Unfortunately, I had the exact same experience as leahz.

Despite a seamless editing process for the most part, it took me TWO HOURS to output one video-the app kept crashing on me while it was processing.

Totally unacceptable.

Also, the captioning function is basically useless. I cannot understand how they didn't allow the option to move captions. It is so low you can't even see it on social media.

Every video editor I've ever used has allowed for movement, rotation, and resizing...you can do none of this with BigVU.

Super disappointing product. Stick with something else.
