Following my earlier Protune test for the GoPro, I gave it a try and saw what some quick&dirty manual correction in KDEnlive could do to raw GoPro footage. So here's a new comparison:
- Indoor and outdoor pans each time, this time during better viz outdoors
- FIrst, a comparison of the non-Protune setting of the GoPro versus Protune straight out of the cam, Ie no corrections applied. This is pale and murky, as expected
- Then, the same non-Protune scenes compared to Protune footage being compensated by the Protune setting of Cineform for Windows. One can cleary see how Cineform goes extreme with the saturation
- Finally, a comparison of the previous Cineform-corrected Protune footage versus a manual correction in KDEnlive
All scenes shot on a GoPro Hero 2, FW HD2.08.12.222.WIFI.R56.00 1/8/2013, 1080p 30fps.
My conclusion? I have to revise the conclusion from my previous vid! It's actually no magic to tune Protune footage to match or even outperform the Cineform footage. And there's a clear benefit over non-Protune footage. I have now a set of correction parameters for KDEnlive that'll serve me well as a starting point for correction of Protune footage. I guess Protune on is my new default setting at the GoPro -- unless I need the card-space, that is. Protune boosts data rate from avg 15Mb/s to 35Mb/s!
Note: If you're interested in the filter stack for KDEnlive 0.9.2, let me know. I'll happily share.
