I used camstudio. I capyured maybe one minute, it created a 1gb file. vimeo only allows 500mbytes. What settings did you use to keep the file small?
thanks
Camstudio will create a raw file that it uses for editing... it can be large.
Later you "produce" a video and fix the size and quality.
This week I captured a video conference call with a slide presentation -- it was a 1 hour presentation. To 'produce' a mp4 file I selected high definition (1280x??) and it generated a quality file with sound that was 54MB.
