It worked fine for a few weeks. Now it crashes if try to play back the video I'm editing after about 6 seconds EVERY SINGLE TIME. I have to close the app, open, and attempt to line up the audio with the video by playing it back. Can only work 6 seconds at a time. It also loses bit and pieces of the project you are working on after 24 hours. Some are lost completely. Too bad it doesn't work right. It would be great if they can figure out how to keep it running for even just one solid minute.
