Hello.

Ive been making a video in Sony Vegas 7 for a while now and just got around to finnishing it, i was so happy i finnaly finnished my work and waited joyfully for the 10 minute video to render which took over an hour.

Anyway upon playback to check everything was good to upload. I was shocked at around the 7th minute one of my video clips showed up as black. The music still played and the distortion effect which played over the clip at the end still played but there was no clip.

I tried to render it again and the outcome was still the same.

I rendered it into "Windows Media Player V9 (.Wmv)" always,

Ive made videos in the past with these settings and they came out ok.

The clips i used were all in .Avi and ive never had this problem with any of these clips. The clip which came out black i used in Windows movie maker last year in a video and it came out fine. So im really stumped on what the problem could be
