We don't support text over video in this current release. This is definitely on our radar. Thanks for the feature request! Please keep looking out for future updates from Clip.
How about Audio per Clip and not like it is now that you have one music file for the entire project. I want to make a cut scene and add audio to only a part of the video not the entire project. I know this can be done with Kine Master Pro. Clip can be so much more if it rivals Kine master Pros features.
