product: Movie Studio 14.0 platinum
I recorded in portrait mode, height:1920 width:1080 using my Google Pixel smart phone.
Now I want to edit this video, but keeping the same format and not adding black bars on the sides.
So I choose MP4, Sony AVC/MVC, custom template width:1080 and height:1920.
Alas then it complains "invalid argument". It will however let me make it width:607 by height:1080, which is the correct aspect ratio, but I would prefer a higher resolution. Are there a combination of settings that will allow that please?
