This usually problem usually occured at random, and after 2 failed attemps the third rendering would be completed perfectly, now it has happened all week around, therefore I couldn`t really call a pattern for this problem.
For the Video Capture settings in fraps I use: 60fps, split movies every 4gigabytes, record win7 sound and also record external output which is my headset. All the files I record with fraps have the resolution of 1360x706.
When importing the files into Adobe Premiere Pro CS6 and making a new project I usually go for a format of 720p 25, then when I place the media in the sequence I used not to modify it to have the same settings. When I was done editing I would choose Export>Media then choose the format of H.246 and the preset of YouTube HD 720p 25 and if then tick the "Scale to Fill" so that the video would have no black margins and it would have been perfectly fine.
My videos or of a length of aprox 10 minutes so the rendering would be done in an hour or so. Now, it has failed every single time, in what meaning? Well, the rendering always took as much as it should have been but the end product, the output rendered file, is only 24 bytes of space!
Hope this helped you make an idea and possibly spot out the problem.
