Probably not the correct place to post this, but I reckon this group may be able to know the answer to this. I've tried to figure this out for the past few weeks and I still haven't found the answer. Basically, I'd like to how the likes of Mplatco and other "influencers" on snapchat is able to upload content to his snapchat account with music playing in the background. I know how you have music playing in the background, but he's obviously using something else in order to upload his snaps to snapchat. Someone on twitter asked him what he uses to edit his content to which he replied: "I edit everything on my iphone s6 using only imovie and perfect video app. Now, I've tried this approach by taking a few videos using the snapchat app, but downloading them straight to the phone...not uploading them to snapchat. I then export them to imovie on my mac, add a music track, and then pop the finished file back onto my camera roll. However, when I use a third-party app snapchat app to upload the clips in 10 second segments...the clips are very grainy and pixelated. This happens after the third party app uploads them to snapchat....so the app is obviously compressing the clips. I've tried this using the ios app like he mentioned (perfect video app) and the same thing happens, with the video showing up in snapchat as very grainy. Now, anyone that watches Mplacto on snapchat will see that his content is crystal clear...but this where I'm stuck. How does he maintain perfect video quality when he uploads his snap content? Myself and a few others have tried to replicate his process (to upload externally edited content) to snapchat but the resulting video/image quality has always suffered. Any help would be very much appreciated as no one can give a logical explanation to this. Edit: I suspect he's using a jailbroken iphone with some app? No idea though.
