I shot a video in portrait mode on iphone, and its a mov file with a vertical aspect ratio (ie, when i open it in quicktime, it has no black areas on its sides).
I open that video in imovie version 10.3.5, and i cut some frames to shorten the video, i then export it as a mp4. Now when i open the mp4, quicktime has black areas on its side.
I read that i have to first preserve the original ratio by going to crop setting in imovie and select 'Fit', then edit, then export. I did that, and still it comers out with black areas on its side.
Same when I upload it to Google Video and play it, it plays in a very small window on my phone, whereas the orignal un-edited video plays on full screen veritically on my phone.
I've spent 8 hours on this and can't fix it.
How do I edit this video and still have it preserve original aspect ratio?
