I have an Andriod Oneplus 7 pro 8gb RAM- so should be quite capable.
On Premiere Rush (mobile version) I was able to edit the video fine, putting different clips in etc. I recorded the clips in 1080p. The completed video is about 9 minutes long.
When I tried to export it (I tried 1080p and 720p) both times the rendering worked but when I played it back the video kept glitchy and it was really choppy. At one point the video went green very briefly.
It looked fine in the preview when I was editing it, don't understand what has happened.
