Command: ffmpeg -i input.mp3 -codec:a libmp3lame -b:a 192k -write_xing 0 -id3v2_version 0 output.mp3 Details: Camtasia 8.6 misunderstands VBR: Variable bit rate MP3 files. So Camtasia 8.6 shows the wrong MP3 audio length. To avoid this Camtasia 8.6 issue, use CBR: constant bit rate and invalidate new headers. (Or use a WAV file) Options: -b:a 192k : Constant bit rate to 192kbps -write_xing 0 : No Xing header. The Xing header records the timing information for the variable bit rate MP3 file. But when I use CBR, this is not needed. Camtasia 8.6 seems to have failed to recognize Xing VBR MP3 files. -id3v2_version 0 : Use id3v2 version 0 tag. Camtasia seems to have failed to recognize the ID3v2 header > 0 tag. This loses the metadata. To see the MP3 encoding info: ffmpeg -i input.mp3 mediainfo input.mp3 

I am a premium YouTube user to get less noise. The "most relevant" section is quite irrelevant for me; it is noise. I looked up how to disable that in YouTube settings, but I could not find it. I found I can use UBlock Origin -- Custom filter, and set the following. youtube.com##ytd-reel-shelf-renderer:has-text(Most relevant) youtube.com##ytd-rich-section-renderer:has-text(Most relevant) Thanks to UBlock developers.
