AutoMKV x264 Encoding final size is not what i request
Hi. Im encoding a x264 video using Constant Quality profile and i set the output file to be 8GB (Disk Settings input is set to 8000). The original is 16GB. Is ok if there is some quality loss but the output file is not 8GB, its always larger like around 9.5GB. Im use no resize filters and original width resolution allso no audio track. Why the output is not the size i request?

You cannot use crf (or qp) rate-control mode(s) and know the final file size. If you want to get a specific file size you will need to set the correct bitrate to reach it. You can use crf as the first pass but on the second you must set the bitrate you want.

You should update your AutoMKV to 0.98.4 here

I ment maximum quality on terms of reducing the fail to 8GB. (I know qulity will reduce compared to original) So if I just use 2-pass mode and set the size final to 8GB I get exacly 8GB and i dont have to calculate the bitrate myself?
Im using AutoMKV version091 |
