[Wlug] Video Editing

Anyone do any video editing? I've tried using pitivi to edit videos. It usually crashed. Recently I tried putting a series of images in and creating a video. I successfully created a video once. Now everytime I seem to create a file without any video content. The video isn't going to be long or good. I was showing my son how lego stop animation is done. I only did a 8 images and they aren't perfectly aligned. I used a small tripod but press the picture button must have moved the camera a bit. Probably need to use video and screen capture images so I don't touch the camera. The images also have slightly different light levels. If anyone has suggestions on fixing the images to be consistent let me know.
