Instagram video settings with VideoExport and FFMPEG

Hi everybody!

I am trying to export a high resolution animation to Instagram using Video Export but after the upload it is getting heavily compressed.

I am using size(1080, 1350) and videoExport.setFrameRate(30). I’ve also tried to convert the resultant video using these settings, but without success.

ffmpeg -i PROCESSINGVIDEO.mp4 -c:v libx264 -profile:v main -level:v 3.0 -x264-params scenecut=0:open_gop=0:min-keyint=72:keyint=72 -c:a aac -preset veryslow -crf 23 -r 30 -sn -f mp4 OUTPUT4.mp4

Could someone share a VideoExport preset that works for Instragram ? Like these advanced settings on the library example.
