Hello and thx for replying.
To be honest i didn't understand what you are telling me.Sorry.
In any case i had to make the following changes in order to compile
ffmpeg as usual.
-enabled libmp3lame && require "libmp3lame >= 3.98.3"
lame/lame.h lame_set_VBR_quality -lmp3lame
+enabled lib
Just tried with "-c:a copy" instead of "-c:a libfdk_aac -b:a 192k" and the
output actually got slightly bigger...

Trying encoding with the pixel format right now.
Already got a warning:

set range correctly

Carl,
Thank you for your comments.
Can the option "-pix_fmt yuv420p" be harmful for my files?
I mean does it make outputs any worse if I watch them in a modern player
such as VLC?

Is there anyway to see which filters are among those?

Only for filters that contain specific GPU code (very few).

Please start with "ffmpeg -i video1.mp4 -i video2.mp4" and provide
the complete, uncut console output, remember that only current
FFmpeg (git head) is supported here.

I wrote a script to compress all my videos (posted here:
https://github.com/AndriusWild/dam_scripts look for compress2mp4.sh)
I guess I will have to invest more time in it and make it use different
FFmpeg commands depending on the input...

Moritz,
Thanks a lot for the explanation. I think I did post the full console
output.
As for the yuvj420p, does it reduce the quality?
Broader compatibility is one of the things on my priorities list for sure.

The purpose for which I am using the script is to compare two files for similar

I use this command to compress videos made by my family members with their

Hi all,
From ffmpeg documents I see that video encoding can be GPU accelerated.
Would the same be true for filtering operations?
