![]() I aim for ~CRF 14-15 when I compress my videos, to actually retain any quality to speak of. So a low quality input can indeed become larger.Įither way CRF 28 is ludicrously high compression in libx265. ![]() The downside is that it can attempt to retain information on something that is already poor. It will up and down the bitrate as is required on it's own. Also the reason why CRF is superior, because irrelevant of input the output is a constant level of retained quality by which the encoder is given rather free hands in achieving. Since each encoders CRF scale is different. It is as the name suggests, a constant for said encoder. Basically, a measure of how much to keep or throw away from any given block. ![]() CRF, Constant Rate Factor, is a setting to maintain a constant quantization parameter. Just make sure to tag the post with the flair and give a little background info/context. On Fridays we'll allow posts that don't normally fit in the usual data-hoarding theme, including posts that would usually be removed by rule 4: “No memes or 'look at this '”
