I'd be most grateful if anyone can resolve this slight issue. I shot a few video clips with my Android mobile phone, all at the time of shooting, in Horizontal format, or so I thought. Until I downloaded them to my PC and discovered some clips in the Vertical format. So, using VLC, I managed to transform the Vertical videos to the Horizontal format, but useless VLC, then transformed the other already Horizontal format video clips to Vertical. I immediately uninstalled crap VLC! Windows Media Player plays the Vertical videos automatically in Horizontal. Great. Only problem I have is using Wonderfox DVD Converter to stitch(merge) all the video clips into one file, on playback check, it plays the Vertical format video clips as Verticals, which I do not want.
I’ve had this happen a lot with Android clips, especially when the phone was held sideways. Most of the time the video isn’t actually rotated, it just has orientation data that some players ignore. Re-encoding the clip and forcing the rotation usually fixes it, while simple “rotate” buttons sometimes don’t stick. If you’re doing it on a PC, make sure the tool actually rewrites the video instead of just changing metadata. On the phone itself, exporting a new copy after rotating often works better than sharing the original. I’ve fixed a few stubborn clips by running them through tools from https://www.movavi.com/. It helped apply the rotation permanently so the video plays correctly everywhere.
