https://github.com/argorar/WebMConverter/releases/tag/3.42.0>select video>trim/crop clip as you need in the main filter menu>run it through with audio one time: ensure high quality mode in the 2nd tab and vp9 in the 3rd tab are disabled, enable audio in the 2nd tab, nothing else matters we just want the audio>Use either ffmpeg itself or just an online converter to rip the audio if you don't know how to use command line>Get the target bitrate from the file with audio: open the video in a media player and look at the duration (you want the video duration to a precise decimal value if possible, if not just round up to the nearest second), then simply divide 32000/(video length)>In the second tab, activate high quality mode (this is 2-pass encoding, very worth), set desired bitrate to the value from the previous step, and then activate vp9 in the 3rd tab again and wait>Build the soundpost: if you use the separate soundpost player it has functionality to do this for you, otherwise just rename the output video file to the soundpost format ripped from another post, upload your audio to catbox, and then replace the part after the last %2F in the filename with the part after the / in the catbox file link (i.e.in [sound=files.catbox.moe%2Fphzj6m.ogg] replace the "phzj6m.ogg" with part after files.catbox.moe/ in your link)Congrats, you just made a soundpost. You don't have to use VP9 or 2-pass if you don't want to it's just for better quality/compression for web video with tight filesize constraints at the cost of encoding time.
Alternatively just post it here and I can make it. I would not recommend the fast soundpost makers method for most people that guy is honestly a lunatic and I think it genuinely just doesn't work if you're not following his pipeline exactly, he's a FREAK
