Hi there i am pretty new to this sofware and i am having trouble exporting one of my videos after successfully export two previously. The one i am having trouble with has quite a few video tracks and audio and i wondered if that was the problem? Also is there a way to have a video and get rid of the audio? I have a lot of audio tracks as when i was taking the video there is audio? and i noticed it can cut out video if it is already on the sequence? my video is 8mins and has quite a lot of layering, i have been using them for youtube. the first time i imported as a youtube quality video and it only did 2 minutes? I would appreciate any help thank you Nicola
