Do you only get that error when converting from webm to mp4? What about another source video format that’s not mp4? Can you see anything unusual in the FFMPEG Test Output at the bottom of the FFMPEG Settings tab of the plugin settings page?
Thank you for the lightening fast reply 🙂
I didn’t try to convert any other format until now.
At the end of FFMPEG test output I get this:
Unrecognized option ‘rc_lookahead’.
Error splitting the argument list: Option not found
My server support says this:
I investigated and this doesn’t seems to be server issue. The second screenshot shows that error is “Unrecognized option rc_lookahead”. And the command is using x264 encoder. As per below documentation URL rc_lookahead cannot be used with x264 encoder. It’s only available on libvpx-vp8 and libvpx-vp9 encoder.

It sounds like you have the “Enable legacy libx264 parameters” setting enabled in the FFMPEG Settings tab in the “FFMPEG legacy options” section. You should usually only enable that if you have an extremely old version of FFMPEG.
Thank you very much for your help. It works now! 🙂
