Posting to one that doesn’t? Reelspan can reframe the video to each network’s shape when you post.
Close counts
Shapes within 2% match, so 1080 × 1350 reads as 4:5 and 1920 × 1088 as 16:9.
Preferred first
“Preferred” means it is the network’s first choice; “fits” means the network takes it as it is.
Your file stays here
Only the file’s size is read, in your browser. Nothing is uploaded.
Then post it everywhere at once.
