Before I exported the presentation i tried to preview it and it also not showing some of the inserted images & the background as well. I can not send you the file because it is too big around 230MB.
i have tried to insert a video clips it freezes the loading, if i import the sound track i can hear it but no video. and even not imported the audio it freezes the loading.
i have lots of downloaded from youtube using keepvid and it doesnt play the video only the sounds i can hear. can you give me sample project with sample of video on it.
