I found a way to minimize blocking artifacts in HDV blacks. I would like to explain and if someone try it, let me know.
1 - put the same m2t footage aligned in two video tracks in Adobe Premiere.
2 - in the upper track apply gaussian blur and adjust between 4 and 6.
3 - in the upper track apply arbitrary map and adjust between -5 and -1
4 - in the upper track apply luminance key (adjust the key to keep only the blacks of the upper track over the lower track, be carefull to not get color fringing in key edges)
5 - render to uncompressed.
The goal is to minimize the blocking artifacts in the blacks where HDV compression is more visible.
Thanks.
