Hello guys,
We would like to inform you that we have decided to shut down our site.
The past 2 years have been very difficult for us – some of the people in our team died due to covid complications,
others still suffer the side effects of it – not being able to work at all.
Some are also fighting the war in Europe – ON BOTH SIDES.
Also, the power price increase in data centers in Europe hit us pretty hard.
Inflation makes our daily expenses impossible to bare.
Therefore we can no longer run this site without massive expenses that we can no longer cover out of pocket.
After an unanimous vote we’ve decided that we can no longer do it.
We are sorry 🙁
Bye
世事多變,珍惜當下。

TruthEar @2023-0129 之動心忍性篇
- 看到 YouTuber 諸多 TruthEar HOLA 的評鑑,不動心是不可能的,在 2023-0129 之前有春節特惠價活動。


- 但是靜下心來一回顧這半年不到的時間,涉獵這諸多 IEMs,實在需要好好沈澱消化吸收,再出發;終於在點擊之前停下腳步。
- 在 2023-02-04 再光顧 AliExpress, HOLA 566.19 NTD , Zero 1,490.45 NTD . 就這樣,促銷活動總會再有,先聽些好音樂吧!年後聽了 HAYA 樂團的蒙古草原音樂。

ffmpeg 2-pass
Assume to limit the output less than 20 MB.
- 1st-pass crf :
ffmpeg -i input.mkv -an -ss 00:55 -t 00:10 -pass 1 -passlogfile text.log -codec:v libx264 -x264opts crf=22 output.mp4
20 MiB = 8 * 20 Mib = 8 * 20 * 1024 * 1024 bits = 167772160 bits
bitrate = 167772160 bits / 10 sec = 16777216 bps = (16777216 / 1000) * K bps ~= 16777 K bps
- 2nd-pass 會參考 crf 22 的 bitrate 分配方式 等比例縮小到 16777 K bps
ffmpeg -i input.mkv -an -ss 00:55 -t 00:10 -pass 2 -passlogfile text.log -codec:v libx264 -b:v 16777k output.mp4
