    Why am I getting black footage during & after rendering, after the end of video in CS5?

    computerskillme Level 1

      This just started and is completely odd.  When I go to render my clips, I export them to the Adobe Media Encoder, and then when all of them are there, I click on 'start queue.'  The videos take all day to render, (I tried rendering four clips to Windows Media Player format, and each clip is about 30 minutes in length), and there is an additional hour of black footage after the end of the video.


      I looked at my project, hitting the 'home' and 'end' keys to make sure that the end of the video ends where it is supposed to end.  I made sure that all the eyes are showing in the project too.  In the 'export' area, I make sure that the work area has the same timeline as my project.


      Still a ton of black footage is created.  So I did a test with 50 seconds of footage.  And it claims to take an hour to render, and as I'm looking over, it's now rendering black footage.  What is going on?


      Here is the settings that I'm doing for the video clips, as I run a VOD (video on demand) website.  (So if you see something I could be doing better with the settings, please let me know, thanks!).

      I hope that this is everything that's needed.  If I'm missing something, please let me know.  I've been making vods for years.  I've never had this happen before.
