I need to keep Video High quality when uploading to phpfox

Question

Hello friends,

I enabled video upload in phpfox, but I got this issue: Video is low quality and grainy.

I think that is on FFmpeg settings or Mencoder settings.
Do you know how to configure ffmpeg for best quality?

Thank you!

Answer 1

Yes, the quality depends on how FFMpeg has been configured and which codecs they are using.

We recommend these configurations for Video settings:

Requires FFMPEG, Mencoder, FLVTool2.

Params for FFMPEG:
-qscale 3 -i {source} -vcodec h264 -b 4000k -s {width}x{height} -ar 44100 {destination}

Params for Mencoder:
{source} -o {destination} -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate=800:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -vf scale={width}:{height}

Fallback Params for Mencoder:
{source} -o {destination} -of lavf -oac pcm -ovc lavc -lavcopts vcodec=flv:vbitrate=800:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 22050 -ofps 24 -vf scale={width}:{height}

It work for all file formats: mp4, mov, mkv, 3gp...
