So,long story short - trimmed my go pro video with VLC and when played on PC video is good.
When uploading to YT it ends up flipped.
I can only assume it has something to do with the camera being flipped when original was recorded, at the same time go pro has auto-rotate and
this does not affect video at all in the end.
Tried converting into different formats again, with VLC - to no avail.
I am not that deep into editing software but it would seem there is no way to edit meta data, I was able to identify the probable cause with this app MediaInfo, where I found the ROTATE line with 180 next to it as seen in my attachment.
edit: adding yt link for more clarity
Any help would be greatly appreciated
Cheers

You can remux it into a mp4 container and then rotate it (metadata only, no recoding):
Code:FFmpeg.exe -display_rotation 180 -i "Your_hevc.mp4" -c copy "Your_hevc_rotated_180d.mp4"

Prowo's code is faster than this one with no recoding as he posted.
It does the same as this one but this one does recode (not a major recode):
Code:ffmpeg -i input.mp4 -vf "vflip" output.mp4
Code:ffmpeg -i input.mp4 -vf "hflip" output.mp4
Prowo's Clever can also do it but does recode also.
You can not just select Various & Rotation.
Choose Main\Video Stream\KeepSize\Various\Rotate\Flip Select the option you want.
Select the encode options you want.
Then Encode -

@Prowo,
I was testing with an .mp4 as I did not have a HEVC.
I should not need to remux this .mp4
I'm using v3.3.0 on a 32-bit Windows 7.
I just tested it again & no rotation.
This same .mp4 did rotate when I made the settings I posted in #3 -
What video codec?
It works with h264, hevc and mpeg2 in mp4 and mov container.Last edited by ProWo; 20th Sep 2024 at 15:51.

@Twinax, could you attach a short video for us to play with? I may have a GUI option.

All the flipped files are over 500MB and it would not let me up them, try to download the video off my link, I have updated it with a smaller size vid
Also thanks for all the replies, the codes you posted I have no idea how and where to execute, I assume console?
in the meantime I was able to find a way via VLC's convert feature to enable a vert flip filter and transform the files into
a result which was flipped when played on PC, but on YT it would upload great.
When I get the time I will do a test- I will record a new video with the camera flipped, trim with VLC and see if it does it again. Whenever that day comes - I am posting the result here, cause this was so peculiar that it must be documented. I did trawl through a lot of search results on Gogale and nothing even close to matching my case.
Have a good day, and a great weekend all! -
We'll need the original video. YT completely recodes video so the original metadata will be lost.
I was going to suggest AVIDemux, which can also be used create do a lossless snippet. My tute for snippets and rotating without recoding is here. Note that sometimes, the rotating doesn't work without a full recode. You may be lucky though and get a lossless recode, right way up.
You can keep your snippet to around 5 seconds. That's all that is needed.
