My input source media is 1920x1080 25fps, compression "ALL-I", which means, according to CANON, compression image by image. Is it the same as 1080p or is it equivalent to 1080i ?
Following your instructions, I increased the Gamma setting first at 15 then 20. It seems to make the colors more vivid, but there is an increasing loss of information in the shades and the dark parts of the video.
I also tried to increase the vibrance in the color settings. There is a definite improvement and the result not far from the original. (NB: when I use MTS files as input, I have no loss of quality at all in the export files)
I have a subsidiary question: why, for most settings in the Publish and Share section, are there two files registered : one with the video and another one ?
Thanks for your help.
