First, is there a red line above your clips on your timeline? If so, you need to render your timeline. Running the program with unrendered video on the timeline can result in out of memory reports.
Also, when you place your video on the timeline, is there a red line above it before you add effects to it? If so, you are not using the correct project preset.
When you start your project, go to Settings and select the correct project settings for you Canon 7D, based on the video format and resolution specs your camera is shooting. Using the correct settings, as I say in my books, will save you having to continually render your work.
Thanks for the response! Right now what I have been working in is the instant movie feature to just play around. That is when the errors are happening. The movie does render, but ends up with the errors. I'm pretty sure I have the correct settings for the presets. DSLR 1080...
So, this is not really a memory problem?...I will keep trying the things you have suggested though!
The camera settings for video are 1920 x 1080 at 30 fps. The images are L jpeg format. I have looked, but cannot find where it would indicate defragmented space on the C drive (can you help me out on that one?) Also, have you ever seen the strange image with the foreign language before? That could show up anywhere in the rendered file, sometimes in the beginning, sometimes a few slides in...
I chose the video settings in the preset and to save it to the C drive...The quad core is 2.40 GHz and 2.39 GHz. Perhaps that isn't for Full HD?...
