Megui新手，幫手睇下壓得掂唔掂.
本帖最后由 ka159753 于 2017-3-18 19:37 编辑Megui新手，幫手睇下壓得掂唔掂.
今日搞左成日，終於識用megui壓片，差啲比啲error搞死..

因為係1080i，所以壓制時開左TFF
有意見可以提出黎。
以下係壓制參數
我係用2passauto壓制嘅
碼率3150kbps

呢個係文件詳情。。打錯
质量麻麻地色块严重不够码表现，编码方式而家没人用2pass时间长质量又唔系好

const.quality?新手求教= =
啱啱網絡慢= =連發左兩條。。。
cfr一次编码自动计算码率，动画720p我用23，数值越低质量越好同时体积都越大
你自己慢慢研究另外cfr压出来体积不可控制动态画面多体积大相反静态就细。

感謝漫步提點！我都改進緊，原來megui 2pass咁唔好架 noname 发表于 2017-3-18 19:12

cfr我用21壓覺得幾好= =平均有3.7M碼率 睇下点样先
