Luke 37046 Posted February 11, 2021 Share Posted February 11, 2021 When you select a quality of 4 mbps, it's 4 mbps total for the entire file, so the actual video bitrate will be less than that because you have the two audio tracks. One of those audio tracks is 640k, the other is 384k, so that sounds about right. So if you want the video stream bitrate to be 4 mbps, perhaps try entering 5 mbps instead. 1 Link to comment Share on other sites More sharing options...
Dedone 15 Posted February 11, 2021 Author Share Posted February 11, 2021 So if I selecte 5 mbps it will also keep the 4k res? And I don't understand how can I detect wich mbps I must choose for future conversions. Link to comment Share on other sites More sharing options...
Luke 37046 Posted February 11, 2021 Share Posted February 11, 2021 I would just try it and experiment until you find the one that you want. Link to comment Share on other sites More sharing options...

Dedone 15 Posted February 12, 2021 Author Share Posted February 12, 2021 this is the last conversion. I use 7 mbps and the result is the file with the same specs of the original and same size. It only make a 4k hevc file without any size reduction ffmpeg-remux-0af6a91f-aa62-498b-aa93-7abff0300c56_1.txt Link to comment Share on other sites More sharing options...
