Please help me since this problem had been driving me up the wall the last 2 days! I'm trying to render a 1920x1080p video which is not from a single video but its a project with clips from 27 videos.Every time I would render the video from Sony AVC or MainConcept AVC I would get a black screen with audio only then audio would cut out halfway in the video.

In my project some of my clips would say "Media Offline" then if I was to tab out of the program and then tab back in the clips would load up fine.When I would go to my preferences and check off "close media files when not in the active application" as suggested in some threads I ran across,half the clips would load and the other half of the timeline wouldn't load unless I go to that side of the video.

Here are some things I've tried,
1.Replaced and selected original videos clips came from.
2.Uninstalled and re installed my Quicktime.
3.Downloaded driver update for my video card.
4.Downloaded ffdshow MP4 codec
5.Downloaded a codec pack
6.Downloaded and running current version of Direct X
7.Moved all the original videos from my external hdd to my internal hdd
8.Changed my virtual ram from around 2 gigs to 12 gigs

I did all this to ensure that all my drivers and plugins are up to date and that the video files are being read and not missing.I don't know if my PC is too slow for movie studio 13 although according to the requirements I should be good in the recommended setup but yet again I heard when your doing 1080p editing the requirements intensifies so here is my PC information,

I am using a AMD Radeon HD 6850 video card.

To answer a future question yes,I've made projects before and rendering wasn't an issue although those videos were from a single video file.

I am at a real loss on how to solve this issue,I made such a beautiful project and I would like to solve this rendering issue so I could upload this amazing video to my YouTube channel!
