I recorded a 13 minute video (in medium resolution), using the webcam and snagit. Then I tried to save it as an MP4. It told me I lacked memory, and would not save it. (It would have been almost 4 Gigabytes). I was using a laptop with plenty of drive space, but the memory I think was the bottleneck. It would be nice if Snagit tells you when you start recording a video a message such as: "with your memory limit - don't exceed 6.32 minutes at this resolution" or something helpful like that.
