profile.
I demonstrate color correction using the GoPro provided Cineform preset, and also two Cinestyle corrections I already had loaded in FCPX.
I also compare against 1080p Standard footage.
Best watched full screen at 1080p. The footage is straight off the camera.
This is a shootout between the new GoPro ProTune Picture Profile, vs the Standard Picture Profile. ProTune is recording at 35mbps vs the standard 15mbps, and has a flat color profile with 11 stops of dynamic range, vs the standard with hyped colors and blown out highs. Straight off the camera the color is a bit subdued with ProTune, but that makes for more room to push it in post. You may want to use the standard profile if you don't want to do anything with the color after you record the footage. I do notice less moiré on certain surfaces, which is great.
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).
Thanks

For 35 Mbps a class 6 is sufficient in terms of bit-rate
35Mbps is only 4.375 MB/s but not all lower end cards are exactly 100% to spec and may drop below that rate at times and there are lots of dodgy SD cards around these days being sold online. As the HD2 still needs a c10 card for its .5s timelapse mode its the best way to go so you can use all modes with no issues but beyond that spec all your going to benefit from is faster transfer speeds or if you also use the card in another camera that will benefit from it.
