Vertical Video (Portrait) Proxies rotating when used

I have been on this issue and i have resolved it by creating a new ingest preset in media encoder.This happens because the presets that came with premiere pro is crafted for landscape videos only and in this case we seem to be using a portrait video.Simply go to media encoder,go to the panel on the bottom left and click on the plus button and create encoding preset.A panel will emerge and you can put your own preset name.Unnder the export settings panel there is the basic video settings.Then the width and height states that it is based on the source.You must untick it since it will create proxies with the SAME resolution and be useless.So untick it and change your height and width

You can type 1280 for the height and 720 for the width

or 960 for the height and 540 for the width or you can just type anything as long as the aspect ratio between the height and width are the same.Oh i almost forgot you can change the video format of your proxy accoding to your choice.Then click ok and there should be a new file named after your preset name.Then click the plus button again and click on create ingest preset.You can name your preset.And there should be a section under general setting which is for transfer options.Ignore it and under it there is a transcode files to destination.You wanna tick it and the destination should be where you want your proxies to be.There is a preset option under it and choose the encoder preset you created earlier then click ok.Then there should be another file with the name you typed and under the format it should say ingest.Click it and press export presets which is the button on the left of the search bar on the bottom left panel.Chose your destination and remember it and youre almost done!To use it,in premiere pro ingest settings there is an add ingest preset option on the right of the presets panel.Simply chose the ingest  preset file which you exported earlier and Done!Your proxies should be at their original aspect ratio.

Could you try switching the Renderer to Software Only and see if that works around the issues? Got to File menu > Project Settings > General and under Video Rendering and Playback, set Renderer to Mercury Playback Engine Software Only.

There is an open GPU-related issue that is under investigation.

Hi.

Can you try the following? Thank you.

Go to Edit> Preferences> Media and remove the checkbox before the item: enable Intel h.264 decoding (requires restart), o (12.1.2) Enable hardware accelerated decoding.

then restart Premiere and try, and tell us.

Unfortunately we have the same problem here. Why is Noone responding to this issue?

I've even created a new encoding and a responding ingest preset with the dimensions countered so formerly 1280*720 turned to 720*1280 but after connecting the proxy with in my project it will be shown flipped and become useless for the work process.
