I renamed all the files from separate folders and moved them all into one folder. I reopened the project and reassigned all the new file numbers to the each video stream. Then I spent four hours going through each stream making sure it played and if I had to I'd preview it from the folder and then play it in the stream sometimes slightly editing it and I thought I had it because this would eliminate the blackouts in the video preview window. Or so I thought. After twelve hours rendering all my hard work was a bust. I had ten fricking blackouts of video throughout my three hour video project.. I'm so depressed I'm listening to the first two Roxy Music albums to try and perk up my mood. No surprise it isn't working.

I checked the box for system info. I still have to find my records to enter the video card and audio card info. I'll try what wwaag suggested this morning.

My 3 hour project I have edited and rendered last night after good advice from several of you is giving me fits that I thought weren't going to show up in the rendering. As I was editing my project I would notice a video stream would some time need "coaxing" to be seen in the video preview for example it would be blacked out at first but if I previewed it from it's folder it would play in the video preview and then when I would play it from the timeline it would then play fine and not be blacked out. Before I went through my ten hour render last night I previewed each stream and then made sure they played in the video preview from the project video track. When my render finished I had maybe 6 streams that were blacked out and the rest (50 or more) were fine. I don't understand the inconsistency. Maybe it's because there are five folders that contain all the video files and maybe I need to move them all into one folder? Then I would have to rename the ones that have the same name "File0001" for example in several folders to "File0001-2" from the other folder & "File0001-3" from the next folder, etc?
This is my first time doing a big project with HD. What can I do to make sure all the video streams render? Please look at my other post on the topic of "Rendering #3 Hour Project in HD " for more info. I'm stuck at this point because obviously I am inexperienced. Anyone who has experience in this matter that can help, I'd appreciate hearing from. I just updated my system info which I thought was there. It must have been deleted at some point but that might help answer some questions you might have about my system.
