Best Video Dimensions and Export Settings for Articulate Storyline (Premiere Pro)

Interested in others' opinions, but I don't think I've ever seen 960x540 as any kind of recommended resolution so much as it's just a historical default. The widescreen default was actually upped to 1080p recently, but some designers have audiences that may lose out with large course files. I like 4k resolutions as much as the next person, but I think the course dimensions should be determined by things like audience ethernet bandwidth.

I don't think I have any tips personally from using Premiere to publish for Storyline. I simply try to use the Export modal's preview tab to get a good idea of how the video will look before publishing. If it's clear there, it'll be clear when I've officially exported it, so I just tweak bitrate and things until it looks acceptable.

For Storyline, be aware that mp4s and webms you import will be given a "Yes" toggle for a compression setting. This will recompress the video to a level you will undoubtedly find unsatisfactory, so just make a mental note to turn off compression for each video you import unless of course it's something you want.
