Beware, video erased by app

I purchased this app a week ago, and used it Saturday night to get some video. Sunday I opened the app and clicked "render", and waited. It apparently finished something, and gave me an error that the video was in the wrong format. (??!)

Now there are no videos listed in the app, no video to be found in my Camera Roll. Its just gone.

I emailed the developers Sunday, and have still not received any response as of Tuesday mid-afternoon.

Dont bother with this app.

===================================

Update: I was contacted by the developer on Wednesday, and he did not believe the app deleting video was a concern. I thought it was "a one off case", and that he was hearing of this behavior for the first time. Ive notified Apple Support and requested a refund.

This developers "support" leaves a lot to be desired. I again warn you to beware this app.
