Question

Output aspect ratio 9:16 won't stick

Hi there

I'm trying to export a 9:16 clip from a 16:9 video to upload to spotify to be used as a spotify canvas video loop.

 

My original video is 3840:2160.

I set the sequence to then export to 1215:2160 which is 9:16

When I go to export the video it gets set to 1214:2160.

 

I am exporting using current version of Premiere and encoder as an mp4 file using the H264 codec

 

If I try to change the width back to 1215 it simply reverts back to 1214.
What is going on here?

You need to use even numbers.

Choose numbers you can devide by 4.

1216 would be a better choice.

Thanks very much this makes total sense.

The math that ended up making this work was as follows.

Start with 1215x2160

then divide by 5

then multiply by 4

you get 972x1728

Then change the size of the video in the sequence to 80% as you have made the size of the video 20% smaller.

I second that. I just tried it on my system, almost all codecs won't accept a width of 1215. Only Apple ProRes does.
