Zathras: It appears your assumption (6) that the files are "exactly the same" because the spectrograms are the same is not correct.
I downloaded https://www2.cs.uic.edu/~i101/SoundFiles/BabyElephantWalk60.wav as a test file and converted it with the freeoconvert.com online converter, and ffprobe reports the following: % ffprobe BabyElephantWalk60.mov ... Stream #0:1[0x2]: Audio: aac (LC) (mp4a / 0x6134706D), 22050 Hz, mono, fltp, 72 kb/s (default) Metadata: handler_name : SoundHandler vendor_id : [0][0][0][0] That is, the online converter you specify has converted the audio to AAC. That is, you should be able to use simply ffmpeg -i picture.jpg -i music.wav upload.mov and accept the results. Alternatively, discussion in this thread suggests you can use the FLAC encoding, which is lossless. I agree that the responses you received to your inquiry were rude and unprofessional and have no place on this mailing list and I am sorry you had to deal with them, and I do not understand who administers this list or how to resolve those issues. -- jh...@alum.mit.edu John Hawkinson On Thu, May 23, 2024 at 7:12 PM Zathras Yes <zathras.the.fi...@gmail.com> wrote: > Hi, > > as i have mentioned to Mr. Reindl, the online-converter > https://www.freeconvert.com/wav-to-mov does the trick. > > ffmpeg should be able to do the same, I suppose. > May be, I am in error, may be not... > > 1. make a wav-files (16 Bit, 44.1 kHz) "sound.wav" > 2. use the mentioned online converter from "sound.wav" to "upload.mov" > 3.
