In the last months i have had some troubles with video exportation. If i try to export in .mp4, .avi, .mov etc it exports only audio and no video, that appears as a black screen. The only format which works is .wmv.
How can i resolve this problem?
Thank you in advance and sorry for my english
Please give us a screenshot and some more info (SC version, your system, OS, etc.).
Maybe you have deactivated the video track and only audio is open?
See the #FAQ
Also stop using the Advanced mode of export and use the defaults or Default preset.
