Currently, this app converts any 4K video into 1080p before saving that 1.0 or 1.5 seconds of footage locally. I would like the app to support 4K video and not downscale the video. 😁 There is a FAQ post about this, and they say that they are waiting until there is more 4K adoption. However, released back in 2015, the iPhone 6S could record 4K video @30 FPS. I understand that storing and handling larger files is more difficult, but I don’t need cloud backup capability. Currently, I’m saving my 4K videos, which are more than 1 second, in my camera roll and waiting until the app supports 4K. Because of this, my videos take up more space because I can’t reliably crop them to 1 second without tedious work in iMovie or something. In a nutshell, I hope 4K support comes soon. A user who originally paid $4.99 I love the app though ❤️ I show it to all my friends.
