When I try to drag a video I made using Logicapture on my C920 webcam, it only drags the audio files. The video file drug in with it is extremely short and i have no preview. It has worked with one video previously, but since then I cannot do anything at all. I'm using SONY VEGAS PRO 17. I'm on a windows PC. I don't think its a codec thing because this has worked in the past for me. Thanks in advance for any advice.
