is exporting video with avi or mov 720P or 1080 fit with apps like instagram and snapchat as video dimensions ?it it ok or the video will not uploaded because of wrong dimensions ?
It'll export into a 16:9 format.
You can still upload this to Instagram.
what about snapchat it's the same ?
Never used snapchat, so no idea.
Presumably, if you can upload an MP4, AVI, MOV or WMV video to snapchat, then you should be fine.
Why don't you try yourself?
ok , thak you.
Let us know your results, in case someone else is wondering :)
