Hi guys, I have noticed that every Blu-ray I have watched contains (I think) compression artefacts - areas where there should be a little detail but there isn't and it looks really ugly. This happens mostly in brown tone areas. In order to improve quality and encounter the compression artefacts, I have come up with "MSU Super-Precision-Filter" () but this is a filter for companies only. It increases the bit depth of a video by adding false details. Is there any filter in Avisynth that does similar things? I have tried adding grain, also with GrainFactory3, but then the grain seems so smear when I encode the filtered movie with x264 and it adds "detail" to the entire frame, not only to probleme areas. Also adding grain costs a lot of bitrate... Any ideas? Regards moviefan
