The VideoLAN Forums

I've got a 4k MP4 video shot on iPhone 13 that I'd like to remove the audio from using VLC. So under Media -> Convert/Save, I click Add and I choose the 4k video file, then I click Convert/Save, and I use a newly created profile called "MP4 muted" where:

Encapsulation = MP4/MOV
Video codec = 'video' is checked, and 'keep original video track' is checked
Audio codec = nothing is checked, i.e. no audio will be kept
Subtitles = nothing is checked

Then I choose a location and filename for the destination file and click Start. After a few seconds it completes and the destination file appears in Windows Explorer, but now the thumbnail shows that it's flipped and it comes up flipped if I upload that file to YouTube (but not if I upload the original file to YouTube, though then it's not muted of course). It still plays right-side-up in VLC for some reason but in the thumbnail and if uploaded to Youtube, it's up-side-down.
...
Another idea is that if this is probably just a problem with the metadata, maybe I can manually fix the metadata so that YouTube and Windows Explorer recognize the video right-side-up?

is there any other program that will remove the audio track from a video but leave the video track untouched?
