Splice problem? Can i fix it? Or similar free app?

I LUV splice. The free verision has exactly what i need except now my videos are black. I use it for viddy. When i make a video on splice & hit view you don't see the video, you can only hear the audio, is there a way I can fix that? I want to stay with the free verison cuz i don't wanna pay $3.99 for the other. If there isn't a way to fix that is there another free video app just like it that i could use for the iphone?

That's a great app. I would recommend using "free video editor" It's very easy, but the adding transitions feature cost.99 cents. The best video editor is "iMovie" it's made by apple, but it does cost $4.99. However, you can add in titles to videos, adding a video takes literally a second, record audio, add music, transitions, and add amazing themes. The app is feature rich. Even though it's 5 dollars it's amazing and it gets updates with new things.
