Hi , Last days i did some tests with fast scenes clips to convert to Theora with ffmpeg2theora , i see a lot of squares in result Theora clips. And i get an idea for Theora Encoder , i see that in ffmpeg2theora you can choose sharpness from 0 to 2 , and i think this is a feature of the Theora encoder library. Well my idea is that the Theora library enconder implement something like Smart Sharpness Controller , in fast scenes encode Theora in Sharp mode 2 (blur mode) and in static images or less speed scenes enconde in Sharp mode 0 (the most sharp) or Sharp mode 1 depends of the video quality selected. _________________________________________________________________ Hor?scopo, tarot, numerolog?a...
