ffmpeg deinterlacing

[arrbee99 1817]

Was just having a go at deinterlacing an mkv using this  -

REM Testing for loop
FOR %%m in (*.mkv) do (
REM deinterlace MKV
ffmpeg -i "%%m" -vf yadif -c:a copy "%%~nm_deinterlace.mkv"
echo ====================================================

and it seems to work ok. Am just worried that the deinterlaced file came out a quarter the size of the input (a ripped DVD episode). Should I worry about that size reduction ?

Use vf bwdif, its much better

Hokey dokey. I'll give it a go...

Size reduction is (I think) being caused because you are using the native encoding settings - maybe add a lower crf value etc if the quality is not correct.

add :

 -c:v libx264 -crf 23

for example to your command line.
