Is there an app (or apps) that can upload custom videos on vine? And is there an app to add music on vine?? I searched this all day. If you know an app that will help please post here.
Sorry for my bad english
No, there isn't. WP locked down video in the OS. 8.1 may have removed that, I don't know, but so far all we have is a video trimmer App. I'm hoping for some big time Instagram/Vine editing Apps soon!
I tried playing a song in the background on my phone quick. The official Vine App just stopped the music. 6sec was closer, but it still paused the music in the background while I recorded. So I guess, you'll have to have the music playing on another device while you record.
