So, for a recent project I was required to prepare some AVCHD files (sync the mic audio,fix some minor issues here and there and remove some noise) in order to proceed to editing later...
I tried exporting (in after effects) in h264 but there was a signifincant quality loss with some terrible banding.
My question is, what is the right codec to render those files without losing quality and keeping the file size roughly the same?
On a general note, does compressing the file with the same codec many times reduce the quality?
What workflow would you suggest for my case?
