please help! so i am new to this editing software, and i use it mostly to make music videos to upload to youtube. when i'm finished with a video, i save it, & play it back to make sure nothing is wrong. then i convert it to a file type that youtube supports. i upload the video to youtube, but the sound & audio doesn't match up! weirdly, it is ONLY off when uploaded to youtube; when i play it back before uploading it's fine. the sound is behind the video footage. i don't understand...i've created a lot of videos and the same problem has happened to all of them. maybe i'm not converting it to the correct file type? if anybody that uploads their magix videos to youtube can tell me what file type they convert it to , that would be greatly appreciated. idk if i'm being clear enough but please please help! thank you :)
