ffmpeg -i data/video.mp4 -vcodec h264 -b:v 1000k -acodec mp2 data/output.mp4 |
Just what I needed, went from 90mb to 5 and still looks good :) Thankyou 👍
Glad that you this help you :)
Can I just say though these don't work in IE9! :( Not sure why
Try changing the bit rate to a lower value something like 250k instead of 1000k and let me know if it helps.
Great I tried with
ffmpeg -i video.mp4 -vcodec h264 -b:v 1000k -acodec mp3 output.mp4
and went from 1.1 GB to 69 MB!!!

Glad it worked!
Hi @ksharsha I wish it worked on mine. I understand this would work on already compressed videos (my phone takes already compressed mp4 files, but I need to compress them further). I am trying to use Automator to do batches, like this:
for f in "$@"
do
/usr/local/bin/ffmpeg -i "$f" -vcodec h264 -b:v 1000k -acodec mp2 "${f%.*}.mp4"
done
pls how do i impliment this code

Not sure sorry.

You just run it on the command line.
anyway i can preserve my subtitles while transcoding and compressing from mkv to mp4? map doesnt seem to work.
Thanks, It works for me
from 137,6MB tobe 61,5MB
Thanks. it still work good.
hint:- if it increase the size of converted video, then try to reduce the bitrate (-b:v 1000k to 500k) for ex.
ffmpeg -i input.mp4 -vcodec h264 -b:v 1000k -acodec mp3 output.mp4
to
ffmpeg -i input.mp4 -vcodec h264 -b:v 500k -acodec mp3 output.mp4
It is not working for me sir...
showing me unknown encoder 'h264' and same for 'libx264'
I even tried other commands like:
'-i ${_storedVideoOne.path} -vcodec h264 -acodec aac $outputPath';
'-i ${_storedVideoOne.path} -vcodec libx264 -crf 28 $outputPath';
using with flutter_ffmpeg plugin
I tried mp2
and mp3
, all no audio on ios13.6, windows and android ok.
ffmpeg -i input.mp4 -vcodec h264 -b:v 1000k -acodec mp2 output.mp4
ffmpeg -i input.mp4 -vcodec h264 -b:v 1000k -acodec mp3 output.mp4
Finally I use with no -acodec
, all ok, and file size no big different.
ffmpeg -i input.mp4 -vcodec h264 -b:v 1000k output.mp4
