Hello,
the following script will be used :
#!/bin/bash
while IFS= read -r -d $'\0' video
do
filename=$(basename -- "$video")
filename="${filename%.*}"
ffmpeg -y -i "$video" -vcodec libx264 -crf 51 -preset ultrafast
-acodec copy -f mp4 -movflags frag_keyframe+empty_moov+delay_moov p
Example of use of http://k.ylo.ph/2016/04/04/loudnorm.html
A way to get a video with a better relationship of loudness for speech,
music and "Action-Thunder"
Perhaps all ways known, perhaps not.
Example of video with ac3 + h.264
ffmpeg filter, /dual-pass/ mode :
1. Measurement with results :
I use ffmpeg for compression.
The result I do compare with https://github.com/vivictorg/vivictpp
Is there any hint, by ffmpeg, what to compare :
E.g.. Stand pictures, fast movie pictures ...
to see, whether missing information will be present.

You must know, Samsun has *no certified DLNA devices.*
A discussion with Samsung would be senseless, they have said : "They
have an own DLNA Standard.".

Hi,
I'm using ffmpeg for a long time, but I've just recently started to
use it with 10bit HDR (HDR10) video.
So far I found out how to re-encode HDR10 video with libx265 and
retain the HDR metadata. It's a bit complicated, but it seems to
work fine.

I would use Avidemux. It is based on ffmpeg.
From my side of view, you need an visual interface, whether the

But you must have in mind, an offset of +t of audio leads to no audio
