Hello,
the video file in vlc player plays correctly,
If I add the video to the vMix input, it flips 180°.
This problem is only with videos in :

MOV
Format : MPEG-4
Format profile : QuickTime
Codec ID : qt 0000.00 (qt )
File size : 1.35 GiB
Duration : 12 min 31 sec
Overall bit rate : 15.5 Mbps
Encoded date : UTC 2021-10-05 07:42:34
Tagged date : UTC 2021-10-05 07:55:05
Writing library : Apple QuickTime
com.apple.quicktime.make : Apple
com.apple.quicktime.model : iPhone 8
com.apple.quicktime.software : 14.7.1

To test it, I send a video download here :
https://www.uschovna.cz/...ka/QWIZJP2KF8R7CIPX-B28/

When I convert the video without editing in Adobe Media Encoder to :
MP4
Format/String : MPEG-4
Format_Profile : Base Media / Version 2
CodecID/String : mp42 (mp42/mp41)

The video file will display correctly in vMix.

Why is this error occurring?

Thanks a lot for the answer.

Have a nice day

Regards

Petr Marecek
