Apologies. I should have tried it out first. You are correct. Even specifying r:v and -b:v failed.-------- Original message --------From: jmkhoo1 <jmkhoo1-at-yahoo....@ffmpeg.org> Date: 8/10/2017 9:28 AM (GMT-05:00) To: FFmpeg user questions <ffmpeg-user@ffmpeg.org> Subject: Re: [FFmpeg-user] CBR and bitrate If you mean a constant frame rate, use -r:v 25. If you actually mean bitrate, use -b:v and -b:a. I think you might want to look at the x264 switches to make sure that it is encoded and a constant bit rate, though I am fairly sure specifying a bit rate will do it.-------- Original message --------From: akash kulkarni <kul.akash...@gmail.com> Date: 8/10/2017 7:18 AM (GMT-05:00) To: FFmpeg user questions <ffmpeg-user@ffmpeg.org> Subject: [FFmpeg-user] CBR and bitrate hello everyone
