mxf XDCAM 1080i MPEG-2 25 Mbit/s interlaced contents to 4K HEVC 50fps progressive. ![]() I gotta send a sample to a TV which requires constant bitrate (20 Mbit/s) HEVC 10bit 50fps. ![]() When psy-rdoq is too high you'll just get compression artifacts. When psy-rd is too high, you'll typically see motion inaccuracy (for example, blocks that should be portraying smooth motion that instead appear to be staying in one place too long). A little psy-rd is good, but too much psy-rd strength will cause x265 to choose candidates that aren't the best match visually (blocks that have higher or matching energy levels, even though they are not the best candidate with the lowest Rate-Distortion cost). Psy-rd biases mode decision towards candidates that have a similar level of detail (variance) to the source block. Try re-encoding with default placebo settings, and let us know what you find.Ĭompression artifacts will occur if you set the psy-rd strength and/or psy-rdoq strength too high. ![]() In this test-example, artifacts of macroblocks 64х64.
