When you use RF 0 quality with x264, you’re telling HandBrake uncompresses the video prior to conversion, the quality lost when theĭVD was made is still gone. Make them – sort of like a quality level of RF 20. See, DVDs use lossy compression to squeeze down the raw video the studios use to Inįact, you’ll end up with video that’s way larger than the DVD, but doesn’t look So should you use RF 0 to perfectly preserve the source? Nope. It is lossless: it compresses the source without In the middle of your source should give you a good idea of what to expect. Values if the above recommendations are not suitable. You can encode a few chapters of a source to experiment with different quality You can control the granularity of the slider in Logarithmic (like the Richter or pH scales.) This means small movements in the You should note that the quality slider is not linear for x264. Value than SD content without any perceived difference in quality. Sources are typically quality, you can get away with a slightly higher RF High Definition (e.g Blurays 720/1080) Use an RF value of 22 +/- 1 Since HD Standard Definition (e.g DVD’s) Use an RF value of around 20 +/- 1 As anĮxample using the AppleTV2 preset at RF20, with 20 different sources, theĪverage size was 925MB per hour of video. Quality output at reasonable file sizes, the following values are recommended: The Quality slider ranges from (Low Quality) 51 to 0 (High Quality) For good You should also note that even if a file size is significantly smaller than aĬounterpart encoded with target filesize, it does not mean it is any lower Try turning on the “Denoise” filter or reduce the RF value a few points. In particular, grainy sources tend to come out larger as they require a higherīit-rate to maintain all that extra detail in the video. Source material is consistent, you will get roughly the same file sizes out for The difference can be more or less depending on the source. Given part of any movie, the output size is unpredictable and varies from sourceĮxample: Given 2 sources of the same length, one could turn out to be 1.2GB, the If less complex frames do not have bits wasted on them, your overall outputįilesize is reduced without any loss of quality.īecause it takes a different bitrate to reach a given quality level for any (The latter requiring less bitrate to achieve a set quality level) Reduced file sizes Videos usually have a mix of complex and less complexįrames. HandBrake adjusts the bitrate (that is, the size) to meet it.Ĭonstant Quality Benefits over Average Bitrateįaster Encoding - No need to do 2-Pass encoding (thus almost halving theĮncode time.) Constant Quality can produce the same quality as a 2 pass Constant quality mode does the opposite you specify a quality level and.With the average bitrate, you control the size of the output file but give.
