Problems rotating iOS12 screen capture video

I am running an iPhone XS Max, with iOS version 12.1.4 and created a screen capture. The screen capture was done with the phone in landscape mode, and I would like to rotate the video on my Windows 7 (64-bit).

I am trying to rotate 90 degrees counter-clockwise, where the max resolution is set to 3840x2160, and choosing rotate 90 degrees counter clockwise. The resulting video is split on the screen, and the resolution of the output video is 886x1920, which is the same as the source video, but it seems like it should be 1920x886 after rotation. I have attached a screen shot of the output video playing in VLC 3.0.6 on the same Windows 7 64-bit computer.

I was also unable to edit the video correctly, it showed up in a very strange way. The video has the rotate bit set, but only part of the frame is displayed in the timeline. I have attached a screenshot of that as well.

All of the above behavior happened with VideoReDo TVSuite V5.4.84.771 on a Windows 7 64-bit system.

Please let me know if there is any additional information that you need to solve these issues. I also have the video on Dropbox if you would like to see it.

Thanks,
Darin

If you save to MP4 with the rotation option set, and no other settings trigger a recode, then the original video is output as is and the only thing that is changed is the rotation flag in the MP4 header. If you want to physically rotate the video then you need to save to a format other than MP4 or do a force recode.

I did a force recode and told it to rotate counter clockwise 90, but the aspect ratio isn't right. I saved it to MP4 because that is the format that I need it in.

Hmm... it looks like the video is being physically rotated but the rotation flag is not being reset. Just as a test try saving to TS and see if the aspect is correct.

The conversion to TS made my computer work much harder than the previous attempts, and it is certainly better, but I don't know why the frame is shifted off the right side and shows up on the left side. I also don't understand the gray vertical box around the video, it's like VLC is confused.
