Cropping 4k video to 9:16 1080p is pixelated in Premiere iPad

I have tried the same original video file in other iOS apps to convert it for mobile use, but no problems with other apps. In premiere the exported file looks “blocky and pixelated” i have tried all export settings. The original is H264, but i have tried other 4k files with H265 codec and the same result. 

    Correct answer TaneliFoto

    Seems that the main problem of my troubles was that instead of the “fill” option i used the Transform controls and zoomed in from there and somehow that had a worse quality to video end result than the “fill” button.

    At this time, it seems using the Fill control seems to produce acceptable results. 

    Thank you all for help,

    Hey TaneliFoto –

    A couple of screenshots might help us to understand the issue. Let me know if I’m understanding.

    • You start a new project with your 1920x1080 (horizontal) video
    • You use the Aspect Ratio icon to change your project to 1080x1920 (vertical)
    • The video looks normal while it’s in the app, but after you export it, the video is pixelated when you play it in your Photos app on your iPad.

    Are there any other videos in the project other than the horizontal one? 

    Let us know,
    Caroline

    @TaneliFoto,

     

    You're working in PR desktop and exporting, right? I don’t see this.

     

    What steps do you take in PR?

     

    Pick one set of export settings and tell us what they are?

     

    Screenshots would be helpful.
