I feel like a good idea would be to allow users to choose whether or not they would want their video to fade in and out or not. It seems if a video is at the max time limit, it fades out, and all videos fade in. This should be an option you can toggle when uploading the video.
Also, I feel like we should bring back all the features the original Vine camera had, such as looping, reverse, music additions, other Vines (now bytes), etc.
That seems like a lot, but I’d love to see at least the fading options put in.
