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
