Why after rendering with ffmpeg, file size did not decrease ?
15 avril 2021, par ptrraPROBLEM : After rendering a certain video with
ffmpeg
file size increased from 4GB to 6GB.

ORIGINAL VIDEO : EE1.mkv

FFMPEG COMMAND :ffmpeg -i EE1.mkv -c:a copy -c:v libx264 -crf 23 -preset medium -profile:v high out.mp4

QUESTIONS : Why did the file size increase ? What am I doing wrong ?

!DETAILS !

After a few years I made about 30 gaming videos (130GB) and with the current covid-19 situation I started recording my online classes (about 40 videos or 150GB). Now because I'm lacking space on my 1TB external HDD I started getting intoffmpeg
. Before I was only usingobs-studio
and not good parameters for recording.

I was using
CBR
mode for recording, either 5000KB or 15000KB bit rate with varying x264 presets and profiles because I was also experimenting with them. Usually superfast preset with high profile. So I wanted to convert all those videos withffmpeg
usingCRF 23
, medium preset and high profile. A note that when I'm recording withobs-studio
it's set to record in matroska format (.mkv
).

When I was rendering my online classes videos with these settings I managed to achieve 10x better compression with the same quality. And when rendering my gaming videos I managed to achieve up to 3x better compression with the same quality. However there is this one video that when rendered with the same parameters the file size increases.


The EE1.mkv should be recorded with
CBR
15000KB bit rate, with superfast preset and high profile. Also the game that is recorded in this video isEmpire Earth
which needs around 8000KB for it to look good. Everything more than 8000KB is not needed.

Thank you all for your help.
