| Jan 4, 2018 at 5:11 | comment | added | Gyan | That's from the CRF 28, which has heavier quantization. So stick to <24. | |
| Jan 3, 2018 at 21:53 | comment | added | netjiro | Thanks again Mulvya for getting back on this ancient thread. Perhaps I'm having unrealistic expectations. But take a look: goo.gl/YRsoH1 where encoding artefacts extend 10-12+ pixels away from edges of objects and flicker quite a bit from frame to frame. Is there a way to specifically tell the encoder to user smaller blocks, or to expect an environment of objects with sharp edges moving on a mostly static background? I remember people using special "anime" settings for similar effects on the old x264 encoders? | |
